GSIOC Control Appendix B

GSIOC Features

GSIOC stands for Gilson Serial Input Output

Channel. This communications channel links all of

the Gilson modules in a system together. The system

controller controls all of the modules in a system by

sending GSIOC commands to the slave modules, for

example pumps or detectors. Each device connected

to the GSIOC channel is distinguished by a GSIOC

identity number between 0 and 63. The GSIOC

identity number is set by switches inside each

module or by the module’s software. The controller

communicates with one slave device at a time. The

hardware and software requirements to control a

module from a computer using the GSIOC are as

follows:

• A PC running under Windows® 95, 98, NT, or

higher.

• A Gilson interface module, 506C.

• A Gilson HPLC system controller software package.

To get started you must:

• Install the Gilson HPLC system controller software

on the computer.

• Connect the computer to the Gilson interface

using the cable provided with the interface.

• Connect the output from the interface to the

Gilson module using a GSIOC cable.

• Start the Gilson HPLC system controller software.
