Serial Port
This diagnostic screen allows you to test the control serial ports. To perform the test,
install the appropriate jumper or jumpers. If the serial port you are testing is configured
for RS-232, jump pin 2 to pin 3. If you are testing a serial port that is configured for RS-
422, jump pin 2 to pin 3 and pin 4 to pin 7. Select the appropriate serial port to test and
press the Test Port soft key to initiate the test.
If the serial port is functioning properly, the text in the Send window will appear in the
Received window. If the serial port is not functioning properly, a Communications Time
Out message will appear below the Received window. If the serial port test fails, the
control may be defective and the factory should be consulted for further instructions.
Below is a serial port test screen with a successful test.
