Diagnostic Test 1: Serial Com Port 1 - Display Input Data

This test displays serial data as it is received by serial communications port 1. The

numeric display has limited alpha display capability, however numeric and some alpha

characters are legible. If all data being received is unintelligible, the baud rate is

probably incorrect. If nothing is displayed on the display, then check the following:
1.

RS232/Current loop switch on the main circuit board.

2.

Cabling between the communicating units.

3.

Make sure the sending unit is actually sending data.

Press the CLEAR key to exit diagnostic test 1.

Diagnostic Test 2: Serial Com Port 1 – Display Errors

This test displays the number of framing and parity errors that are detected in the input

data stream. The error count is set to zero when entering this test. New errors are

displayed as “PxxFxx” where Pxx is the number of parity errors and Fxx is the number of

framing errors. If the error count exceeds 99, the display will remain at 99.

Press the CLEAR key to exit Diagnostic test 2.
