To loop a reference signal
1. Connect the
REF 1
LOOP BNC on the rear panel of the first frame to the
REF 1
IN BNC on the rear panel of
the next frame using a 75ohm coaxial cable.
2. Continue looping the REF connectors across the frames that you want reference to this signal.
3. Ensure that the last frame in the video referencing loop has a 75ohm termination connected to its REF 2 IN
BNC.
Troubleshooting
During normal operation, the GFC-8322 must never be removed from the OGX-FR frame. To ensure this, the metal
retaining latch located on the front of the GFC-8322 must be engaged (pushed down) to prevent accidental removal
of the GFC-8322 from its slot.
Verify that the GFC-8322 is properly seated in its slot and the retaining latch is engaged when troubleshooting any
of the following conditions:
• reference signals are unavailable to the cards installed in the OGX-FR frame
• loss of network connection or the network settings for the OGX-FR frame were reset to the default values
