Cheat sheet

driver.cheatSheet()

What it is

A Global Cache Flex on the RS-485 serial cable puts one two-wire or four-wire RS-485 port on the network. Serial data crosses TCP port 4999 unchanged.

Specs

Type: RS-485 on a Flex Link cable (FLC-SL-485)

Inputs: 1x RS-485 terminal block

Mounting: Desktop or surface

Setup

First Use: Set the cable mode with SET MODE SERIAL, then SET SERIAL CONFIG with DUPLEX HALF or FULL. Serial data crosses TCP 4999. Works on a Flex IP, Flex IP PoE or Flex WiFi base unit. The cable mode, not the base unit, decides which commands answer. With no DHCP server a Flex IP takes 192.168.1.70. Up to 8 clients on port 4998.

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.
