Diagnostic Tests

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.

Diagnostic Test 7: Test parallel output

This test transmits data out the parallel TTL I/O port. The display prompts: “dAtA”.

Use the numeric keyboard to enter data. Press the ENTER key to transmit the data. If

the data is successfully sent, “ 1= xxx” is displayed, where xxx is the first 3 characters of

the data sent and 1= is the number of times that the data has been sent. Press the ENTER

key to send the data again. Press the CLEAR key for the “dAtA” prompt. Enter new

data to transmit or press the CLEAR key to exit diagnostic test 3.
If the data is not successfully sent, the display will remain blank. If data is not sent

within 15 seconds, “Err 13” is displayed. Press the CLEAR key to exit from the error
