Protocol definition
Pump commands and responses are transferred in the form of
records. A record consists of a string of characters in a specific order.
Character Format - Version 0.67 and below
Each character transmitted over the link is an ASCII character using
• 1 start bit
• 7 data bits
• 1 odd parity bit
• 1 stop bit.
The seven data bits are transmitted in standard order, which is least
significant bit first, most significant bit last. Each character received
is examined for errors, including framing and parity errors.
Transmission is software selectable to 9600 (default), 4800, 2400,
1200, 600, 300 baud.
All characters in a command or response record are to consist of
printable ASCII characters only, in the range of 020 hex to 05F hex
and 061 hex to 07A hex. No control characters are allowed within a
record, but may be used between records as further defined below.
Any error found in any single character will constitute a corrupt
record and will be discarded, see Error processing , on page 12-7.
