1INTRODUCTION

1.1 PURPOSEThis document is the specification for communication between the LH 750 Workstation and a host computer. The functionality will remain backward compatible. This document is intended for use by software engineers needing to either maintain or modify the operation of the LH 750 Workstation Host Communications.

This document describes the transfer of data from the LH 750 Workstation to an LIS/HIS computer in the following formats:

r STKS 1G.1 + Retics

r LH 750 Workstation: host communication protocol which supports transmission of CBC, DIFF and Reticulocytes parameters for samples and control runs as well as collated sample runs. This format is an extension of the STKS 2A and 3A formats.

The LH 750 “STKS 1G.1 + Retics” format is provided for use with existing STKS™ and MAXM™ interfaces. Due to the LH 750 Workstation’s new features and enhancements, STKS and MAXM instrument formats are not completely supported (see details in following sections).

PN 4277303B 1-1

INTRODUCTIONPURPOSE

2HARDWARE INTERFACE

The system is equipped with a Host 1 connector on the rear of the LH 750 Workstation that lets the system interface with a host computer via a Standard EIA-type 25-pin connector and uses EIA Standard RS-232-C signals. This is a Data Terminal Equipment (DTE) configuration.

The LH 750 Workstation/Host communications uses only the following signals:

The LH 750 Workstation is the DTE, by RS-232 standards, which explains the RTS/DTR pin-outs. Whether the HOST is a DTE or DCE will determine its use of CTS/DSR or RTS/DTR. A DTE HOST requires the use of a NULL MODEM Cable.

Note: Pin number 5 CTS must be active for LH 750 Workstation to send any transmissions. If the host computer does not support the above hardware handshake lines, it will be necessary to connect pin 4 to pin 5 and to connect pin 20 to pin 6.

2.1 HARDWARE HANDSHAKEDuring a transmission, the host logically raises CTS to allow the LH 750 Workstation to send data and logically lowers CTS to prevent the LH 750 Workstation from sending data.

Note: If CTS is lowered to hold off the LH 750 Workstation host transmission, it must be raised again within the LH 750 Workstation time-out period. If CTS is not raised within the time-out period, the LH 750 Workstation transmission to the host will time-out and reset, ready for the next transmission.

3COMMUNICATION PARAMETERS

3.1 COMMUNICATION PARAMETERSThe LH 750 Workstation allows the user to configure the following communication parameters on the Host Computer Definition screen. These parameters include communication modes, as well as parameters enabling the transmission of graphic data.

3.2 COMMUNICATION PROTOCOLSThe transmission specification consists of data-link (low level) and presentation (high level) protocols. Data-link protocol provides the means of transmitting data without any regard to actual information. Presentation protocol describes the actual information and its format.

Low Level ProtocolThe Host Low Level Communication Protocol will be supported by all formats.

High Level ProtocolThe High Level Communication Protocols currently supported are the “STKS 1G.1 + Retics” and “LH 750 Workstation”. The High Level Communication Protocol is selected using the compatibility field.

Note: To satisfy the host communication requirements, the receiver MUST parse for all of the data.

DO NOT ASSUME FIXED OFFSETS

Table 3.1 lists the communication parameters available by format.

PN 4277303B 3-1

COMMUNICATION PARAMETERSTIME-OUT

3.3 TIME-OUTThe time-out value determines the amount of time the LH 750 Workstation waits for a response from the host before retrying to send data to the host. The LH 750S Workstation continues to transmit at the time-out intervals until the host successfully receives the data.

The time-out values are 30, 60, and 90 seconds. The default value is 90 seconds.

3.4 BAUD RATEThe following baud rates are supported: 2400, 4800, 9600, 19200 and 38400.

Note: The minimum recommended baud rate is 2400 for non-graphic transmissions and 9600 Baud for graphic transmissions.

3.5 DATA BITSHost Communication can be configured for 7 or 8 bit mode.

3.6 PARITYOdd, Even, and Off (None) parity modes are supported. Odd parity is the default value.

3.7 STOP BITSNone, 1, or 2 Stop Bit modes are supported. The default value is 2.

3.8 HANDSHAKEThis option determines whether or not the LH 750 Workstation looks for a handshake from the host computer. See Heading 4.1, Data-Link, for additional information.

3.9 BLOCK SIZEThe LH 750 Workstation/Host Communications support block sizes of 128 and 256 bytes. The default value is 256 bytes.

3.10 GRAPHICSThe LH 750 Workstation allows DIFF and Retic graphic transmission if the compatibility format selected is the LH 750 Workstation format.

Table 3.2 lists the graphic items that can be enabled or disabled for the corresponding test based on the current compatibility format and report profile selected.

P/N 4277303B 3-2

COMMUNICATION PARAMETERSCOMPATIBILITY 3

3.11 COMPATIBILITYThis option determines which transmission format is used by the LH 750 Workstation to send results to an LIS/HIS computer. The Host High Level Communication Protocols supported are: “STKS 1G.1 + Retics” and “LH 750 Workstation”.

3.12 SPOOLERTransmissions to the Host are spooled before sending. When a transmission is sent to the Host, it will be kept on the Spooler and resent until the Host acknowledges that the transmission was successfully received. If the Host is offline when Transmit To Host is enabled, all transmissions intended for the Host will be kept on the Spooler until the Host comes online or the Host Spooler is cleared.

3.13 CLEARING THE SPOOLERSelect the Clear button in the LIS folder on the System Run Configuration screen to clear all spooled transmissions intended for the Host. It should be remembered that new transmissions to the Host will still be subsequently spooled. See Section 3.15 to disable host communications and hence the host spooler.

3.14 REPLACE NULL BY SPThis is no longer an option because NULL characters are not included in the transmission buffer.

3.15 DISABLING HOST COMMUNICATIONSSelect the Disable button in the LIS folder on the System Run Configuration screen to disable all auto transmissions from the LH 750 Workstation to the Host. This will not affect manual transmissions or transmissions from the Host to the LH 750 Workstation.

3.16 ENABLE VALIDATION CODESThis checkbox enables the codes used to identify the validation status of individual test requests on a sample as detailed in Conditional Flags Group Fields under AutoValidation in Chapter 4. If “Enable Validation Codes” in System Setup - [Communications] is checked (default), the individual test group validation status will be transmitted. Applied only to LH 750 format.

4LH 750 WORKSTATION TO HOST COMMUNICATIONS

4.1 DATA-LINKA sample transmission to the Host consists of one or more framed data blocks. See Data Block Structure below. All transmitted data bytes are ASCII characters. All numeric values are ASCII representations of hexadecimal numbers. Hence, for example, the number FF (hex) is represented by the two ASCII bytes "FF" (46H, 46H). The first two bytes of the transmission are the number of blocks to be sent, in ASCII, followed by transmission of data blocks (see format below).

The final block will be padded with ASCII spaces (20H) to fill a whole block.

The LH 750 Workstation supports “full software handshake” and “no software handshake” protocols.

Full Software HandshakeThe LH 750 Workstation sends the following control characters plus data and expects the indicated host response:

Up to 255 blocks of data can be sent. The actual number of blocks sent is specified by the two-byte ASCII Block Count.

Software Handshake ActionIf the host NAKs a data block, the block is retransmitted. It is up to the host to determine how many times it retries receiving a NAKed block before aborting. Typically, the Host will NAK a datablock if the current block number is incorrect(e.g. out of sequence), the Host’s calculated CRC does not match the transmitted block’s CRC or block framing is not recognized as correct.

A SYN sent by the Host after a block has been transmitted by the LH 750 Workstation forces the Workstation to retransmit all data starting with the first block. This does not include the

LH 750 WORKSTATION TO HOST COMMUNICATIONSDATA-LINK

initial SYN and block count. It is up to the Host to determine under what conditions to transmit a SYN.

The LH 750 Workstation continues to send the same sample transmission until the Host accepts it entirely (ACKs each block). To abort a transmission, the host must ACK each block of the transmission and discard it locally.

No HandshakeIf “Handshake” option is disabled, the protocol ignores all hardware and software host hanshake responses. In addition, in the No Handshake mode, the LH 750 Workstation does not send a SYN prior to transmitting the data. CTS is always used to indicate that a Host is MS and turned on.

Data Block Structure

Each data block is framed with a Start Of Text(STX = 02H) and an End Of Text(ETX =03H) control character.

The next two bytes after STX have the Current Block Sequence Number(BLK NBR) in ASCII starting with the number 1(MS byte = 30H, LS byte = 31H, to give ‘01’) for the first block. The block number of the last block must equal the Block Count sent at the beginning of the transmission.

Every data block will have either 128 or 256 bytes (whichever is chosen). If there is insufficient data to fill a block, it will be padded with space characters (last block transmitted).

The CRC for the block’s data is calculated by the workstation and sent as the last four bytes of the block before the ETX in the ASCII format shown above. The Most Significant Byte (MSB) is generated as a Most Significant and Least Significant ASCII character (MS and LS CHAR). The same is true for the Least Significant Byte (LSB).

The algorithm used to calculate the CRC for each block is a modified CCITT CRC16. CRC is only calculated on the data bytes.

Chapter 7 details the CRC algorithm and includes application notes for implementing the algorithm in both C and assembly language.

4.2 1G.1 + RETICS FORMAT

Message StructureThe Presentation deals with the high level format of the message. The data bytes of the transmission blocks, when collected together, exhibit the following high level format.

PreambleThe preamble marks the beginning of a message.

Group

The DC1 (11H) character marks the beginning of a Group. There is no relationship between the order in which the groups are defined in the following sections and the order in which they appear after the preamble. Groups will never be omitted.

Each Group contains a DC1 (11H) character, marking the beginning of the section, a two character field count and a variable number of fields each ending with a CR (0DH) and an LF (0AH).

Note: When there are no data for a Group, the Group will appear as follows:

Field CountEach Group has a Field Count which identifies the number of fields contained within the Group. Valid field counts can be from 0-255. The field count uses two characters to give the ASCII representation of the hexadecimal value.

The field count will reflect the total number of fields transmitted within the Group. The field count will always be the sum of CR/LF pairs within the Group minus one.

A field may have a variable length tag preceding the data separated with one or more SP (20H) characters. The data portion of a field will only contain ASCII characters in the range of 20H to 7EH inclusive. Chapter 6 tabulates the valid ASCII characters. Fields are separated by a CR (0DH) and an LF (0AH) character.

Note: A field's position within a Group must not be used to identify it. Fields within a Group may appear in any order or may be omitted. The CR/LF should be used to find a field and the Tag used to identify it.

The syntax for the Data Format of a field is:

Postamble

The postamble marks the end of the current message. There are 16 groups defined in the current implementation of the “STKS 1G.1 + Retics” format. Future revisions may include additional groups. Any future additions will not disrupt the numbering of the groups as presently defined.

Group Definition

Table 4.2 lists the groups supported by the 1G.1 + Retics format.

A - Alpha characters (a..z and A..Z and space) or (61H..7AH and 41H..5AH and 20H)

N - Numeric characters (0..9 and + - .) or (30H..39H and 2BH 2DH 2EH)

X - Printable characters (20H..7EH)

Sep - Separator one or more SP characters

SP Space (ASCII 20H). Please note that all field transmissions will include a SP between the tag and data format (this will be implied in the following sections), as illustrated below:

Message StructureThe Presentation deals with the high level format of the message. The data bytes of the transmission blocks, when collected together, exhibit the following high level format.

Preamble: The preamble marks the beginning of a message.

Transmission Identification:

The ASCII character "S" marks the beginning of the transmission.

TRANSMISSION TEST COUNT defines the number of tests that will be transmitted in this particular transmission. Not all Test Types are sent in all transmissions.

Each Transmission Test is identified by the order in which it appears after the preamble. The transmission test will never be transmitted out of order.

The Transmission Tests are up to 32 characters long. Table 4.18 lists the available Transmission Tests and Test IDs by Test Type.

Currently only manually entered data is transmitted.

Test Identification:

The ASCII character "T" marks the beginning of a test identification.

TEST ID, see Table 4.18.

GROUP COUNT defines the number of groups of data in this particular TEST Identification.

Group:

The ASCII character "G" marks the beginning of a group. A group follows the test identification fields.

GROUP NUMBER defines the group number. See Group Definition.

FIELD COUNT defines the number of fields in a particular group. See Field Count.

FIELD defines a field within a group. See Fields.

Note: When there is no data for a Group, the Group will not be sent.

Test Type Count:The transmission identification section has a Test Type Count that identifies the number of tests contained within the transmission. Valid test type count can be from 0-255. The test type count uses two characters to give the ASCII representation of the hexadecimal value.

Group Count:Each test identification has a Group Count that identifies the number of groups contained within the test. Valid group counts can be from 0-255. The group count uses two characters to give the ASCII representation of the hexadecimal value.

Group Number:Each group identifier has a Group Number that identifies the group number contained within the group identifier. Valid group number can be from 0-255. The group number uses two characters to give the ASCII representation of the hexadecimal value.

Field Count:Each Group has a Field Count that identifies the number of fields contained within the Group. Valid field counts can be from 0-255. The field count uses two characters to give the ASCII representation of the hexadecimal value.

Fields:Each Group is made up of variable length fields which may or may not be padded with SP (20H), or HT (09H) characters. A field may have a variable length tag preceding the data, separated by one or more SP (20H), or HT (09H) characters. Please note that all field transmissions will include a SP between the tag and data format (this will be implied in the following sections), as illustrated below:

The data portion of a field will only contain ASCII characters in the range of 20H to 7EH inclusive. Heading 6.2, VALID HOST COMMUNICATIONS ASCII CODES identifies the valid ASCII characters. Fields are separated with a CR (0DH) and an LF (0AH) character.

Note: A field's position within a Group must not be used to identify it. Fields within a Group may appear in any order or may be omitted. The CR/LF should be used to find fields and the Tag used to identify it.

ALL FIELDS ARE OF MAXIMUM 32 CHARACTERS LONG UNLESS OTHERWISE NOTED.

The following abbreviations are used to describe the fields:

**The possible Conditional flags generated on the LH 750 Workstation are:

AutoValidation:

The auto validation flags show the validation status of test requests for a sample on printouts and within the results transmission. A functional example of the validation codes is described below.

A specimen is run in CDR mode with a CDR report format requested. Suppose results are acceptable for CBC and Retic, but not for the Diff (e.g., a Decision Rule fails, such as “If Blast [suspect flag], Perform Manual Diff”).

Note: The configuration of the Workstation affects the validation messages and codes.

The CBC and Retic test groups are AUTOVALIDATED, but the Diff group is NOT VALIDATED. There are two ways to indicate this. A conditional text message SAMPLE NOT VALIDATED would be transmitted. Additionally, validation codes C AV, R AV, D NV indicate the status of the individual test groups. The Diff can later be validated manually, resulting in SAMPLE VALIDATED, C AV, R AV, D V.

It is possible through use of the report format to have validation messages based on the report profile (report format). For example, using the scenario above, if a CBC report profile was requested, validation would be based solely on the results of the CBC group. For a complete explanation, refer to the LH 750 Workstation on-line help.

4.4 HOST PARSING OF TRANSMITTED DATACoulter reserves the right to make additions, deletions, and/or change the order of parameters in future releases. However, if the communications protocol is adhered to as specified in this document, future releases will not require reprogramming on the part of the host.

We do not guarantee the appearance of any particular parameter. Neither do we guarantee any particular order to the transmitted data. This ensures that any program written to parse an existing transmission format will not have to be restructured if it is designed properly.

Note that each information item is an ASCII character string. Because of delimiters, field terminators and so on, these information strings may be extracted from the transmitted data block without having to identify the strings at that time.

5HOST TO LH 750 WORKSTATION COMMUNICATIONS (HOST ToDo LIST)

5.1 DATA-LINK

ProtocolThe LH 750 Workstation requires full handshaking to receive data. The protocol is similar to that used for LH 750 Workstation to Host transmissions with the SYN character replaced with the ENQ character.

The data is transmitted as a sequence of up to 255 blocks of data of 256 [or 128] bytes each. Generally, these blocks contain 256 data bytes each, but due to the unique needs of differing hosts, the system is configurable to allow shorter blocks with 128 data bytes. The final block must be padded with ASCII spaces (20H) if it has less than the number of data bytes necessary to complete.

HOST TO LH 750 WORKSTATION COMMUNICATIONS (HOST ToDo LIST)DATA-LINK

The LH 750 Workstation ACKs or NAKs each block sent by the Host. If the LH 750 Workstation NAKs a block, the Host must retransmit that block. If the Workstation NAKs the same block 3 times in a row, the Workstation aborts and is then prepared to receive the next transmission. If the LH 750 Workstation sends an ENQ after the reception of any block, the Host must retransmit all blocks starting with the first, but should not resend the initial ENQ character. Some common reasons why the LH 750 Workstation would NAK a block are: bad block sequence number, incorrect block byte count, CRC mismatch, etc. If the Data Link transmission successfully completes, the LH 750 Workstation then transmits a DLE character followed by a single ASCII character indicating whether the transmission is accepted or rejected at the presentation level. The ASCII characters following the DLE are listed below:

The following demonstrates the above protocol:

Host Computer (SENDER) LH 750 Workstation (RECEIVER)

INTRO FIELD: DE Delete

DE in this field is a command by the host to delete one or more test entries in the LH 750 Workstation ToDo List. See Section 5.4, Delete Message, for a specification for this function.

5.3 MESSAGE DEFINITIONTable 5.1 lists the fields and the format to which they apply. The table also identifies fields that require data transmission in another field in order to be included in the test request. If data is not in the associated field, the LH 750 Workstation ignores the field. For example, if a Patient ID is not transmitted, the LH 750 Workstation ignores any data included in the Patient Last Name field.

After the Table is the list of possible fields, their field width and the appropriate ASCII Tag to be used for transmission.

A field will have a variable length TAG preceding the data separated by one or more SP (20H) or HT (09H) characters. A field tag must be transmitted with data. If a field tag is transmitted without data, the Workstation rejects the whole sample request. If an invalid or unrecognized tag is transmitted, the LH 750 Workstation will ignore the field and go to the next field provided that the field to be ignored has the correct field format (i.e. is terminated by a CRLF).

5.4 Delete MessageWhen the Intro Field of a ToDo List upload from the host contains the Operation string “DE” (see page 5-77), the host has requested the deletion of one or more entries from the LH 750 Workstation ToDo List. The LH 750 Workstation allows deletion of preassigned test orders from the ToDo List by the host according to;

Patient ID

Sample ID Number

Cassette Position

Test Type

The Sample ID, Cassette Position and Test Type are part of the Test Field. The formats for the Patient ID and Test fields are described in 5.3 Message Definitions. The Patient ID and Test field are the only fields of the message definition section used in the Deleted Function. All others are ignored and need not be sent.

In the Deleted context, an ID or TS Tag followed by a CRLF will be interpreted as an empty Patient ID or Test Field.

If the Patient ID field and the Test field are empty, the Workstation deletes all entries from the ToDo List.

According to the above definition, these fields are empty when they have the following form:

It is possible for a pre assignment to be made to the ToDo List that has no Patient ID. If the host requests deletion of this pre assignment, or some part of it, the transmission of the deletion request must contain no Patient ID field. Note that this is not the same as an empty Patient ID field. No field with an ID tag should be sent. See example 10.

On page 5-83, the Data Format of the Test field is given as “TEST,TUBE ID, CASS/POS” or “TEST,TUBE ID,” or “TEST,CASS/POS”. The TUBE ID here is the SAMPLE ID. The commas

Patient ID Field: I D CR LF See Pages 5-5 & 5-9

Test Field: T S CR LF See Pages 5-5 & 5-13

P/N 4277303B 5-15

HOST TO LH 750 WORKSTATION COMMUNICATIONS (HOST ToDo LIST)Delete Message

are required as separators. Note that a comma is required after TUBE ID even if it is not followed by a CASS/POS. This Test Field Data Format has additional flexibility in the Delete Function only.

NOTE: “TEST,TUBE ID,” represents an empty CASS/POS indicator and “TEST,CASS/POS” represents and empty TUBE ID indicator.

Additional format flexibility in the Delete Function only is as follows.

“,TUBE,ID,CASS/POS”shall represent an empty TEST indicator.

“,,CASS/POS” shall represent empty TEST and TUBE ID indictors.

“,TUBE ID,” shall represent empty TEST and CASS/POS indicators.

“TEST,,” shall represent empty TUBE ID and CASS/POS indicators.

“,,” shall represent empty TEST,TUBE ID, and CASS/POS indicators.

NOTE: The last entry has the same effect as an empty Test field.

In the Delete context, an Empty Indicator is interpreted to refer to all values of that indicator relative to the next highest indicator in the ToDo List. For example; If the TUBE ID indicator is not empty and the TEST indicator is empty, this is interpreted to mean “delete all TEST’s preassigned to this TUBE ID”. An empty Test field refers to all preassigned tests relative to a given Patient ID (this is also true for the Test Field Data Format”,,”).

It should be noted again, that if there is no Patient ID field, this is not the same as an empty Patient ID field. This is interpreted as referring to a preassignment with no Patient ID.

The following table illustrates the variables.

7.1 CRC ALGORITHMThe CRC algorithm used is a modified CCITT CRC16 algorithm and is the same as used in the STKS™ analyzer.

The polynomial for this algorithm is: X**16 + X**12 + X**5 + 1.

Note: D = current data byte that is input to the algorithm.

CRCLSB,CRCMSB = data byte. Least significant and most significant CRC accumulator bytes.

x>>n means x is shifted n bits to right or is the same as x divided by 2n.

x<<n means x is shifted n bits to left or is the same as x multiplied by 2n.

//------------------------------------------------------------------------------------------------------------------

at beginning,CRCLSB = 0FFH (octal 377) (decimal 255) CRCMSB = 0FFH (octal 377) (decimal 255)

then for each data byte in a block,X = D XOR CRCMSBX = X XOR ( X >> 4 )CRCMSB = CRCLSB XOR ( X >> 3 ) XOR ( X << 4 )CRCLSB = X XOR ( X << 5 )

and at end,CRCLSB = CRCLSB XOR 0FFHCRCMSB = CRCMSB XOR 0FFH

8GRAPHIC RECONSTRUCTION

8.1 RBC, WBC THRESHOLD, AND PLT HISTOGRAMSThe histograms display a simple line graph which is representative of the count of events occurring in each A/D channel (or voltage level). The histograms are transmitted as 512 ASCII bytes for RBC (256 bytes for PLT, 112 bytes for WBC and 512 bytes for WBC Full Histogram) representing a 256-byte for RBC (128-byte for PLT, 56 bytes for WBC and 256 bytes for WBC Full Histogram) Hex array. It takes two ASCII bytes to represent one Hex byte.

Each Hex byte represents a scaled count for each channel 0-255 (14-142 for PLT). The histograms can be constructed by plotting the count for each channel then drawing a line between plots.

To display (or print) the histogram you must plot the channel vs. count. The channel represents the X-axis while the count is the Y-axis (see Figure 8.1). There are 128 channels for the platelet histogram, 256 channels for RBC, 56 channels for WBC and 256 channels for WBC Full Histogram. The value range is 14-255 (0D-FF hex) for the platelet histogram and 0-255 (00-FF hex) for the WBC and RBC histograms.

Figure 8.1 Plotting RBC, WBC Threshold and PLT Histograms

8.2 LH 750 DATAPLOT FORMATThe 2-dimensional dataplots communicate a greater amount of information to the viewer about the events. The following sections describe the format of the dataplot data and provide a how-to example of displaying the dataplot data on a raster device such as a video display or printer.

DataplotsThe dataplots consist of two major components: dataplot data and rendering information. Taken together, these two components allow a receiving application to display the dataplots in the same fashion as the LH 750 Workstation.

The dataplot portion of the host transmission consists of a dataplot data header and one dataplot data block.

Dataplot Data HeaderThe dataplot data header tells the receiving application how large the dataplot transmission is and how many dataplot data blocks are contained in the transmission. A complete dataplot transmission, including the dataplot data header, is illustrated in Figure 8.2.

Figure 8.2 Dataplot Transmission

Dataplot Data Header ElementsThe dataplot data header contains two elements: the total length of the dataplot transmission and the number of dataplot data blocks in the transmission. The data are represented as one 16-bit integer which indicates the total size of the dataplot transmission and one 8-bit integer which indicates the total number of dataplot data blocks in the transmission (between 1 and 4). Only one block is supported currently, but up to four may be used in future software. See Figure 8.3 for details.

Figure 8.3 Dataplot Data Header

Dataplot Data BlockThe dataplot data block contains both the rendering information and the actual 2-dimensional dataplot data. Each dataplot data block is composed of four subsections: dataplot data block header, rendering information block, dataplot header and the dataplot data. Figure 8.4 illustrates the dataplot data block format.

Figure 8.5 Dataplot Data Block Header

Rendering Information BlockThe rendering information block contains information the receiver can use to reconstruct the dataplot as it was displayed by the LH 750 Workstation. The dataplots are color-coded to identify the population and dithered to code the density. The rendering information block contains color palettes and dither pattern bitmaps used by the LH 750 Workstation software when displaying or printing the dataplots. It is highly recommended that host software employ the same scheme when displaying the dataplots to maintain consistency of operator conclusions across platforms. See Figure 8.6. The structure of the rendering information block is as follows:

SC_TYPE_5DIFF (0x01) is 5 Part Differential Dataplot.

SC_TYPE_RETIC (0x02) is Reticulocyte Dataplot.

SC_TYPE_CD4 (0x04) is CD4‡ Subset Dataplot.

SC_TYPE_CD8 (0x05) is CD8‡ Subset Dataplot.

Dataplot Option code Dataplot Option Code is an 8-bit integer which contains option flags that pertain to the current dataplot. The following flags are currently defined and can be combined into Dataplot Option Code with a logical or when applicable:

SO_COMPRESSED (0x01) indicates that the dataplot has been compressed. This option is not supported currently, but may be available in future software.‡

SO_HAS_RENDER_INFO (0x02) indicates that a valid rendering information block follows.

Dataplot width (LSB) Dataplot width is a 16-bit integer which specifies the width of the dataplot.

Dataplot width (MSB)

Dataplot height (LSB) Dataplot height is a 16-bit integer which specifies the height of the dataplot.

Rendering Information Block HeaderThe rendering information block header contains fields which indicate the size and format of the bitmaps and the color palette. It is sent on the first transmission after a user log-on and a shutdown/restart occurs. As notification is not provided when a shutdown/restart is initiated, the rendering block transmission cannot be predicted in advance. Figure 8.7 is an illustration of the rendering information block header.
