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.
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 cannot 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.
