1INTRODUCTION

1.1 PURPOSEThis document is the specification for communication between the LH Series Workstationand a host computer. The functionality will remain backward compatible. This document isintended for use by software engineers needing to either maintain or modify the operation of

the LH Series Workstation Host Communications.

This document describes the transfer of data from the LH Series Workstation to an LIS/HIScomputer in the following formats:

r STKS 1G.1 + Retics

r LH 750 Workstation: host communication protocol which supports transmission ofCBC, DIFF and Reticulocytes parameters for samples and control runs as well ascollated 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 MAXMinterfaces. Due to the LH Series Workstations new features and enhancements, STKS and

MAXM instrument formats are not completely supported (see details in following sections).

INTRODUCTIONPURPOSE


15/132PN 4277303EC 2-1

2HARDWARE INTERFACE

The system is equipped with a Host connector on the rear of the LH SeriesWorkstation thatlets the system interface with a host computer via a Standard EIA-type 25-pin connector anduses EIA Standard RS-232-C signals. The LH 500 is equipped with a 9 pin to 25 pin adapterallowing the system to interface with a host computer. The LH 500 and LH 700 Series tower

computers must use the standard EIA-type 25 pin connector. The LH 700 Series Small FormFactor (SFF) must use a standard EIA-type 9-pin connector. This is a Data TerminalEquipment (DTE) configuration.

The LH SeriesWorkstation/Host communications uses only the following signals:

Table 2.1 Signal and Flow Direction for the DB 25-pin connector

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

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

HARDWARE INTERFACEHARDWARE HANDSHAKE

The LH Series Workstation is the DTE, by RS-232 Standards, which explains the RTS/DTRpin-outs. Whether the HOST is a DTE or DCE will determine its use of CTC/DSTorRTS/DTR. A DTE HOST requires the use of a NULL MODEM cable.

Pin 8 CTS must be active for LH Series workstation to send any transmission. It is necessaryto connect pin 7 to pin 8. The 9-pin configuration cable uses the signals listed in Table 2.2,Signal and Flow Direction for the DB 9-pin connector. .

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

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

3COMMUNICATION PARAMETERS

3.1 COMMUNICATION PARAMETERSThe LH SeriesWorkstation allows the user to configure the following communicationparameters on the Host Computer Definition screen. These parameters includecommunication 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 toactual information. Presentation protocol describes the actual information and its format.

Low Level Protocol

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

High Level Protocol

The High Level Communication Protocols currently supported are theSTKS 1G.1 + Retics and LH 750 Workstation. The High Level Communication Protocolis selected using the compatibility field.

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

COMMUNICATION PARAMETERSLIS COM PORT CONFIGURATION

3.3 LIS COM PORT CONFIGURATIONIMPORTANT The current LIS cable that connects to the Equinox Host 1 port is different from the LIS cablethat connects to the COM Port 1 (pin layout is different). UI COM Port selection and physical communicationcable connection are based upon workstation type.

For the LH 700 Series workstation, the COM Port can be configured to COM 1 or COM 6,depending on the workstation:

r For the LH 700 Series tower-type computers, the default COM Port 6 must be usedwitha DB 25-pin connector. See Figure 8.12, Space for tower-type computersand Figure 3.1,Rear of instrument with DB 25-pin connector for tower-type computers.

r For the LH 700 Series Small Form Factor computers (SFF), COM Port 1 must be usedwith a DB 9-pin connector. See Figure 8.13, Space for Small Form Factor (SFF)-typecomputersand Figure 3.2, Rear of instrument with DB 9-pin connector for SFF-typecomputers.

Refer to the following Table 3.2, COM Port Mappingfor the correlation between ports and

hardware configuration.

COMMUNICATION PARAMETERSTIME-OUT

Figure 3.2 Rear of instrument with DB 9-pin connector for SFF-type computers

Note: The 9-pin serial connector on the computer base, designated as COM 1, is locatedbeside the video display connector.

3.4 TIME-OUTThe time-out value determines the amount of time the LH SeriesWorkstation waits for aresponse from the host before retrying to send data to the host. The LH SeriesWorkstationcontinues 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.

Timeout settings at the host should be configured to optimize the flow of communications.While the LH Series Workstation responds to most transmissions very quickly, allowing alonger timeout for worst-case scenarios under heavy load conditions can help keep thecommunications synchronized, and therefore maximize overall communication throughput.We recommend allowing at least 90 seconds at the end of a host order transmission whilewaiting for the DLE response, and at least 30 seconds for all other responses.

3.5 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 9600Baud for graphic transmissions.

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

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


20/132PN 4277303EC3-4

COMMUNICATION PARAMETERSSTOP BITS

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

3.9 HANDSHAKEThis option determines whether or not the LH SeriesWorkstation looks for a handshake fromthe host computer. See Heading 4.1, Data-Link, for additional information.

3.10 BLOCK SIZEThe LH SeriesWorkstation/Host Communications support block sizes of 128 and 256 bytes.The default value is 256 bytes.

3.11 GRAPHICSThe LH SeriesWorkstation allows DIFF and Retic graphic transmission if the compatibilityformat selected is the LH SeriesWorkstation format.

Table 3.3lists the graphic items that can be enabled or disabled for the corresponding testbased on the current compatibility format and report profile selected.

3.12 COMPATIBILITYThis option determines which transmission format is used by the LH SeriesWorkstation tosend results to an LIS/HIS computer. The Host High Level Communication Protocolssupported are: STKS 1G.1 + Retics and LH 750 Workstation.

3.13 SPOOLERTransmissions to the Host are spooled before sending. When a transmission is sent to theHost, it will be kept on the Spooler and resent until the Host acknowledges that thetransmission 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 Hostcomes online or the Host Spooler is cleared.

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

COMMUNICATION PARAMETERSREPLACE NULL BY SP

3.15 REPLACE NULL BY SPThis is no longer an option because NULL characters are not included in the transmissionbuffer.

3.16 DISABLING HOST COMMUNICATIONSSelect the Disable button in the LIS folder on the System Run Configuration screen to disableall auto transmissions from the LH SeriesWorkstation to the Host. This will not affect manualtransmissions or transmissions from the Host to the LH SeriesWorkstation.

3.17 ENABLE VALIDATION CODESThis checkbox enables the codes used to identify the validation status of individual testrequests on a sample as detailed in Conditional Flags Group Fieldsunder AutoValidation inChapter 4. If Enable Validation Codes in System Setup - [Communications] is checked(default), the individual test group validation status will be transmitted. Applied only toLH 750 format.

4LH SERIES WORKSTATION TO HOST COMMUNICATIONS

4.1 DATA-LINKA sample transmission to the Host consists of one or more framed data blocks. See Data BlockStructure below. All transmitted data bytes are ASCII characters. All numeric values are ASCIIrepresentations 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 transmissionare the number of blocks to be sent, in ASCII, followed by transmission of data blocks (seeformat below).

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

The LH Series Workstation supports full software handshake and no software handshakeprotocols.

Full Software Handshake

The LH Series Workstation sends the following control characters plus data and expects theindicated host response:

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

Software Handshake Action

If the host NAKs a data block, the block is retransmitted. It is up to the host to determine howmany times it retries receiving a NAKed block before aborting. Typically, the Host will NAK adatablock if the current block number is incorrect(e.g. out of sequence), the Hosts calculatedCRC does not match the transmitted blocks CRC or block framing is not recognized ascorrect.

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

LH Series Workstation(SENDER) HOST (RECEIVER)

SYN (ready)------>

for each block


24/132PN 4277303EC4-2

LH SERIES WORKSTATION TO HOST COMMUNICATIONSDATA-LINK

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

The LH Series 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 blockof the transmission and discard it locally.

No Handshake

If Handshake option is disabled, the protocol ignores all hardware and software hosthandshake responses. In addition, in the No Handshake mode, the LH SeriesWorkstationdoes not send a SYN prior to transmitting the data. CTS is always used to indicate that a Hostis MS and turned on.

NOTE:The option to turn off handshaking is suppoprted for backward compatibility. This isnot recommended as it has been shown to cause problems at slower baud rates that mayresult in corrupted or last data (during high volume times).

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 ASCIIstarting with the number 1(MS byte = 30H, LS byte = 31H, to give 01) for the first block. Theblock number of the last block must equal the Block Count sent at the beginning of thetransmission.

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

25/132PN 4277303EC 4-3

LH SERIES WORKSTATION TO HOST COMMUNICATIONSDATA-LINK

The CRC for the blocks data is calculated by the workstation and sent as the last four bytes ofthe 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 isonly calculated on the data bytes.

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

Message Structure

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

Preamble

The preamble marks the beginning of a message.

Group

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

Each Group contains a DC1 (11H) character, marking the beginning of the section, a twocharacter 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 Count

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

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

Fields

Each Group is made up of variable length fields which may or may not be padded withSP (20H) characters. A field may have a variable length tag preceding the data separated withone SP (20H) character. The data portion of a field will only contain ASCII characters in therange of 20H to 7EH inclusive. Chapter 6 tabulates the valid ASCII characters. Fields areseparated 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 Groupmay appear in any order or may be omitted. The CR/LF should be used to find a field and theTag 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 thecurrent implementation of the STKS 1G.1 + Retics format. Future revisions may includeadditional groups. Any future additions will not disrupt the numbering of the groups aspresently defined.

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)

Message Structure

The Presentation deals with the high level format of the message. The data bytes of thetransmission 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 thisparticular 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. Thetransmission test will never be transmitted out of order.

The Transmission Tests are up to 32 characters long. Table 4.18lists the availableTransmission 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 testidentification 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 oftests contained within the transmission. Valid test type count can be from 0-255. The test typecount 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 containedwithin 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.

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 theGroup. 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 SP (20H) character. Please note that all field transmissions will include a SPbetween 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 7EHinclusive. Heading 6.2, VALID HOST COMMUNICATIONS ASCII CODESidentifies the validASCII 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 Groupmay appear in any order or may be omitted. The CR/LF should be used to find fields and theTag used to identify it.
