Diagnostic Test 3: Serial Com Port 1 - Transmit Data
This test transmits data out of serial communications port 1. The display prompts: "OUT 0".
Press the enter key to send data. Serial Port 1 transmits "1234567890ABCDEF" and prompts
"OUT 1" to indicate that 1 transmission has occurred. Press the enter key again or press the
clear key to exit diagnostic test 3.
NOTE: If the error message "Er CtS" appears, the data can not be transmitted because the
handshake signal, clear-to-send (TB1 pin 7), is low or not connected. If clear-to-send is not used,
jumper it to data-terminal-ready (TB1 pin 4)
Diagnostic Test 4: Serial Com Port 2 - Display Input Data
This test displays serial data as it is received by serial communications port 2. 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/RS485 jumper 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 4.
Diagnostic Test 5: Serial Com Port 2 – 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 5.
Diagnostic Test 6: Serial Com Port 2 - Transmit Data
This test transmits data out of serial communications port 2. The display prompts: "OUT 0".
Press the ENTER key to send data. Serial Port 2 transmits "1234567890ABCDEF" and
prompts "OUT 1" to indicate that 1 transmission has occurred. Press the ENTER key again or
press the clear key to exit diagnostic test 6.
