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.
