ASTM-Protocol for option H

Definition
Term Definition

<ACK> Acknowledgment (ASCII Decimal 6)

[C1] The most significant character of Checksum
[C2] The least significant character of Checksum
[DATA] The data contents of the record
[ENQ] Inquire (ASCII Decimal 5)
[ETB] End of Transmission Block (ASCII Decimal 23). For use only when a single record is
too large to fit into one frame.
[ETX] End of Text (ASCII Decimal 3). Required at the end of each record.
[frame number] Single digit frame number “0” to “7”, starts with “1”.
<LF> Line Feed (ASCII Decimal 10).
<NAK> Negative Acknowledgment (ASCII Decimal 21).
<STX> Start of Frame (ASCII Decimal 2).
Communications All framing required for transmission of data. This framing includes: <STX>[frame
packet number][DATA] [<ETB> or <ETX>][C1][C2] <LF>
Field A specific location within a record for a piece of information, indicated by a field
delimiter and position.
Frame A complete communications packet.
LIS Laboratory Information System
BMx BM Mediff x=Number of Instrument
Message A collection of related information; a group of records that begins with a «Header»
record and ends with a «Terminator» record. A single record could theoretically
constitute a message, but within this context, a message always contains multiple
records
EOT End of Transmission (ASCII decimal 4)
<CR> Carriage Return (ASCII decimal 13)
Record In reference to the low level protocol, a record is the message data (shown as
[DATA]) as described within the communications packet. If the data is longer than
240 characters, then it must be split into two (or more) parts and sent in two (or
more) communications packets. The intermediate packet uses the <ETB> character,
and the ending packet uses the <ETX> character. No single communications
packet contains more than one record. In reference to the message layer, a record
can be one of the following codes: H (header), P (patient), O (order), R (result), L
(terminator), C (comment).
<BR /> Line break for multi-line comments

RS232 connection
Standard: 1 Startbit, 8 Databits, Even parity, 1 Stopbit, 9600 Baud
Description of Record
• Length of field can be less than maximum value but must not be more.
• Delimiter must be used even if field is free.
• Delimiters inside records are separate by «|» (ASCII $7C).
• Delimiters inside fields are separate by «^» (ASCII $5E)
Frame checksum
• According to ASTM E-1381 frame checksum (<STX>1...Data...<CR><ETX>xx<CR><LF>) is
• defined as modulo 256 of ASCII values sum between <STX> not included and <ETX>
• included characters: 1...Data...<CR><ETX>

Discussion with conflict between Instrument and Host

Number of transmission if negative answer (NACK): 6
Timeout if no response: 15s
Special timing: None
Description of other specific treatments: None
In case of ENQ\ENQ conflict analyzer waits 2s and tries emission again.
Mediff is master in case of conflict.

Example of Discussion with conflict between Instrument and Host

ASTM Data frame format

A sequential number located after the <STX> character is inserted into each Data frame.
Frame number is set to 1 when transfer phase is initialized and is incremented by 1 for each frame up
to 7 and then returns to 0.
Frame number is to permit receiver to distinguish between new and retransmitted frame, in case of
retransmitted frame (after a <NAK> response from Host), frame number is not incremented:
<STX>1...Data...<CR><ETX>xx<CR><LF>
