Using the Serial Port
Chapter Objectives The DL5 has a full duplexed RS-232 serial port which is used for:
•
communication with the offline programmer and for programming input
from a “dumb” ASCII terminal.
•
serial triggering of messages
The operation of the serial port is determined by the Serial Trigger/
Configure DIP switch on the back of the DL5 see page 2-2. The RS-232
serial port is a 9-pin male D-shell connector located at the rear of the DL5.
A drawing of the DL5’s connector is provided below:
The RS-232 port operates at baud rates of 300, 1200 and 9600 baud. The
rate is user selectable through the Special Functions Menu or the Offline
Programmer. The default baud rate of the DL5 is 9600 baud.
