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.

RS232 Port

The DMC-3425 has a single RS232 connection for sending and receiving commands from a PC or other terminal. The pin-outs for the RS232 connection are as follows.

RS232 - Port 1 DATATERM

1	CTS – output	6	CTS – output
2	Transmit Data - output	7	RTS – input
3	Receive Data - input	8	CTS – output
4	RTS – input	9	No connect (Can connect to +5V or sample clock)
5	Ground

RS-232 Configuration

Configure your PC for 8-bit data, one start-bit, one stop-bit, full duplex and no parity. The baud rate for the RS232 communication can be selected by selecting the proper jumper configuration on the DMC-3425 according to the table below.
