GSIOC Control Appendix B
GSIOC Commands
Identification of the master pump (pump A) is not
critical. However, if a Model 305 is used with a
computer-based Gilson system, its ID number must
be cleaned in the Setup menu of the software
package (Model 704, 712, 714 or 715).
Command Examples
Example 1: GSIOC Command - Zeroing the
Manometric Module
In order to zero the Manometric Module when
controlling the 305 from a computer-based system
controller, stop all pumps, or pause without flow.
This ensures no actual pressure inside the
Manometric Module. The following GSIOC
commands must be entered:
Send the zeroing K buffered command string. From
the ready-to-run menu, this command string is
made up of: Kdbbce.
This mimics the following key entry sequence:
<Menu>, <I/O>, <Prev>, <Zero>, and <Quit>.
This command can be sent before the run by using
the “GSIOC Control” option of the “Manual”
menu. It can also be added to the method as a
GSIOC event (“Edit” menu, “GSIOC Events” or
“Gilson Instruments” option).
Example 2:
To write “HELLO” on the
upper line of the display
and “My name is Model
305” on the lower line.
Example 3:
To remote read the
display.
The use of the lowercase
w immediate command
allows you to read
messages displayed
before the use of the W
buffered write command.
