CALIBRATION PROCEDURE
Calibrating the Sender unit and Receiver unit
1. Make sure DIP switch 3 on both the Sender unit and the Receiver unit are in
the OFF position (see pages 9 and 11).
2. Connect one end of the fi ber cable to the Sender unit. Connect the other
end of the fi ber cable to the Receiver unit.
3. Connect the 5V DC Locking Power Supplies to the Sender unit and the
Receiver unit. Do not overtighten the locking connectors. Plug the power
cord into an available electrical outlet.
The LED indicators on both the Sender unit and Receiver unit will alternate from
red to green during the calibration process. The calibration process can take up
to 120 seconds to complete.
After the calibration process has fi nished, the LED indicators on both the Sender
unit and the Receiver unit will turn solid green. Set DIP switch 3 to the ON
position on both the Sender unit and the Receiver unit to lock the calibration set-
tings.
Troubleshooting
• If the Sender unit and Receiver unit did not complete the calibration process,
the indicator LEDs on both Sender unit and Receiver unit will be red. Check
the fi ber connections carefully and cycle the power on both the Sender unit
and the Receiver unit and repeat the calibration procedure.
• When the indicator LED at one unit is GREEN and the other is RED,
cycle power on the unit with the RED indicator. It is also recommended to
cycle power on both the Sender unit and the Receiver unit to perform a full
calibration.
• If the calibration procedure continues to fail, contact Gefen Technical
Support under the Asking For Assistance section at the beginning of this
manual.
IMPORTANT: Before beginning the calibration process, make sure that
the Sender unit and Receiver are not powered.
NOTE: If the fi ber optic cable is changed, follow steps 1 - 3 to repeat the
calibration procedure.
