Overview

The Door Processor Unit 7910A (DPU-7910A) manages and controls individual access to restricted areas when incorporated into the I/NET access control system. The DPU-7910A is a microprocessor-based control unit that combines data processor, memory, communications, and field inputs. The unit controls up to two doors using four reader inputs, four discrete inputs, two contact inputs, and two relay contact outputs for each door. By processing the input data with programmed information, it controls access into, and exit from an area. It can monitor the status of the door and route this information to selected I/NET workstations and printers. The DPU resides on a sub LAN network controlled by either the 7791 Door Processor Interface (DPI), 7793 Micro Control Interface (MCI), or 7798 I/SITE LAN.

Warning: One of the relay contact outputs for each door is a door strike switch that is intended to provide a failsafe for the software logic. These outputs are not intended to replace a mechanical door interlock for egress. Use of this output in a mechanical door interlock must conform to local fire, life, and safety code wiring and installation requirements. Refer to “Mechanical Door Interlock Wiring” on page 10.

DPU-7910A Features

The DPU 7910A supports a total of 48,000 users. When the DPU is loaded with firmware version 2.1x or earlier, you can assign up to 24,000 users to each of the two doors controlled by the DPU. When the DPU is loaded with firmware version 2.2x or later, you can assign more than 24,000 users (up to 48,000) to a single door as long as the combined number of users for both doors does not exceed the 48,000-user DPU limit. Since each tenant within I/NET can have up to 24,000 users, you must define at least two tenants in order to assign more than 24,000 users to a single DPU door.

The DPU-7910A configuration is controlled by DIP switch settings on the interface board. These settings establish the DPU-7910A's LAN address, LAN baud rate, warm/cold start, translation table use, and LED operation.

Reader SupportThe DPU-7910A can recognize CSI's access control readers including:

✦ I/DISC

✦ Watermark

✦ 26-bit and 32-bit Wiegand

✦ 66-bit Wiegaind (requires DPU firmware version 2.20 or later)

✦ ABA Mag-Stripe

✦ Mag-Tek.

The DPU can be configured to use any of these readers through the I/NET Door Exten-sion Editor (66-bit Wiegand requires I/NET 2000 version 2.x or later). Changing resistors on the DPU allows you to connect low-level drive current readers to the unit. Addition-

Overview Installation Guide

ally, you can assign the anti-passback, first key auto-unlock, and 24-hour access options with the I/NET Door Extension Editor.

MemoryThe DPU-7910A contains 128 KB of memory: 64 KB of EPROM and 64 KB of battery-backed RAM. The DPU provides event buffering, and it stores activity messages that are also protected by the on-board battery backup.

Depending on the firmware version loaded in the DPU, the 64 KB of RAM is allocated as follows:

✦ Fixed allocation (firmware version prior to 2.20):Fixed memory allocation provides storage for up to 100 messages and up to a 24,000-user database for each of two doors.

✦ Dynamic allocation (firmware version 2.20 or later): This provides dynamically allocated storage for varying combinations of up to 5,000 messages (approximately) and up to 48,000 users (up to 24,000 for each of two doors, or up to 48,000 for a single door). Refer to the Access Control chapter in the I/NET 2000 Technical Reference Guide for more information about DPU dynamic memory allocation.

On-board Battery Backup

Caution: This product contains a Nickel Cadmium rechargeable battery. The battery should not be burned or incinerated when disposing of this product.

An on-board Ni-Cad battery (separate from the optional standby battery) maintains the database contents in RAM during a power loss. This power backup of the database allows the DPU-7910A to resume controlled access operation when the power is restored.

Optional Standby BatteryAn optional standby 12 VDC, 4 ampere-hour battery provides power to the DPU-7910A that enables full operation during a power loss. Controlled access continues for the dura-tion of the standby battery life until normal power is restored. The back-up battery system provides up to eight hours of supervised operation during power failures.

A strike power supply can be included to provide battery backup for the door strike and contact shunt outputs when the primary power is lost. This backup battery is in addition to, and separate from, the standby battery that powers the DPU-7910A controller card during a power loss.

CommunicationThe DPU-7910A communicates with the supervised points through shielded, twisted-pair cable. The operating distance between the DPU-7910A and the points supervised or controlled is a maximum of 300 feet (90 m) on an input or output line. The DPI or MCI communicates through the RS485 port using shielded, twisted-pair cable.

Note: Failure to install the system in accordance with the UL requirements is a violation of the UL Listing mark.

3. Repeat steps 1 and 2 for door 2 using TB2 posts 5 and 6.

Installing Supervised Field InputsSupervision may be accomplished on a single Normally Open or Normally Closed contact, or on multiple Normally Open contacts connected in parallel. The contacts may be supervised for line cuts by using a single resistor connected in parallel with the contact. If you want additional supervision for line shorts, an additional resistor connected in series with the contact may be used. The resistor for either shall be 1K ohm, 1⁄4 W, ±5%, or 1K ohm, 1⁄4 W, ±1%. The Resident I/O Points editor of the I/NET Host must be configured for either single resistor supervision, or two resistor supervision. See Figures 3 and 4 for resistor placement.

Mechanical Door Interlock WiringWhen the DPU-7910A door release outputs are used as a part of your mechanical door interlock, you can use the following wiring application.

Warning: Wire in accordance with national and local fire, life, and safety code requirements.

This wiring application uses a magnetic lock and the DPU-7910A door release inputs to energize a strike relay. This relay should be wired in series with a mechanical interlock, for example a Normally Closed contact on a DPST release switch or crash bar (see Figure 6). This provides a logical means, as well as a mechanical means, to break power to the door lock.

Note: It is necessary to provide a mechanical means to break power to the lock, or a mechanical device to release the door, in all access-controlled areas for emergency egress. In UL Listed systems, a UL Listed door release must be used to allow exit during unpowered, emergency egress.

Warning: One of the relay contact outputs for each door is a software door unlock. This is provided for key-read entry and auto-unlock. These outputs are not intended to replace a mechanical door interlock for egress. Use of this output in a mechanical door interlock must conform to local code wiring and installation requirements. Refer to the wiring diagram in Figure 6. (In UL Listed systems, the release switch wiring must be inside the restricted area protected by the DPU-7910AU.)

DP LAN Connections

Note: Stand-alone UL Listed applications do not use LAN connections.

The DPU-7910A can be connected to the DP LAN through an RS485 port (TB4) using shielded, twisted-pair cable (refer to “Specifications” on page 31). Wire the DPU-7910A parallel with the other DPUs on the DP LAN — all the positive lines connect to the COM+ (terminal 1) and all the negative lines connect to the COM– (terminal 2).

Warning: Failure to disconnect power from all interconnected equipment when performing electrical installation may result in ELECTRICAL SHOCK and/or SEVERE BURNS.

1. Connect the negative line to COM– (TB4-2).

2. Connect the positive line to COM+ (TB4-1) as indicated in Figure 7.

✦ Ensure that the sub-LAN cable shield drain wire is not connected to the controller sub-LAN terminal block.

✦ Shield drain wire continuity must be maintained as the sub-LAN cable passes through each controller. Shield drain wires from each controller sub-LAN cable must be twisted together, insulated, and tied back such that wires do not come in contact with ground or any conductive surface within a controller.

✦ Connect the shield drain wire directly to Electrical Service Earth Ground at only one end of the cable (e.g., at the MCI, DPI, or controller).

This optional switch signals the I/NET system whenever someone opens the DPU-7910 enclosure lid. The tamper switch, along with mounting hardware, can be ordered as a separate kit (part number KITSW). Use the following procedure to install the tamper switch connections on TB3.

1. Using two number 4 hex nuts, mount the tamper switch bracket inside the lip of the enclosure, using the two 4-40 × 3⁄8" studs provided just below TB3.

2. Using two number 4 hex nuts, mount the magnet to the two studs provided along the bottom edge of the DPU enclosure door.

3. Connect the switch leads to terminals TB3-7 (TMP+) and TB3-8 (TMP–), located at the base of the DPU-7910A circuit card (see Figure 7).

Power Connections

Connect the primary power, 24 VAC, to the power strip terminals. Use the following procedure to install primary power to the DPU-7910A at port TB3.

Caution: Connect only one device to a transformer. Do not attempt to use the same AC transformer for any sub-LAN device (DPU) and its associated LAN interface device (DPI or MCI). This will result in improper operation of one or both of the devices.

Warning: Failure to disconnect power from all interconnected equipment when performing electrical installation may result in ELECTRICAL SHOCK and/or SEVERE BURNS.

Connecting Power1. Remove the power to the power line at the circuit breaker box.

2. Connect the 24 VAC power input across terminals 1 and 2 of TB3 — located along the base of the DPU circuit card.

3. Connect terminal 3 of TB3 to the Electrical Service Earth Ground wire. The enclo-sure should also be well grounded. Connect the ground line to EGND (TB3-3) as indicated in Figure 8.

4. Restore the power to the power line at the circuit breaker box.

Connecting the Optional Battery BackupThe DPU-7910A has an optional 12 VDC, 4 ampere-hour battery backup to enable oper-ation during primary power failure. Use the following procedure to install the backup battery to port TB3.

Note: In UL Listed systems, the battery backup must be installed.

DPU 7910A 13


Warning: Failure to disconnect power from all interconnected equipment before performing electrical installation may result in electrical shock and/or severe burns.

1. Remove the power to the power line at the circuit breaker box.

2. Place the battery in the DPU-7910A cabinet with the terminals to the front of the cabinet.

3. Secure the battery in place using the battery retaining bracket and hardware.

Grounding Requirements

To ensure proper operation of the controller, it is imperative that the unit be correctly grounded. Depending on the mounting location and mounting method used to install the unit, the controller chassis may not necessarily provide adequate ground for the input power circuit and interconnected sensors/devices: therefore, use the following grounding requirements during unit installation.

Earth Ground

Note: You must establish a proper earth ground connection point prior to connecting ground wires to electrical equipment.

✦ Electrical Service Earth Ground wire must be securely connected to the equipment chassis.

✦ The Electrical Service Earth Ground wire must then be connected to the ground terminal on the controller power input terminal block.

Baseplate Ground

Note: Baseplate grounding requirements apply to all controllers having a baseplate.

✦ Good contact must exist between the baseplate and chassis. Ensure that all mounting screws are tight.

✦ If you suspect that a good ground on the chassis is not present, attach a 12-AWG (3.331 mm2) ground wire from the Electrical Service Earth Ground wire to the baseplate. Attach the ground wire between the PCB and the baseplate, using one of the mounting screws.

✦ If resolving a grounding issue with previously installed equipment, use star-tooth lock washers to ensure a tight connection between the PCB and the baseplate.

LAN Ground

Note: This procedure applies to all LAN and sub-LAN connections.

✦ Ensure that the sub-LAN cable shield drain wire is not connected to the controller sub-LAN terminal block.

✦ Shield drain wire continuity must be maintained as the sub-LAN cable passes through each controller. Shield drain wires from each controller sub-LAN cable must be twisted together, insulated, and tied back such that wires do not come in contact with ground or any conductive surface within a controller.

✦ Connect the shield drain wire directly to Electrical Service Earth Ground at only one end of the cable (e.g., at the MCI, DPI, or a single controller).

Note: LAN connections are not UL tested.

DPU 7910A 15

Setup and Operation Installation Guide

Setup and Operation

The DPU-7910A mounts on an indoor wall surface within area that meets this unit's environmental specifications (refer to “Specifications” on page 31). The DPU address, baud rate, and warm/cold start option must be set on the DPU controller card first. These DIP switch settings are effective upon entering them and reset or cycle the DPU power.

The DPU-7910A connects to two doors. Each has two reader inputs, two contact inputs, and two relay contact outputs. Table 3 identifies these inputs and outputs.

Addressing the DPU-7910A

Set the LAN address (0–31) using DIP switches S2-1 through S2-5 before you “hook up” the communication lines. The LAN address is effective upon entering the information and resetting the DPU. The factory-set address for the DPU-7910A is number 1. The switches are binary, and they contribute their address value to the other switches when ON. The following table presents these values.

Table 3. DPU-7910A Supervised Devices

Equipment Function

Key/Card Reader, I/DISC Reader, or Card Reader with PIN Pad

Key, card, or other form of identification tag used to determine entry and exit authorization through the door. These tags can use CSI proprietary magnetic stripe keys and cards, I/DISC, industry-standard ABA magnetic stripe, proximity, Wiegand, or a multitude of others that provide Wiegand-type output signals.

Supported PIN pad equipped card readers include: Motorola/Indala ARK501 proximity/PIN reader, Dorado 780 swipe/PIN reader, and Hughes Proxpro proximity/PIN reader.

Door Release Switch

Dry contact inputs that are Normally Open (NO) or Normally Closed (NC). When the release button is pressed, the door is released.

Door Sense SwitchDry contact inputs that are Normally Open or Normally Closed. It monitors whether the door is open or closed. It enables the door strike to relock immediately upon door closure.

Door StrikeDry relay contact outputs that are Normally Open or Normally Closed. This contact controls the 12–24 VAC/DC voltage to the door strike.

Door ShuntDry relay contact outputs that are Normally Open or Normally Closed. It can be used to bypass a “door open” signal when the DPU-7910A releases the door.

Switch Value 1 2 4 8 16

16 DPU 7910A

Installation Guide Setup and Operation

For example, when only switch S2-1 is ON, the DPU-7910A address value is 1. When only switches S2-1 and S2-3 are ON, the address value is 5 (1 + 4 = 5). To set the DPU-7910A to Address 31, set switches S2-1 through S2-5 to the ON position.

Reader Inputs

The DPU-7910A provides a common interrupt-driven hardware interface for several different reader types. The reader type must be selected through the I/NET Doors Parameters Editor.

The selection through I/NET of a reader requires a download of the reader type from the host system. Currently-defined readers include the following:

✦ Standard CSI I/NET (key, card, insert, and swipe)

✦ Indala I/NET

✦ 26-bit Wiegand

✦ 32-bit Wiegand

✦ 66-bit Wiegand with or without PIN pad (66-bit Wiegand support requires I/NET 2000 version 2.x and later, and DPU firmware version 2.20 or later)

✦ ABA Mag-Stripe

✦ Watermark Magnetics

✦ I/DISC without PIN pad (PIN pad supported on DPU-7920 only)

When the DPU is used with I/DISC or Wiegand readers (or those readers that deliver a Wiegand-type signal output), the plug-on shunts that are labeled J3–J6 must be moved from the B and C posts (factory default) to the A and B posts. For all other reader types, keep the shunts in the factory-set positions at B and C posts. If selecting a Mag-Tek or low–level drive current reader, the resistors in RS4 and RS6 should also be changed.

Note: You can use different reader types for Door 1 and Door 2. Door 1 uses shunts J3 and J4, and Door 2 uses shunts J5 and J6. Entry and Exit readers on the same door must be the same type.

When using the Mag-Tek (MT211/215) or any other reader with an output signal-level of less than 5 mA, the resistors plugged into RS4 and RS6 should be changed from 1K to 4.7K 1⁄4W 5% resistors (P/N 800475-19). RS4 is used for reader ports 2A and 2B and RS6 is used for reader ports 1A and 1B as shown in Figure 9.

The readers connect to the DPU-7910A through the four RJ45 modular jacks that are located on the right-hand side of the controller card (see Figure 10). Each door can have two readers (i.e., entry and exit). This allows anti-passback operation for both doors. Table 5 presents the ports and their functions.

The RJ45 modular jack provides connections for up to eight signal conductors from the various reader types. When using the CSI Mag-Stripe Key/Card readers and the standard modular reader cables, the reader connection simply plugs the appropriate cable from the desired reader into the appropriate jack. When connecting the DPU to other types of readers, you will typically need to attach discrete signal conductors from the reader to the DPU. Refer to TCON112, CSI Readers Installation Guide for connection information.

DPU 7910A 17


Discrete contacts connect to the DPU reader port through optional breakout boxes. A breakout box provides an eight-screw terminal board for each required reader port. Each breakout box provides terminal board connection support for two readers, and they can be ordered as part of the DPU model number or by the kit designation of part number KITRDRCON. The kit provides a dual-modular RJ45-to-terminal assembly with adhe-sive backing, which is suitable for installation in the DPU enclosure. Two 8-inch modular cables provide connection of the breakout box to the reader ports you select. When three or four reader connections are required, you can install up to two kits.

The eight signal conductors from the DPU RJ45 port are presented on the eight screws (numbered 1 – 8). Table 6 identifies the function of the signals with the various reader types.

LED OperationThe DPU-7910A provides two LED control outputs for each connected reader. These control outputs operate with the discrete LEDs that are provided by many readers.

Two-color LED Control

For dual-color operation, the DPU requires a discrete control-wire connection to each of the two colored LEDs. Additionally, the LED DPU control signal uses the following logic:

✦ Positive: 0 volts = OFF and 5 volts = ON

✦ Negative: 0 volts = ON, 5 volts = OFF

The Wiegand readers typically present the cathode of the LED for control, while CSI and many others present the anode. Using the Door Extension Editor in the I/NET system, select common anode for Wiegand and common cathode for most other readers.

Note: With single LED Wiegand readers, connect the LED wire to Terminal 7 of the Breakout Box. This enables the LED to follow the state of the strike/shunt outputs of the DPU (i.e., secure/unsecure state of the door).

Note: LED polarity is configurable using the Door Extension Editor (either positive or negative logic).

The LEDs may be a color other than red or green, but the output for these LEDs is still referred to as red or green LED output.

5

CLOCK With the Mag-Stripe readers, this conductor carries the CLOCK signal from the reader. This signal normally rests at 5 volts, but pulses to 0 volts while the data on conductor number 3 is valid. This signal is called STROBE by some ABA reader manufacturers and CLOCK by others.

DATA-0With Wiegand readers, this conductor carries the DATA-0 signal from the reader. The signal normally rests at 5 volts, but pulses to 0 volts upon the detection of logic 0 bits in the Wiegand data sequence.

6 Red LED

This signal drives a red LED located in the reader. The actual color of the LED is not critical, except to note that future references to red LED function/operation in this document refer to the LED connected to this conductor.NOTE: LED polarity is configurable using the Door Extension Editor.The DPU momentarily displays the red LED when a key/card was successfully read, but not authorized to release the door. The red LED flashes for a couple of seconds when the DPU detects a key/card entry, but it does not successfully read the data from the reader (i.e., a retry is necessary).

7 Green LED

This signal drives a green LED located in the reader. The actual color of the LED is not critical, except to note that future references to green LED function/operation in this document refer to the LED connected to this conductor.NOTE: LED polarity is configurable using the Door Extension Editor.The DPU momentarily displays the green LED when a key/card was successfully read, accepted by the DPU, and authorized to release the door. The green LED control signal also flashes for a couple of seconds when the DPU detects a key/card entry, but it does not successfully read the data from the reader (i.e., a retry is necessary). The double-flash function (red and green LED) indicates a bad read condition (i.e., some readers have only one LED).

8 DC Ground This conductor connects the DC signal ground from the DPU to the reader.

Table 6. Reader Signal Breakouts (Continued)

Terminal Number Signal Function

20 DPU 7910A


The red LED output indicates two conditions. The red LED output is placed in the ON state for one second to indicate an unauthorized key/card entry. The red and green LED output flashes five times within one second to indicate that a key/card was detected, but not read successfully.

With all readers, the green LED output is used to indicate the state of the strike/shunt outputs from the DPU (i.e., the secure/non-secure state of the door). The green LED output is continuously in the ON state while the strike is de-energized (i.e., door is open).

The green LED output also indicates a bad key/card read condition. A bad read causes both the green and the red LED outputs to flash for one second. This double-flash LED displays for readers that provide only one DPU-controlled LED. This guarantees that a user always receives visual feedback and prompts them to re-enter the key/card if neces-sary.

Three-color LED Operation

The Dorado 780 swipe/PIN reader makes use of three LEDs as follows:

✦ Red – This LED is labeled “Swipe Card.”

✦ Yellow – This LED is labeled “Enter PIN.”

✦ Green – This LED is labeled “Open Door.”

Control for the three LEDs is provided through two lines labeled “Control A” and “Control B.” The operation of the LEDs is shown in Table 8. The unique algorithm used to control the three LEDs is activated by a DIP switch setting on the DPU. For Door 1, set DIP switch S2-11 to ON. For Door 2, set DIP switch S2-12 to ON.

DPU 7910A 21


You can set the LED Polarity for each door to either “Anode” or “Cathode.” Depending on the selected setting, the DPU will operate as follows:

✦ Cathode – This setting causes the DPU to provide three-color LED control to both the entry reader and exit reader. Use this setting if both readers are Dorado 780 swipe/PIN readers.

✦ Anode – This setting causes the DPU to provide three-color LED control to the entry reader and two-color LED control to the exit reader. Use this setting when only the entry reader is a Dorado 780 swipe/PIN reader.

CSI Key/Card Reader SupportTo assign the controller in I/NET, select TRACS to identify the reader type. The DPU-7910A provides a direct interface to the CSI magnetic-stripe key/card readers. This reader provides a security advantage over other mag-stripe readers in that the cards and keys cannot be duplicated with standard encoding equipment.

I/DISC Reader Support

Note: The DPU-7910A does not support the use of a PIN pad in conjunction with an I/DISC reader. Therefore, this DPU will ignore the setting of the “PIN pad” option in the Door Extension Editor when you define the reader type as “I/DISC.”

Select I/DISC from the Door Extension Editor in I/NET to assign this reader type to a door. The DPU-7910A supports up to four I/DISC readers. The CSI I/DISC button is a read-only memory device that replaces key/cards for the DPU-7910A. This method of identification provides a higher degree of security and reliability than other device types. The I/DISC buttons consist of a small button-shaped device containing a micro-electric circuit, which includes a communication interface and other unique ID features.

All readers should be installed in a location that is convenient to the intended point of entry. It should also be protected from the weather by a shield or hood when located outside. When using the I/DISC reader outside, we recommend that you periodically (every month or two) clean the reader/probe surface area with a metal cleaner/protectant to remove contaminants or moisture-related corrosion. A cleaner/protectant (i.e., WD-40) can be used for this purpose.

The LED and sensor pigtails connect to a 24 AWG (0.206 mm2) shielded, twisted-pair cable of a CSI breakout box. The DPU-7910A connects to the breakout box using RJ45 terminated cable.

Wiegand Reader SupportThe DPU-7910A lets you directly connect readers providing a Wiegand interface. The Wiegand data stream formats supported by the DPU-7910A and selectable within the Door Extension editor of I/NET are:

✦ Wiegand 26-bit — The 26-bit Wiegand format is a standard used by many reader/card manufacturers. This bit pattern is called the 2601 format by Sensor Engineering and is available to the user directly from them.

✦ Wiegand 32-bit — Since the CSI 32-bit format is a proprietary format, other 32-bit cards and keys cannot be used with CSI readers using 32-bit Wiegand format, and CSI 32-bit format cards and keys cannot be used in other manufacturer’s readers.

22 DPU 7910A


Cards with the CSI 32-bit format are available only from CSI. This limited format, and the CSI-controlled site number field, provides an additional level of user secu-rity.

✦ Wiegand 66-bit (requires I/NET 2000 version 2.x and later, and DPU firmware version 2.20 or later) — The CSI 66-bit format is a proprietary format that currently supports the use of the AES Prodata smart card reader.

The group of readers capable of producing these types of output formats include most of the technologies (mag-stripe, proximity, biological, voice, etc.) as well as the Wiegand technology reader from Sensor Engineering. Use the Door Extension Editor within I/NET to select either the 26-bit, 32-bit, or 66-bit Wiegand format when assigning this type of reader to the DPU.

Data from the Wiegand reader (or other device producing Wiegand output) is presented through a two-wire interface, plus a ground reference. The two-signal conductors provide Data-0 and Data-1 lines that typically provide a TTL-level, active low pulse. Some two-signal conductor devices use an open-collector output. A pulse is generated on the respective line (logic-0 or logic-1) for each bit in the 26-/32-/66-bit pattern.

The DPU-7910A accepts a minimum pulse width of 10 microseconds and a minimum time between pulses of 75 microseconds. This complies with the minimums specified by Sensor Engineering. However, other devices that simulate Wiegand output, usually through microprocessor code, must be evaluated for compliance.

One of the interface difficulties associated with the use of the Wiegand cards revolves around the differences in the card encoding styles A and A1 and the associated right-hand and left-hand insertion readers. The standard A1 card used for swipe readers reverses the bit pattern when used in an insertion reader (style A1). This causes the least significant bit (LSB) to be read first instead of the most significant bit (MSB).

Only the MSB-first sequence is supported when using the 66-bit Wiegand data format. When reading 26- or 32-bit Wiegand data format, the DPU-7910A supports either an MSB-first or LSB-first sequence. Inversion of the 0 and 1 bits is also supported with the 26-bit and 32-bit data formats so long as you have not enabled translation tables (i.e., you have not placed DIP switch 7 in the ON position).

The DPU-7910A provides a user-tolerant interface by automatically detecting an inverted bit pattern and adjusting the read process, as required to decode the key data correctly. This detection is based on the examination of the 26-bit or 32-bit Wiegand bit pattern and does not require any action on your part:

Indala Proximity Reader SupportThe DPU-7910A supports Indala Proximity readers, CSI model numbers PR103, PR-105, PR-110, PR-112, PR-120, PR-122 and remote antennae ARE-142. These proximity readers produce standard Wiegand output, and they are recognized by the I/NET soft-ware as Indala proximity readers.

Watermark Reader SupportThe DPU-7910A supports two Watermark Magnetics card readers developed by Thorn Secure Science International (model numbers 1305LO and 1306LO). Data from the reader is communicated through a four-wire interface using power, ground, data, and clock (additional 3-wire, if LED is used).

DPU 7910A 23


ABA Standard (Track 2) InterfaceThe DPU-7910A can receive standard TTL-level Data and Strobe lines from an ABA Mag-Stripe or Mag-Tek (model numbers MT-211 and MT-215 readers). The DPU-7910A uses standardized data recovery and interpretation, which is defined on the ABA track (Track 2 - center track) of a magnetic-stripe card. The ANSI/ISO standard (ANSI x4.16-1983/ISO 3554) defines this format. Using the Door Extension Editor, select ABA_115 for a 16-digit format or ABA_85 for a 12-digit format. Both allow an unlimited number of trailing digits.

Compatibility with standard ABA-encoded cards facilitates the use of many affordable off-the-shelf mag-stripe readers and cards. The data is encoded on the mag-stripe as a sequence of 5-bit hexadecimal digits (4 bits, plus odd parity on each digit). The ABA format is described in ANSI x4.16.

Discrete Inputs

If no door is assigned to the DPU, you can assign the discrete inputs as supervised or non-supervised DI or DA points. The points are designated through the I/NET software.

Addressing the InputsThe DI or DA input point addresses are presented in Table 9 and Table 10.

Tamper InputThe DPU-7910 has an input (TB3 7–8) that connects an optional, internally mounted, enclosure-door tamper switch. This switch alerts the I/NET system when someone opens the enclosure door. The address for the Tamper input is LLSSPP08, and is a DA or DI point.

24 DPU 7910A


Supervised StatusThe discrete inputs can be designated as supervised (one or two resistors) or non-super-vised. To configure the input, modify the supervised parameter in the I/NET Resident I/O Points Editor of the DPI/MCI. If using I/NET version 3.10 through I/NET version 4.21, DIP switch S2-7 on the DPU is not used and must be in the OFF position.

Battery InputTB3-1 is a dedicated-battery status input. The optional battery monitor enables the DPU-7910A to alert the I/NET system when the primary power is lost. The battery status input address is LLSSPP09, and it is a DA or DI point.

Outputs

The DPU-7910A has two outputs on one 12-point plug-on block (TB1). These outputs consist of four Form C contacts. Two contacts are assigned to each output. The outputs are DO points, and they are addressed as indicated in Table 11.

If assigned to doors, the first contact set is typically wired to the door lock/strike/bolt. The other contact set is wired to a third-party alarm system for alarm shunting. Refer to “Connecting the Door Strike and Contact Shunt Output” on page 9. Door assignment is achieved by declaring the point internal and assigning a door extension to the point through I/NET.

If the points are not assigned to doors, they are external and will be processed like any I/NET DO point. However, they cannot be pulse-width modulated (PWM) analog outputs.

Start-up Sequence Conditions

The DPU-7910A can execute a cold start or a warm start depending upon the DIP switch S2-8 setting. The normal configuration and factory default is a cold start. The term warm and cold start refers to the microprocessor start-up sequences that are initiated when the red reset button is pressed or when the power is cycled to the controller without full standby battery backup. Losing primary AC power to a battery-backed DPU will not cause a warm or cold start, because the DPU continues to operate through a power outage for up to eight hours.

Cold StartA cold start sequence clears all memory (i.e., event-history collection, program data-base), reads and interprets all switch settings, sets the date and time to zero, and secures and/or locks all doors. A cold start occurs when you press the red reset button or cycle

the power with the switch S2-8 in the ON position. Furthermore, the DPU will reset itself upon the detection of a memory loss when the power is OFF for more than eight hours. No key/cards can open a door until the DPU is downloaded by the I/NET host computer.

Note: In order for the host to detect a “Memory Lost" message from the DPU, the eighth mask of group 1 in the Host Configuration Editor must be in the “ON” or “CLOSED” position. Failure to set it will result in no automatic downloading to the DPU.

It is recommended that switch 8 be put in the OFF or OPEN position once initialization and start-up are complete.

Warm StartA warm start sequence causes the DPU to generate reset messages, read and interpret all the switch settings, and set the clock to 00:00 (midnight) and the date to 00/00/00. During this period, only keys with 24-hour/7-day access can open the doors that are controlled by the affected DPU. This condition persists until the I/NET host computer broadcasts the correct time to the DPU, which usually happens once each minute.

The DPU performs a warm start when the unit is reset (or the power is cycled to a non-battery backed unit), the cold start switch (S2-8) is OFF, and the program detects no memory loss.

Setting Communications

The LAN connects through an RS485 serial communication interface at port TB4 at 9600 or 19200 baud. It has a maximum distance of 5,000 feet through shielded, twisted-pair cable. See Figure 1 for location.

Baud RateThe DP LAN 9600 baud rate is set by placing the DIP switch S2-6 to off. The DIP switch setting is shown in “DIP Switch S2 Settings” on page 28. This switch must be set for 9600 baud.

Monitoring for Primary Power Loss

You can monitor the 7910A for primary power loss while using the optional battery backup. Using the editors in the I/NET 7700 system you can program the 7910A with the following parameters.

For the station address of the 7910A, use bit offset 09 as an external DA point. Define state description for this controller to include normal state (PWR) = 0, and loss of primary power (BAT) = 1. Whenever the primary power goes OFF, this point advances into the alarm state.

Note: This function does not work when the backup battery option is not used.

LED StatusThe DPU-7910A has three status LEDs on the interface board as shown in Figure 1.

26 DPU 7910A


✦ The first LED (TX) is red, and it flashes when transmitting data.

✦ The second LED (RX) is green, and it flashes when receiving data.

Note: These LEDs should flash when they are connected to an active I/NET system. If the green LED does not light up, there may be a line/cable problem. A constant illumination of the green LED indicates a possible polarity problem on the cable or a fault in the host computer.

✦ The third LED (STATUS) is red. and it is Normally On when there is power and the DPU-7910A is operating correctly. If the unit is running on full-standby battery backup power, it flashes ON and OFF at a one-second interval.

DPU-7910A Stand-alone

The DPU-7910A can operate in a stand-alone mode when communication with the host is severed. The DPU-7910A retains its programming and processes access requests from the door readers. It continues to store event messages until the communication is restored to the host. When the DPU is loaded with a firmware version prior to 2.20, it provides a fixed allocation of memory for storing up to 100 messages. When the DPU is loaded with firmware version 2.20 or later, it provides dynamically allocated storage for up to 5,000 messages (approximately). If the stored messages exceed the allocated memory buffer, the most recent messages are saved and the oldest are discarded.

When the DPU-7910A loses communication with the DPI, MCI, or I/SITE LAN, it retains the programming from the time of the loss. Any anti-passback designated doors that are controlled by the DPU-7910A will continue to function as programmed. The Manual Unlock function is disabled until communications are re-established with the host.

If a power loss accompanies the communication loss with the DPU-7910A configured to cold start, all programming is cleared, the clock resets to midnight, the date resets to zero, and no key/cards can open the affected doors. Once the DPI, MCI, or I/SITE LAN re-establishes communication with the DPU-7910A, the host downloads the DPU and normal operation resumes (if group 1/mask 8 has been set in the host and DPI, MCI, or I/SITE LAN). If a power loss accompanies the communication loss with the DPU-7910A configured to warm start, the clock and date resets and normal operation resumes.
