Introduction 1 The Gilson 508 Interface Module connects your computer to many instruments made by Gilson. It permits bi-directional communication by interconverting the RS-232 signal levels used by computers and the RS-422/485 signal levels required by the Gilson Serial Input/Output Channel (GSIOC).

Operation 3 The 508 Interface Module provides RS-232-to-GSIOC interface from the computer. Gilson control software packages let you issue GSIOC commands that communicate with any GSIOC device connected to the interface module.
3 Status Lights Operation Status Lights The status lights on the 508 Interface Module are useful for verifying operation. If the Power light is off, power is not being sent to the interface module. If the RS-232 light is flashing, the 508 Interface Module is responding to the RS-232 input. If the GSIOC light is flashing, the 508 Interface Module is receiving a response from a GSIOC device.
Maintenance 4 The 508 Interface Module should not require maintenance. The best precautions for continued operation are to avoid spilling liquids on the connectors and to avoid mechanical strain on the wire connections.
