Duplication and Expansion
Termination for Pre-wired Expansion Frames
The unused BNC connectors on the port expanders should be terminated
for best performance. However, it may be desirable to install an empty or
partially filled frame with associated cabling to simplify future expansion.
When such cabling connects to a Port expander that is carrying active sig-
nals, special termination hardware is required. Since the presence of pre-
wired cabling will not permit standard BNC terminators to be installed on
the expander, an
LD-33100 Loader board
must be installed in the associ-
ated frame in place of an input or output board to provide correct termina-
tion.
Grass Valley recommends that you terminate all unused outputs that may
be driven with an active signal. Properly shielded 75-ohm terminators or
spare infrastructure coax cables should be used. This step will ensure EMC
compliance. Spare output BNC panels that are not populated with output
boards and spare input BNCs do not need to be terminated.
