4.7.3 Serial protocol
The serial interface link is set to 9600 Baud, 8 bits, 1 stop, no parity with no
handshaking. The commands are made up from printable ASCII characters. The
maximum message size that can be sent is 80 characters, that includes start and end
characters.
Note:
All alphabecal charact
ers must be sent in upper case format. Response can have lower
case characters.
Every complete command message sent will receive a response that follows:
▪ status code or
▪ data return
The pump accepts one message at a me. The pump will only accept a new message
when the response to the previous message has returned.
If the pump ignores the characters that are not framed in the start and stop characters.
Messages that does not have the stop character missing will be discarded with no
response when a new start character is received. If the pump receives an unrecognisable
message between the start and stop characters, it will reply an applicable error message.
Refer to Mul‐drop operaon on page 55 for more informaon about how to operate
the pumps in the mul‑drop mode.
