Diagnostic Test 4: Serial Com Port 2 - Display Input Data
Diagnostic Test 14: Serial Com Port 3 - Display Input Data
This test displays serial data as it is received by serial communications port 1, 2, or 3.
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 (com. port 1).
RS232/RS485 jumper on the main circuit board (com port 2).
2.
Cabling between the communicating units.
3.
Make sure the sending unit is actually sending data.
Press the CLEAR key to exit the diagnostic test.
