Cheat sheet

driver.cheatSheet()

What it is

The Global Cache Global Connect serial module puts one RS-232 port on the network. Serial data crosses TCP port 4999 unchanged, and the port's settings are read and set on port 4998.

Specs

Type: Global Connect RS-232 module

Inputs: 1x RS-232

Mounting: Global Connect chassis

Setup

First Use: With no DHCP server after two minutes the module takes 192.168.1.70 plus its chassis position. Serial data crosses TCP 4999; plan for 4 clients there, since documents give 4 or 8. Each module is its own device with its own IP address. Up to 8 clients on port 4998; opening one more closes the oldest. The factory baud rate is 19200 in the API table and 115200 in every example; read it with GET SERIAL CONFIG.

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.
