Introduction

The DMC-14XX 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.

RS232 Port

The DMC-14XX 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.

Handshaking Modes
The RS232 port is configured for hardware handshaking. In this mode, the RTS and CTS lines are
used. The CTS line will go high whenever the DMC-14XX is not ready to receive additional
characters. The RTS line will inhibit the DMC-14XX from sending additional characters. Note: The
