Chapter 4 Communication

Introduction

The DMC-3425 has one RS232 port and one Ethernet port. The RS-232 port is the data set. The Ethernet port is a 10Base-T link. The RS-232 is a standard serial link with communication baud rates up to 19.2kbaud.

For initial setup, Galil recommends starting with the RS-232 interface. The RS-232 provides a simplified interface that minimizes the potential problems for first time setup. Once the configuration parameters have been properly set and saved on the controller, the Ethernet communication should be established.
