GSIOC Commands
GSIOC Commands
The GSIOC commands can be used to control
Gilson modules directly from a computer or from a
Gilson HPLC system controller software package.
The use of the GSIOC commands is completely
detailed in the 305 technical manual.
305 Commands
Specific 305 GSIOC commands
consider the pump as a set of periph-
eral devices which can be either
processed by the internal software,
or by the GSIOC bus. There are two
device types: input devices and
output devices.
- 305 input devices are: the Keypad,
Contact Inputs, and the Pressure
Input.
- 305 output devices are: the Upper
Line of Display, the Lower Line of
Display, and Contact Outputs.
All commands are detailed below
with their type, mode and function.
Immediate commands have their
response format described. Buffered
command parameters are
documented. Comments are added
where necessary.
Immediate % Request Module Identification
Response format: “305 Va.bc” where
Va.bc is the software version.
Immediate $ Master Reset
Response format: $ is echoed.
Buffered I Write Contact Inputs
Syntax: Iabcd where
a is the START/STOP input,
b the PAUSE input,
c the IN#1 input, and
d the IN#2 input.
Parameters:
“C” for closed “D” for open, “X” for state unchanged,
“-” for reconnected to internal software
Command example: “I-XCD” to reconnect START/STOP to the internal
software, leave PAUSE as it is, close IN#1, and open IN#2.
