1. Zellweger CM4 Description

The Zellweger CM4 driver allows the FieldServer to transfer data to and from devices over either RS232 or RS485 using Zellweger CM4 protocol.

The information that follows describes how to expand upon the factory defaults provided in the configuration files included with the FieldServer.

1.1 Hardware/Software

Supplied by FieldServer Technologies.
