GSIOC Commands
GSIOC Control
The Gilson Serial Input/Output Channel (GSIOC) is a communications interface that
enhances the power of your Gilson equipment.
The GSIOC incorporates a standard EIA RS-485 interface and allows 32 slave devices to
be controlled from a single master controller in a multi-drop configuration. The controller
is usually a computer.
Each slave device is identified by a unique number which must be known to the
device and to the controller. The unit ID of the VALVEMATE is 35. But you can set its
unit ID to another number. Refer to Checking the VALVEMATE’s Configuration in
Section 2 for information on how to change the VALVEMATE’s unit ID and the baud
rate setting.
To control one or more VALVEMATEs via the GSIOC interface, you need the following.
• Personal computer
• RS-232 or GSIOC connection to the VALVEMATE
• Gilson control software or 706 Device Driver Software and your program
From the computer, you can do the following:
• Specify the VALVEMATE as the instrument that you want to control.
• Issue commands that set operating parameters, control operation, or request
information from the VALVEMATE—see command list on the next page.
