Description of syntax expansion
10.2.2
RS-232 Protocol: Basic Mode
Command syntax (to pump):
<basic command protocol> => <command data> <CR>
Response syntax (from pump):
<basic response protocol> => <STX> <response data> <ETX>
In the “Basic” communications mode, a master-slave protocol is used, whereby the pump will only transmit in
response to a received command.
When the pump receives the <basic command protocol>, <command data> will automatically be stripped of
all space and control characters, and all text will be converted to upper case. This simplifies communications
with the pump when commands are being manually typed in from a generic terminal emulator.
To return the pump to Basic mode when in the Safe mode, send the following packet to the pump:
(0x2) ( 0x8) SAF0 (0x55) (0x43) (0x3)
10.2.3
RS-232 Protocol: Safe Mode
Command syntax (to pump):
<safe command protocol> => <STX> <length> <command data> <CRC 16> <ETX>
Response syntax (from pump):
<safe response protocol> => <STX> <length> <response data> <CRC 16> <ETX>
Safe mode uses a more structured protocol including detection of corrupted communications, communications
time outs, and auto-alarm responses. Safe mode is enabled using the ‘SAF’ command whose parameter setting
is stored in the non-volatile memory.
