Cheat sheet

driver.cheatSheet()

What it is

The Global Cache GC-100-12 network adapter has two RS-232 ports, three relays and six IR ports, each usable as an IR emitter output or a sensor input. It accepts one TCP client at a time on the Unified TCP API port 4998.

Specs

Type: Network adapter, 2 serial ports, 3 relays and 6 IR or sensor ports

Inputs: 2x DB9 RS-232, 3x relays, 6x 3.5 mm IR or sensor ports

Mounting: Desktop or rack shelf

Setup

First Use: With no DHCP server the unit takes 192.168.1.70. Serial port 1 crosses TCP 4999 and serial port 2 crosses TCP 5000. IR ports 1 to 6 are modules 4 and 5. A GC-100-18 reports itself as a GC-100-12 and uses this model. The GC-100 accepts one TCP client on port 4998, and one per serial port. What happens to a second client is not documented.

Support

Tech Support Phone: 541-899-4800

Power Cycle: Remove power for ten seconds. Relay states return to open after a reset or power cycle.
