2.2.1 Display

The DAT400 display is a LCD with electro-luminescent backlight. It has alphanumericand graphical capabilities:

• in alphanumeric mode with built-in character patterns, it can be used to display 8rows of 16 characters (8 x 16). Refer to 0 Built-in display character fonts for details.

• in alphanumeric mode, with user-defined characters, it can display 8 rows, with 15,16, 20 or 21 characters per row (software selectable). Characters can also bedisplayed in reverse mode. This feature is also described in 2.2.1.1;

• in the graphic mode, it can display 64 (Vertical) x 128 (Horizontal) dots.

It features:

• Software contrast control to adjust view angle according to operating temperature.• Backlight for poor light conditions (switchable ON/OFF by software commands and

keyboard).• Backlight programmable autopoweroff timeout to save power consumption.• Programmable custom characters supported by either optional hardware or graphic

drivers (refer to Programmable Characters for details).

Contrast and autopoweroff time-out can be adjusted through Set Up procedure andOS1541 functions.Cursor shapes can be changed by OS154 functions.

The functions implemented within the OS154 allow to easily control all the displayfeatures from the application program level.

Refer to 6.1.1 LCD Liquid Crystal Display for complete technical characteristics.

2.2.1.1 Programmable Characters

OS154 system calls allow to program the display with X (X= 15, 16, 20 or 21) columnsand 8 rows, displaying user-defined character fonts. Characters can also be displayed inreverse mode. Refer to Dat400ProgrammerGuide.doc for more details.

1 OS154 is the DAT400 operating system.




2.2.2 Keyboard

Two types of keyboards are available (refer to FIG. 5 and FIG. 6):

• 27 key full alphanumerical.• 18 key numerical/functional with alphabetic capability.

Both keyboards have rubber button type keys with epoxy resin protection. The rubberkeypad is completely sealed against water, moisture and dust.

Both keyboards are available with backlight to allow the DAT400 operation in the darkor poor lit environments (i.e. parking fine issuing at night).

Both the rubber keypad and dark gray serigraphy may be easily customized on request.

FIG. 5 DAT400 with alphanumeric keyboard (enlarged on the right)



FIG. 6 DAT400 with numeric keyboard with alphabetic capability (enlarged on the right)

2.2.2.1 27 key full alphanumerical keyboard

The 27 keys are 2-position keys, that allow to select two different characters with onestroke.As a default, each key returns the character printed at the center of the key (i.e. thenumbers): the cursor appears as the underline character.

After ALPHA key is pressed (toggle key), the keyboard enters the alphabetic mode,indicated by a block cursor blinking on the display. Depending on where you press thekey, on the left or right side the keyboard returns the character printed on the same sideof the key (if available).

If SHIFT key is pressed, the keyboard enters the shift mode, shown by a small fixedcursor on the display. The returned character is the one printed on the dark grayserigraphy on atop of each key. SHIFT key is active only for the next hit key.




Example:

Refer to the following key:

By default at power on the key will always return the character “1” (numeric mode).

After pressing ALPHA if you hit the key on the left it will return “G” if you hit it on theright it will return “H” (alphabetical mode).

If you press ALPHA again the key will return “1”.

If you press SHFT and then the above key it will return the “F1” code. The keyboardthen returns immediately to the previous mode.

ALPHA mode may be activated and deactivated also by the application program withouthitting the alpha key.

The use of ALT and CTRL keys is defined by the custom application, if any.

2.2.2.2 18 key numerical/functional keyboard

The meaning of the keys is self explanatory.

The keyboard usage is software programmable:

single-stroke usage Numeric mode.

Only one character code is related to each key.E.g.: pressing the ‘1’ key, the character 1 is returned.

multi-stroke usage Alphabetical mode.

The keyboard can be used for alphabetic input, as in cellularphone. Hitting several times a key, you can have the lettersprinted above.

E.g.: pressing 4 times the ‘2’ key, you obtain:

1st stroke: ‘2’;2nd stroke: ‘A’;3rd stroke: ‘B’4th stroke: ‘C’.

F1



2.2.2.3 Software information

The C library of OS154 contains the routines to handle the keyboard.The Operating System returns ASCII codes for each pressed key. The returned ASCIIcodes can be managed by the application program.

2.2.3 Built-in Miniprinter

DAT400 features an impact miniprinter for fanfold multiple copy paper with an internalhousing for the paper stack. The fanfold paper size is 57x152 mm (2 ¼ “ x 6”).

Two models of miniprinter are available:

• Model 1: 24 characters per line with 2.5 lines/s speed.• Model 2: 40 characters per line with 1.5 lines/s speed.

The printing area and the paper size is the same for both models. The model 2 actuallyuses a condensed character font thanks to a higher horizontal resolution.

The main miniprinter characteristics are:

• graphical capabilities;• internal fanfold paper housing for 40 double copy sheets and about 90 single copy

sheets;• 57 x 152 mm (2” x 6”) sheets;• friction feed;• optical automatic alignment of each form

A special soft plastic carrying case (optional accessory) is provided for paper and printerprotection against rain.

The miniprinter full technical characteristics are detailed in 6.3.1.

The miniprinter has two character sets, each containing 244 characters (font 1 and font2), which can be software selected. 8 user defined characters can also be added.




FIG. 7 DAT400 Miniprinter fonts.

The main miniprinter software options are:

• Font size selection:• Regular• Double width• Double height• Double width and double height (expanded mode);

• Graphic mode;• 8 software programmable custom characters;• 180 degrees rotated characters;• Internal EEPROM to store miniprinter configuration.

The list of the codes for the miniprinter management is contained in 6.3.1.1.

The miniprinter is connected to the internal COM2 of DAT400 CPU.

In order to use the miniprinter, the COM2 of DAT400 CPU must be programmed asfollows: 9600, N, 8, 1, XON/XOFF software handshake. That COM2 programming is



managed directly by OS154 functions. Refer to DAT400-PrinterProgrammingVs11.pdffor details.As COM2 internal port is switched between the miniprinter and the integrated bar codelaser scanner, when the miniprinter is in use, the integrated bar code laser scanner cannot be used and vice versa.OS154 C library contains all the routines to manage the miniprinter. Refer to DAT400-PrinterProgrammingVs11.pdf for details.

2.2.3.1 Paper and inked ribbon

The impact printer requires an inked ribbon cartridge. The ribbon is continuously re-circulated by the printer motor while printing.

2.2.3.2 How to load the paper

In order to load miniprinter paper, it is required to have an application program alreadyinstalled into the DAT400 with a charged battery pack in place.All application programs provide two basic functions to load the paper:• the System Menu option to load the paper anytime• a pop-up function that appears when paper ends while printing

As the procedure is the same as an example in the following you will find how to usethe System Menu function.

• Switch ON the DAT400, select “System” option and than “paper load” (usually allapplication programs have a System Menu option, but you may also find it with adifferent name)

• Remove the printer cover and insert the fan-fold paper stack in the DAT400 paperhousing (FIG. 9 Insertion of fanfold paper stack) paying attention that the black markon the right edge of the first sheet of the paper stack is upward.To correctly open the cover you have to use two hands to pull the two little lockinghooks on the bottom of the printer cover. By using one hand only is quite likely thatyou push the hooks instead, so the cover can not open.

2.2.4.3 DAT400 RS485 and RS422 interface

An external RS485 (or RS422) interface adapter is available on request for multidrop,long distance communications.

2.2.5 Buzzer

Looking at the back of the DAT400 on the top right side, there is a small grid windowfor the buzzer (see FIG. 1).By means of OS154 relevant functions you may activate it and change the beepduration.

See 6.1 for technical specifications.

2.2.6 Backup Battery

Internal backup battery guarantees the SRAM (Static RAM) data retention and the RTC(Real Time Clock) uninterrupted operation when:- battery pack is discharged- battery pack it is not plugged into DAT400- DAT400 power is OFF.

The characteristics of the internal backup battery are the following:

Type : Lithium batteryVoltage : 3.6 VCapacity : 850 mAh

The backup battery in not rechargeable (primary battery).

The backup battery discharge time is about 6.5 years at 25°C ambient temperature andabout 4.9 years at 50°C.

DAT400 keeps SRAM data (both operating memory and mass storage) and RTCoperation until backup battery voltage is greater than 2V.When backup battery voltage is lower that 2V (discharged backup battery), SRAM dataand RTC information may be lost.

The OS154 operating system functions allow to measure the back-up battery voltage, sothat some warning message may be issued to advise that the DAT400 needs back-upbattery replacement.




Warning: For data safety reason, it is recommended to send the DAT400 to anauthorized service center for Lithium back-up battery replacement, within 5 years ofyour DAT400 purchase date or when the battery voltage is lower than 3.3 V.



2.3 DAT400 optional built-in peripherals

2.3.1 Laser bar code scanner

DAT400 may have a built-in laser scanner to read all the commercial and industrialmono-dimensional bar codes (for bi-dimensional bar codes please contact your 4P’sdealer or 4P directly)A suitable scanning beam inclination and the center handgrip of the 18 key DAT400version with its lateral strap, offer a very comfortable way of working for intensivebarcode scanning application.

The decoded bar code standards and some bar code laser scanner functions, detailed inthe following, may be selected/activated by the application program.



PARAMETERS DESCRIPTION

Security This parameter selects UPC/EAN decode security zone and levelType This byte enables or disables decoding various bar code types. The

barcode controller autodiscriminates among several enabled bar codetypes.

Option A When code ID option is selected, the decoder appends a bar code typeidentification byte to the decoded data.

Option B The UPC/EAN supplemental auto-d option selects whether toautodiscriminate between UPC/EAN symbols with or withoutsupplemental.When this option is enabled, the setting of bits one and two of theprevious parameter (Decode 2 and 5 Digit Supplemental) is ignored.

Interleaved length 1 Code Interleaved 2 of 5 can be read if the length has been specified inthis parameters or in the following.

Interleaved length 2 Refer to Interleaved length 1 parameter.Preamble The decoder will append any ASCII code set here to the beginning of a

decoded message(*), provided that it is not the number 0x80.Postamble1 This is one of the postamble bytes that the decoder will append to the

end of a decoded message(*).Postamble2 This is the second postamble byte that the decoder will append to the

end of a decoded message (*).

*) A message is the character string returned by the bar code laser scanner.

Refer to DAT400-LaserProgramming-Vs10.doc for more details.

Warning : It is strongly recommended to always use barcodes with check digit andto enable the “check digit” verify option of the DAT400 bar code scanner. This preventsany decoding errors that could occur for wrong scans due to damaged or poorly printedbar codes, difficult light conditions, etc.

2.3.1.3 Laser scanner safety regulations

DAT400 bar code laser scanner is CDRH Class II certified, equivalent to EN 60825-1(Safety of laser products – Part 1: Equipment classification, requirements and user’sguide) Class II.Bar code laser scanner with Class I certification is also available. If your applicationrequires Class I certification, please contact 4P.

2.3.1.4 Software Information

This integrated bar code laser scanner is internally connected to the COM2 (FIG. 4) ofDAT400 CPU.




In order to use the bar code laser scanner, the COM2 of DAT400 CPU must beprogrammed as follows: 9600, E, 7, 1. That COM2 programming is directly managed byOS154 functions. Refer to DAT400-LaserProgramming-Vs10.doc for details.As COM2 internal port is switched between either the integrated bar code laser scanneror the built-in miniprinter, when the integrated bar code laser scanner is in use, theminiprinter can not be used and vice versa.OS154 C library contains the routines to manage the bar code laser scanner (refer toDAT400-LaserProgramming-Vs10.doc).

2.3.2 Magnetic Stripe Reader

DAT400 magnetic stripe reader allows the DAT400 to read any magnetic ISO compliantcards, like the credit cards. DAT400 can not write magnetic cards.The magnetic card can be swiped in both directions, as shown in FIG. 16 DAT400Magnetic Stripe Reader.

FIG. 16 DAT400 Magnetic Stripe Reader

The data are recorded on the magnetic stripe into three tracks as follows:

Track 1 IATA developed by International Air Transportation Association (IATA),contains alphanumerical information for automation of airlineticketing or other transactions where a reservation data base isaccessed.

Track 2 ABA developed by the American Bankers association (ABA), containsnumeric information for automation of financial transactions. Thistrack of information is also used by most systems that require anidentification number and a minimum of other control information.

Track 3 THRIFT developed by Thrift Industry, contains information, some of whichis intended to be updated (re-recorded) with each transaction (e.g.,Cash Dispenser that operate “off-line”).



The related reference standards are:

ISO 7810 Physical CharacteristicsISO 7811-1 EmbossingISO 7811-2 Magnetic StripeISO 7811-3 Location of Embossed CharactersISO 7811-4 Location of Tracks 1 and 2ISO 7811-5 Location of Track 3ISO 7813 Financial Transaction Cards

For full official specifications contact:

AMERICAN NATIONAL STANDARDS INSTITUTE(www.ansi.org)

Tracks have different physical positions, recording density (bits per inch), characterconfiguration (number of bits per character, including Parity Bit) and informationcontent (type of characters, that is numeric/alphanumeric, and number of characters pertrack), as summarized in the following:

FIG. 17 ISO 7810 Magnetic card characteristics

According to the above standards, DAT400 can only read stripes encode with F/2Fmodulation. If other encoding modulations are used, please contact 4P technical support.DAT400 is able to decode also the F/2F cards that have a gap; a gap is a non-magnetized zone in the middle of the track. The decoding software recognizes this kindof cards providing there is a minimum number of ‘0’ bits just after the gap (at least 15‘0’ bits).

DAT400 magnetic stripe reader can be supplied in two options:

Option 1 Track 1 and 2 magnetic readerOption 2 Track 2 and 3 magnetic reader

http://www.ansi.org/




DAT400 can read both low energy (300 oersted) and high energy (3600 oersted) tracks.

DAT400 Magnetic Stripe Reader consists of the magnetic head and of the internalrelated circuitry, which is directly connected with the CPU of DAT400 and allows theDAT400 to read the information from a credit card or other magnetic badges.The OS154 C-language library contains the functions to manage Magnetic StripeReader, that is reading the bit recorded in the tracks and decoding those bits, accordingto the above ISO standards. This mode is named DECODED MODE.Additionally, DAT400 Magnetic Stripe Reader can also read cards recorded with aencrypted bit sequence. In that case, DAT400 reads the raw bit sequence and the userapplication program has to decode it. This mode is named UNDECODED MODE.

Using OS154 C-language library functions, magnetic stripe reader can emulate thekeyboard and bar code laser scanner input.Refer also to

• Dat400ProgrammerGuide.doc• DAT400-MagneticCardReaderProgramming-Vs10.doc

for details.

2.3.3 Contactless Mifare® interface (ISO 144443 type A)

DAT400 can be equipped with an optional 13.56 MHz contactless smart card interfaceto read and write MIFARE® smart cards, especially tailored to meet the requirements ofa payment card which can be used for multi-application ticketing systems in publictransport and comparable applications. MIFARE® smart card key benefits are highsecurity level against fraud, reliability, fast access and cost effectiveness.

Mifare® interface is located on the back of the DAT400 close to the buzzer grid.

2.3.3.2 Hardware configuration

In the current available DAT400 version, Mifare® interface is mutually exclusive withbar code laser scanner, as these options use the same internal connector. Therefore,DAT400 with Mifare® interface can not have also the built-in bar code laser scanner.

The Mifare interface is internally connected to the COM2 (FIG. 4) of DAT400 CPU. AsCOM2 internal port is switched between Mifare® interface and the Miniprinter, theycan not be used at the same time.




2.3.3.3 Software information

The software functions to manage the Mifare interface are also available. Refer toDat400ProgrammerGuide.doc for details.

2.3.3.4 Secure transaction management

The event of a power loss in the DAT400 is one of the causes when an unfinishedtransaction may occur. It lies in the nature of contactless smart cards, that there is alwaysa certain probability of faulty or unfinished transactions. Consider the case, when thepassenger puts his/her card out of the operation field of a ticket machine just in themoment when the card internal memory is updated. The WRITE operation can not befinished and the card would contain inconsistent data unless special precautions areundertaken.The decentralized solution (in the DAT400) for that problem is:

• data must be stored twice in data blocks and backup blocks;• inconsistencies between data and backup blocks are intelligently interpreted and the

DAT400 corrects data and backup blocks by itself the next time the card is used.

DAT400 algorithm implements:

• data and backup blocks in the same sector;• the following access conditions for that sector:

" WRITE and INCREMENT with key B" READ, DECREMENT and TRANSFER with key A.

The algorithm checks consistency of current data and, in case of inconsistenciesbetween data and backup blocks, it starts with a correction of current data storage beforebeginning a new transaction.

Contact 4P technical support for more information about Mifare® and RF-IDtechnology.

2.4 Removable and Rechargeable Battery Pack

DAT400 is powered by a Removable and Rechargeable Battery Pack, either NickelCadmium (NiCd) or Nickel Metal Hydride (NiMH) type. The DAT400 Battery packsare plugged into their housing on the rear side of the DAT400 without using any tools asshown in DAT400.The fast snap-in connector allows an immediate and convenient in-field batteryreplacement, so guaranteeing a virtually unlimited DAT400 operation.



The Removable and Rechargeable Battery Pack supplies power to all the DAT400 core(2.5) and the integrated peripherals.

DAT400 Removable and Rechargeable Battery Pack contains 5 Nickel Cadmium orNickel Metal Hydride cells with short circuit/over-temperature protection and batterytemperature sensor.

The Removable and Rechargeable Battery Pack service life on the DAT400 is about 20hours (if the miniprinter is not used).

2.4.1 General battery pack handling precautions

Danger: To avoid severe personal injures you must neverdismount, crash or perforate a battery pack, dispose it in a fireor expose it to high temperature.

Danger: the cell electrolyte is a strong alkaline solution and itwill attack the skin or clothes in case of leakage or incidentalcontact. Should the electrolyte contact the skin or clothes, washit off with water. Should the electrolyte get into the eyes, wash itoff with plenty of water, and contact the closest emergencyrescue center.

Warning: An improper battery disposal may cause seriousenvironmental hazards for which you may be prosecuted.Exhausted battery packs must be carefully disposed according toyour country’s regulations. Please contact your local wastemanagement authority.

The following general battery pack information and handling suggestion must beobserved:

• always charge a brand new battery prior its first operation

• do not short circuit the battery pack leads;

• use the battery pack only to power the DAT400;

• recharge them only with specified battery charger (refer to 2.4.2);

• battery packs are subject to self discharge even if not in use. As the self dischargerate depends on temperature, please store them in a dry environment between 10° Cand 30°C (50°F to 86°F). The typical self-discharge rate is 1% per day at 20°C(68°F);

• battery capacity may decrease at low temperatures, but it will then recover to thenormal value when temperature returns to 20°C (68°F);




• when storing the DAT400, please care that the DAT400 ON button is not keptpressed to avoid main battery potential discharge;

• if you will not use the DAT400 for a long time, please remove the battery pack andstore it separately;

• for long-term storage, keep the battery in a dry regular ambient temperature location(10°C to +30°C), where no corrosive gas is present;

• performance deterioration or even leakage could occur if a battery pack is stored fora long time outside its storage temperature range (-20°C to +35°C) or where thetemperature quickly and often fluctuates between extreme temperatures;

• batteries which have been kept stored for a long time shall be completely re-chargedbefore usage;

• the battery available capacity might be lower after a long storage or when brandnew, but it will recover to the nominal level after some charge/discharge cycles;

• dust, grease and moisture on the battery contacts may reduce its power efficiency.Please clean the contacts with a soft moisten tissue (not too wet);

2.4.2 Battery Pack charging procedure

The following table lists the different available chargers, with their typical rechargingtime, connector and recharging procedure.

DANGERNever use the PSC401-L400 wall cube charger

2.4.3 Battery Pack Self Discharge

Both NiMH and NiCd rechargeable battery packs are subject to self-discharge. Thehigher the temperature, the higher the discharge rate.

To be conservative you should consider the following typical self-discharge rates:• 1% per day at 20°C• 2% per day at 45°C.

As an example after a month storage at 20°C, the expected residual stored energy willbe approximately 70% of the initial one; and after a month storage at 45°C, the residualexpected stored energy will be approximately 40% of the initial one.

Warning: Rechargeable Battery packs stored for morethan six months without recharging might irreversiblyloose their original capacity.

After a long storage battery packs should be completely charged before usage.It may need some full charge/discharge cycles to restore the original capacity, but this isnot guaranteed, as the battery pack inactivation process may have occurred if the storageperiod has been too long.




Suggestion: do not to store battery packs for periodslonger than 3 months.

2.4.4 Battery Pack Life Cycle.

Battery pack life cycle is defined as the number of allowed charge/discharge cycles, atspecified charge/discharge conditions, before reaching a final minimum thresholdbattery capacity. It strongly depends on the battery pack usage (charge/dischargeconditions). This is also called as battery aging effect.

There is no guarantee about the minimum life cycle of a battery pack.

As a reference let us compare the IEC laboratory standard life cycle versus the real in-field application.

In the following tables, all the current values refer to the battery pack capacity.The C value is equal to the battery capacity (mAh)/hours. Therefore, if the battery packcapacity is 1000mAh, 0.1C means 100mA current.

Standard IEC conditions are:

ITEM CONDITION

ambient temperature constant 25°Ccharge 100% at low constant current (0.1C) – long duration (16

hours);discharge 100% at low constant current (0.1C);final minimumthreshold capacity

60% of the nominal one

If IEC conditions are applicable, the DAT400 rechargeable battery pack minimum lifeis 500 cycles.

Actual in-field conditions are very different:

ITEM CONDITION

ambient temperature variable (typically 0 to 40°C)charge often less than 100%, at high current (up to 0.3C) – short

duration (< 4 hours);discharge almost never complete, at high current with very high peaks

due to the printer;minimum customer’sdesired capacity

80% initial

In-field applications show that typical battery pack life is greater than 200 cycles.



This implies that for most applications requiring 8 hours autonomy with a single batteryavailable, the battery pack should be conservatively replaced every year for maximumDAT400 performance.

To extend the battery pack life cycle you should use the P164 vehicle charger or thecigar lighter charger when the operator works with a vehicle.

Warning: Rechargeable Battery packs warranty does notinclude:• the aging effect that reduces battery capacity

according to number of charge/discharge cycles• any faults due to the use of chargers not supplied by

4P

2.4.5 Memory Effect

The Nickel Cadmium (NiCd) battery packs might be affected by "Memory Effect".It consists in an apparent service life reduction after many uncompletedcharge/discharge cycles.As an example, let us consider the situation where you discharge battery to 60% of itsnominal capacity and then recharge it to 100% of the capacity for many times. You maysee that the battery capacity is reduced to 60% of its nominal value (it “memorized“ therepeated discharge level).This effect is partially reversible so that the original capacity can be recovered applyingsome complete charge/discharge cycles with deep discharges.

Charging batteries packs by means of P153/6-4, P160, P164-DT, P164-VE and P151/4chargers avoid memory effect.

SuggestionTo reduce Memory Effect when using PSC401-L400 wallcube charger, recharge batteries only when they are fully

discharged and do not keep the battery chargercontinuously connected while operating the DAT400.

Nickel Metal Hydride (NiMH) battery packs are not affected by the memory effect.




2.4.6 Power Management.

The DAT400 hardware and the OS154 operating system offer the following powermanagement features, in order to save battery energy:

Autopoweroff: if a key is not pressed until a certain timeout expires, the DAT400turns off automatically.The timeout period can be set by either the application program orby the Set Up program. The application program can enable ordisable the autopoweroff using the OS154 functions.

Idle-mode: the idle mode is a low power consumption status of DAT400. Whenthe application program is waiting for a key, the DAT400 enters theidle mode, so reducing power consumption.

Backlightautopoweroff:

the LCD backlight is one of the main causes of power consumption.So, if the backlight is on and no key is pressed until a certaintimeout expires, the DAT400 backlight turns off automatically.When a key is pressed, the backlight turns on again.The same applies for the keyboard optional backlight if present.

2.4.7 Main Battery Status Monitoring

It is very important for an application program to identify whether the battery pack isfully charged or almost flat. When the battery pack is going to be fully discharged, theapplication program should warn the user to immediately recharge or to replace thebattery pack. This will prevent wrong operations such as bad printouts and unexpectedshut down.

Battery pack voltage is continually measured by DAT400 and, if it is lower than 5.5Vthreshold, the “battery low” status is signaled.Battery low condition is detected and managed by OS154 operating system to providean acoustic alarm (by default three short beeps) or any other message defined by theapplication programs.

The related OS154 function also returns the battery pack voltage, which should be usedto decide whether to start a print out or not.

Suggestion:If the battery pack voltage is lower than 6.0V, do not print

as it implies a peak current drain from the battery packthat may shut down the DAT400.

All the other DAT400 operations, including laser scanning, can be still performed evenif the battery pack voltage is in the range 5.8V to 6.0V.



2.5 DAT400 CORE

This chapter deals with DAT400 core features, including:

• CPU;• Operating memory;• Mass storage memory;• Real Time Clock calendar;• Analog to Digital Converter.

The DAT400 internal structure is shown in FIG. 4 DAT400 internal architecture: basicunit, optional integrated peripherals and battery pack.

2.5.1 CPU

The heart of DAT400 is a high-performance CMOS Z80 8-bit 4MHz clock processorincluding (FIG. 18 CPU Block Diagram):

• 4 Counter Timer Circuits (CTC)

• 2 Serial I/O Ports (SIO)

• 2 Parallel I/O Ports (PIO)

• 1 Clock Generator Controller (CGC)

• 1 Watchdog Timer

• Power management circuits




FIG. 18 CPU Block Diagram

2.5.1.1 Counter Timer Circuit

The Counter Timer Circuit has 4 independent 8-bit sections operating in either counteror timer mode

CTC sections configuration is represented in the following table:

CTC SECTIONS NAME CONFIGURATION

Section 0 CTC0 COM 2 cascaded baud rate generatorSection 1 CTC1 COM 1 cascaded baud rate generatorSection 2 CTC2 System clock (OS154 tick routine)Section 3 CTC3 Spare for user application

TABLE 1 CTC section configuration

Sections 2 and 3 are hard wired to the RTC interrupt output pin (refer to 2.5.4 RealTime Clock-Calendar).



OS154 library contains the functions to manage CTC operation.

2.5.1.2 Serial Input Output

The DAT400 CPU handles two independent and programmable full-duplexasynchronous serial ports (SIOA and SIOB). These ports are I/O mapped.

The SIOA port is connected to the communication interface COM1 present on DB9F(2.2.4.1) and slide connector 2.2.4.2.

2.5.1.2.1 COM1 Serial Interface

The following communication parameters are user configurable:

• Baud rate : 600 1,200 2,400 4,800 9,600 19,200 115,200

• Parity bit: None Even Odd

• Stop bit: 12

• Bits per character: 6 7 8

Two basic kinds of data communication modes are software selectable, via the relatedOS154 functions:

• Polled mode: communication program is directly managed by application program.• Interrupt mode: communications are interrupt driven.

When interrupt mode is selected via OS154 functions, the communication program mustselect if the XON/XOFF software handshaking is to be enabled.If either XON/XOFF handshaking is disabled or the polling mode is selected, thecommunication program can implement a RTS/CTS hardware handshaking, using therelated OS154 functions.




2.5.1.2.1.1 Hardware handshaking

Hardware handshaking is controlled by two RS232 signals Clear To Send (CTS) andRequest To Send (RTS).CTS and RTS are two signals controlled by the processor during serial communicationto synchronize it with the external device.

• CTS senses external device readiness (Clear to Send).• RTS signals to external device a Request to Send.

FIG. 19 details wire connections for RTS/CTS handshaking between a DAT400 and aPersonal Computer.

RS232(9D)

RS232

FIG. 19 RTS/CTS handshaking wire connections

2.5.1.2.1.2 XON/XOFF handshaking

This type of flow control synchronization is especially useful when passing databetween the DAT400 and a host computer or a peripheral device does not have CTS andRTS signals.

• Receiver: as the DAT400 receives characters on serial port, they are buffered untilthey can be processed. When the buffer becomes full, the DAT400 generates theXOFF character <DC3> (Decimal ASCII control character 019 = hexadecimal 13) tosignal to the host or peripheral to stop transmitting. As soon as the characters in thebuffer are processed and the buffer becomes empty, the DAT400 will transmit asequence of XON characters <DC1> (Decimal ASCII control character 017 =hexadecimal 11) to signal to the device to go on with transmission.



OS154 receive buffer can hold a maximum of 256 characters.XOFF is generated at 75% of buffer full.XON is generated at 10% of buffer empty.

• Transmitter: the DAT400 will respond to XON/XOFF character generated byanother device. When the XOFF character is received on serial port, the DAT400pauses transmission. Transmission restarts when XON character has been received.

That connection is detailed in FIG. 20 Wire connection for XON/XOFF handshaking.

FIG. 20 Wire connection for XON/XOFF handshaking

2.5.1.2.2 Internal Serial Interface (SIOB)

The SIOB Serial Interface (COM2) is internally connected to both the miniprinter andthe bar code laser scanner (see FIG. 4). In alternative to the bar code laser scanner, theMifare® interface can be present: therefore, all the following considerations areapplicable to either the bar code laser scanner or the Mifare® contactless interface.Due to the internal switching connection, the bar code laser scanner and the miniprintercan not be used together at the same time, but, when one is in use the other must be off.

When the application program needs to print, it must:

• initialize the SIOB with the following parameters: 9600, N, 8, 1;• turn the miniprinter on;• turn the bar code laser scanner off;• initialize the miniprinter.




At the end of the print out, the application should turn the printer off to reducethe power consumption.

If the application program needs to scan a bar code, it must:

• initialize the SIOB with the following parameter: 9600, E, 7, 1;• turn the bar code laser scanner on;• turn the miniprinter off;• initialize the bar code laser scanner.

At the end of the scanning session, the application should turn bar code laser scanner offto reduce the power consumption.

All the above operations for the bar code laser scanner and the miniprinter are managedby the related OS154 library functions.

2.5.1.3 Clock Generator Controller (CGC)

The CGC allows the CPU clock generation in the various DAT400 power managementmodes. Usually, DAT400 is in the RUN mode, that is a normal power consumptionmode. In RUN mode, CGC generates the 4MHz clock frequency for the CPU and otherintegrated peripherals. In addition to that, CGC is used by the OS154 in order to stop theclock operation when not needed (IDLE mode), reducing the DAT400 powerconsumption. Therefore, IDLE mode is a low-power consumption mode. IDLE mode isautomatically entered when DAT400 is waiting for the user pressing a key.Even if it is not suggested, the application program can disable entering low-powerconsumption mode (IDLE mode), using the related OS154 functions.

2.5.1.4 Parallel I/O Ports

The two parallel I/O ports are internally connected and are not available for the userapplication program.

2.5.1.5 Watch Dog Timer

The Watch Dog Timer (WDT) detects an operation error caused by Hardware failures orsevere application programs bugs to avoid uncontrolled CPU activity. The Watch Dogassertion forces a hardware RESET of all circuitry.

OS154 offers functions to:

• Enable Watch Dog timer• Disable Watch Dog timer



The WDT could be disabled during the program development to easy softwaredebugging.

2.5.1.6 Interrupts

The CPU is capable of managing the interrupts generated by the following devices:

• PIO• SIO• CTC• RTC

Dedicated OS154 functions serve the interrupt signal to handle keyboard scanning,serial link communications, OS154 basic timings, WDT and integrated peripheralmanagement.

2.5.2 Internal operating memory

Programs run in the main (operating) memory of DAT400. DAT400 main memory mayrange from a minimum of 64kB to a maximum of 544kB.

2.5.2.1 Memory models

This section describes the software memory models implemented in DAT400, usingICC (IAR C-language Compiler) Vs. 3.10. The next section 2.5.2.2 Hardware optionswill detail the related hardware configurations.

After the application program modules (C-language modules and Assembly-languagemodules) are compiled and linked, the linker also locates the object modules into theDAT400 operating memory. ICC has two operating memory models:

MEMORY

MODEL

COMPILING

OPTION

DESCRIPTION

Large -ml (DEFAULT) In the large memory model, logical and physicalmemories have the same dimension (64kB). That areais referred as a linear addressed area.Large memory model is often also referred as “non-banked” memory model.When large memory model is used, the total amountof memory used by OS154 and the applicationprogram must be less than 64kB.The user application modules (both C-language andAssembly-language modules) must be compiled withthe –ml switch and the object modules must be linked




using the non-banked OS154 libraries (refer toDat400ProgrammerGuide.doc for details).

Banked -mb In the banked memory model, the physical addressingarea is larger than the logical one (64kB). In fact, a16kB logical bank (located at the address 8000H-BFFFH) can be multiplied in a number of 16kBphysical banks. The actual number of addressablebanks depends on the available hardware option(2.5.2.2). If 160kB option is selected, 7 banks areavailable; if 544kB option is selected, 31 banks areavailable.Therefore, when banked memory model is used, thetotal amount of memory used by OS154 andapplication program can be larger than 64kB; up to160kB or 544kB can be used, respectively. However,some restrictions apply (refer to 2.5.2.3 Bankedmemory model restrictions). Note that, when bankedmemory model is used, not all application program islocated in the banks, but some special applicationprogram sections (such as libraries and main(.)function) are located outside the banks, in a memorynamed “non-banked area”.

Refer to C Cross-Compiler Appendix for Z80 Microprocessor Family for details,chapter 1.4 “Memory Models”.

2.5.2.2 Hardware options

DAT400 operating memory consists of two parts:

Flash EPROM 32kB sizeSRAM (Static Random Access Memory) ranging from 32kB to 512kB size

The Flash EPROM is a non-volatile memory and so its contents do not depend on thebackup battery voltage.

The Flash EPROM contains:

• OS154 operating system;• parts of the application program code.

No application program read/write variable must be located in that area. Otherwise,when the application program accesses that variable in a write-cycle, it will crash andDAT400 will reset. Application program may also be corrupted and it may require to be



reloaded. Read-write variables must be located in SRAM area. Instead, read-onlyvariables can be located in the Flash-EPROM.

The SRAM is a volatile memory and so its contents saving depend on the backupbattery voltage. Refer to 2.2.6 Backup Battery for details.

The SRAM contains:

• parts of the application program;• OS154 operating system data;• application program data.

There are 3 hardware options:

OPTION FLASH EPROM SRAM Status1 32kB 32kB Obsolete2 32kB 128kB Available3 32kB 512kB Available (*)

2.5.2.3 Banked memory model restrictions

Banked memory model allow using more than 64kB (when hardware is available) inDAT400 programs. But some restriction apply:

• main(.) function must be contained in the AP NON-BANKED AREA;• each object module must be less than 16kB (split your code in several modules if

required). Recall that small modules allow less memory fragmentation;• the banks can only contain code (not data);• application program read-write and initialized variables must be contained in

C000H-EFFFH area (12kB).

Usually, those restrictions are not an issue for DAT400 application program developing.



2.5.3 Mass Storage

The DAT400 Mass Storage is an internal memory area where application program datafiles are stored. It consists of SRAM memory backed-up by Lithium batterywith size ranging from 512kB to 4MB. It may optionally be also Flash-EPROM.

At physical level, the Mass Storage is considered as an I/O device: a byte array withaddress starting from 0 up to the maximum value depending on its size.At logical level, the Mass Storage memory is divided into data files.

Mass storage is managed using the related OS154 and file system functions (refer toFileSystemV10.doc for details).

The available mass storage memory configurations are:

2.5.4 Real Time Clock-Calendar

DAT400 is equipped with a Real Time Clock-Calendar (RTC).

User can read and set:

• Year, month, day, week day• Hour, minute, second

User application software can also set

• Wake-up capability• Programmable time interrupts




using the relevant OS154 functions.

OS154 guarantees Y2K compliant functionality and leap year automatic management.Daylight saving time has to be implemented in the application program.

The wake-up function allows to automatically power-on the DAT400 at a pre-set dateand time.Programmable time interrupts can decrease an internal 8-bit counter, generating aninterrupt (refer to 2.5.1.1 Counter Timer Circuit for details).

A programmable timer interrupt can be also generated. It is hard wired to the triggerinput of the Counter Timer Control (CTC) sections 2 (CTC2) and 3 (CTC3) (refer to2.5.1.1 Counter Timer Circuit for details), decreasing the related 8-bit counter. Interruptrate can be chosen among :

• 1/64 second• second• minute• hour

Set Up chapter explains how to set the RTC.

The internal backup battery (refer to 2.2.6) backs up RTC when :

• removable battery pack is discharged.• removable battery pack is not plugged into DAT400.• during DAT400 power OFF.

2.5.5 Analog to Digital Converter

The Analog to Digital Converter (ADC) measures:

• the voltage of the internal Lithium backup battery;• the voltage of the Removable and Rechargeable Battery Pack;• the temperature of the Removable Battery Pack. That temperature, if the DAT400 is

not in charge, is approximately equal to the DAT400 and ambient temperature.

DAT400 ADC has 8-bit resolution. OS154 related functions allow ADC reading.



3 SOFTWARE CONFIGURATION

The software configuration of DAT400 consists of:

• OS154 it is the DAT400 operating system, consisting of two parts:• EMBEDDED

DOWNLOADERit allows the user to download a newprograms into DAT400;

• BIOS it allows an easy management of allthe DAT400 resources;

• APPLICATIONPROGRAM

it is the user application program.

3.1 Embedded downloader

It is a DAT400 built-in program, permitting to load any other program into DAT400.There are 2 ways of loading a program into DAT400:

• via RS232 serial connection;• from a data file contained in DAT400 mass storage.

The program to be loaded must be formatted in a convenient way as described below.

3.1.1 DAT400 program downloading via RS232 serial connection

The executable code of the program to be downloaded into DAT400 must be in theMotorola format (that is named “executable and downloadable file”). At the hostcomputer side, WinLoadxx.exe (Windows operating system) and Pcloadxx.exe (Ms-DOS and Unix/Linux operating systems) programs must be used, where xx are therespective versions.

The embedded downloader receives the Motorola format strings and loads them intoDAT400 operating memory.

3.1.2 DAT400 program downloading from a data file contained in DAT400 massstorage

The executable code of the program to be downloaded into DAT400 operating memorymust be contained into a data file in DAT400 mass storage. That data file is downloadedinto operating memory via either the related OS154 function or the Set Up menu (referto 5.3.4 for details).The procedure is detailed in the document “Application program upgrade via P153/6rack”.




3.1.3 Embedded downloader protection

The embedded downloader is contained in a Flash-EPROM software protected area.

Thanks to the protected area in no way it is possible to overwrite or damage this crucialpart of software by incident.It is anyway possible to unlock the protection to overwrite the embedded downloader by• following a special procedure to write the Flash-EPROM (contact 4P technical

support for details);• using either a password (to be typed by the user) or an appropriate string to be

included in the executable and downloadable file.

Refer to 5.3 Downloading an application program for details.

Warning:If the Embedded downloader is corrupted the DAT400

must be returned to the factory to restore it.

3.2 BIOS

Refer to “OS154 DAT400 Operating System, Developer’s Guide” for details.

3.3 Application programs

Application programs for DAT400 may be written in C language and developed on aPersonal Computer. Also Assembly language may be used for special functions.Anyway, the use of assembly language requires a careful and deep knowledge of theDAT400 hardware.

Many DAT400 application programs, easily customizable, are available from 4P and4P’s valuable system integrators partners. The most popular DAT400 programs regardthe following applications :

Sales and Marketing Door to door salesVan sales and route accountingIn flight duty free salesOrder entry

Services Gas, water, electricity meter readingParking fine issuingMobile fare collectionField serviceSecurity parcel dispatching (Cash In Transit)

Ask 4P technical support directly or your dealer to get more information about them.



4 COMMUNICATIONS

DAT400 palm computer allows full connectivity to any device with a RS232 serialinterface in order to:

• locally transfer files from the DAT400 to the host computer and vice versa;• remotely transfer files from the DAT400 to a host computer via modem;• update the DAT400 user application program and operating system (download

procedure, refer to 3.1 Embedded download for details);• print on external printers with RS232 interface;• transfer data via RS232 to/from other external devices, such as the Orion® GPS +

GSM vehicular system.

Refer to 4.1 Communication examples, to have some examples about the hardware andsoftware details for DAT400 connectivity.

4.1 Communication examples

This section describes a number of communication examples, among the DAT400, ahost computer, the DAT400 accessories and other devices. However, otherconfigurations are possible. Please, contact 4P technical support for any special need.

Communication programs (listed in TABLE 2, case 2) together with DAT400accessories allow “unattended communications”, that is the whole file transferprocedure does not require any user activity, improving system reliability and easiness.

4.1.1 Local communications

Local communications apply when the devices are in a short range (few meters)connected without the use of any wired or wireless modem.

4.1.1.1 Local file transfer: DAT400 to Host Computer via RS232 cable.

The following figure shows the connection between DAT400 and the host computer(e.g. the user’s Personal Computer) via RS232 serial cable. The serial cable P/NJ1130/A must be connected to the PC serial port (COM1 or COM2) and to DAT400COM1.

As the connection is RS232, it is advisable only if the distance between DAT400 andthe host computer is less than 15m. For longer distances, use RS485 connections (e.g.,refer to FIG. 27).

RS232 cable connection requires very simple hardware, but it is not suggested when:

• several DAT400s have to be connected to the host computer at the same time andcommunication process must be unattended (refer to FIG. 27 for the alternativeconfiguration);

• DAT400 has to be connected and disconnected very often (several times per hour)(refer to FIG. 25 and to FIG. 26 for the alternative configurations);

• battery charging is also required, because, when the RS232 cable is used, the batterycharger can not be plugged into DAT400 (refer to FIG. 25, FIG. 26 and FIG. 27 forthe alternative configurations).

4.1.1.2 Local file transfer: DAT400 to Host Computer via desktop cradles.

The following figure shows the connection between the DAT400 and the host computer(e.g. the user’s Personal Computer) via P160 desktop cradle. The serial cable (P/NJ1124/A) must be connected to the PC serial port (COM1 or COM2) and to the P160COM1. The P160 charges the DAT400 battery pack and one spare battery at the sametime; it connects the DAT400’s COM1 serial port to the P160’s COM1 one (replica).Therefore, all the considerations about local file transfer between the DAT400 and thehost computer via RS232 cable are applicable.

Loading in protected area

If the password-protected mode is enabled (refer to 3.1), when you press “GO!” button,this window appears:

Fill in the password and press “OK” (e-mail 4P technical support to get the password [email protected]).

DANGER

Loading a file into the protected area is a critical operation. If communication fails forany reason, the product has to be returned to 4P for factory re-programming of theinternal Flash-EPROM.

Normally you never need to download files into the protected area.

In the unlikely event that you need to do the download a file in the protected area paythe maximum attention to the following issues:

• Check that the serial connection is OK before starting the downloading procedure.• DO NOT disconnect the serial connection.• DO NOT ABORT the downloading.• Check that the battery is fully charged.• DO NOT remove battery.• DO NOT turn the DAT400 off incidentally or by purpose.

Refer to “WinLoad4.2, File Loading Utility, User Guide” for details.

5.3.3 Starting download at DAT400 side

There are 2 options to start download at DAT400 side:

• from the Set Up utility;• at DAT400 power on.




5.3.3.1 Starting download from Set Up utility

From Set Up main menu (refer to FIG. 35 System Menu (selecting download and setup),

• press 1 = DOWNLOAD

and the following mask will appear

FIG. 36 Selecting download type

• press 1=CABLE

The downloader procedure will start. Please note that no mask will change on theDAT400.The PC will show the downloader progress by either the status bar (WinLoadxx) or thenumber of transmitted bytes (Pcloadxx, in Ms-DOS operating systems) or ‘*’ (Pcload54in Unix/Linux).

When the downloader procedure is properly completed, your DAT400 applicationprogram will immediately start.

5.3.3.2 Starting download at DAT400 power on.

This method is very simple and it requires that the DAT400 is initially turned off. Youhave just to:

• power on the DAT400. The download will immediately start providing the PC sidehas already been started.

5.3.4 DAT400 program downloading from a data file contained in DAT400 massstorage

The following procedure applies if the executable and downloadable file is contained inthe mass memory. Therefore, in this case, it is not necessary to connect the DAT400with PC.Two mass storage zones may contain that file: they are named “A Zone” or in “BZone”.From FIG. 36 Selecting download type, select:

DOWNLOAD DAT4001= CABLE2= * A * ZONE3= * B * ZONE




2 start download from A Zone3 start download from B Zone

DAT400 will ask you for the relevant Password that is factory set (E-mail 4P technicalsupport to get the password at [email protected]).

FIG. 37 Inserting password

This menu is automatically exited when you type the last Password character and thedownload from the data file contained in the related mass storage zone will start.When downloader procedure has completed properly, your DAT400 applicationprogram will immediately start.

5.4 Set Up

Choosing 2 SETUP from the Main Menu, your DAT400 allows you to modify thecontrast of LCD, with the following mask

FIG. 38 Selecting LCD contrast

where:

OPTION KEY DESCRIPTION

UP <#> increases the LCD contrastDOWN <$> decreases the LCD contrastESC <ESC/NO> selects the default LCD contrastENT <ENT/YES> stores the current LCD contrast value
