RUNNING THE FIBER OWL 4 SERIAL PORT DIAGNOSTIC – PAGE 2 OF 2

OPERATION/MAINTENANCE

TEST 1 - DATA PORT TEST

At this time, do NOT attach the download cable to the DATA port. Press

to run the

DATA PORT TEST.

The result of the DATA PORT TEST should be “FAILED”. This means that the Fiber OWL 4 data
port is functioning properly.

If the result of the DATA PORT TEST is “PASSED”, then there may be a problem with the Fiber OWL
4 data port. Do NOT continue with the rest of the diagnostic tests, and contact OWL technical
support.

TEST 2 - RS-232 DOWNLOAD CABLE TEST

Now, connect the RS-232 download cable to the serial port on the top of the Fiber OWL 4.

Press

(RETEST), then

to run the RS-232 download cable test. At this time, do NOT short pins 2 and 3 together

on the DB-9 connector.

The result of the RS-232 DOWNLOAD CABLE TEST should also be “FAILED”. This means that
there are no internal shorts in the cable.

If the result of the DOWNLOAD CABLE TEST is “PASSED”, then there may be a problem with the
download cable and it should be replaced.

TEST 3 - SERIAL PORT DIAGNOSTIC TEST

Short pins 2 and 3 on the download cable with a short piece of wire

as shown in the picture at right. A paper clip works well for this connection.

Press

(RETEST), then

to run

the SERIAL PORT

DIAGNOSTIC TEST.

The result of the SERIAL PORT DIAGNOSTIC TEST should be “PASSED”.
This confirms that the DATA port on the Fiber OWL 4 and download cable are
working together properly.

If the result of this test is “FAILED”, re-seat the loopback wire and download
cable to make sure the connections are firm and re-test.

If you have any questions about this diagnostic procedure, please contact OWL at 262-473-0643.
