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
display. The data will not transmit if the BUSY signal (TB4 pin 14) is active (TTL high).
Check the cable connections and the sending device.
