1. The POWER LED illuminates when AC power is
applied to the unit.
2. LTC 4744/00 units: Although this module provides
both front and rear mounted BNC input connectors
for installation convenience, each input channel is
capable of accepting only a single video signal.
NOTE: Avoid simultaneously connecting video signals
to both the front BNC and rear BNC of the same
channel. Also, since each video channel is factory
terminated to 75 ohm, unused BNCs should not be
used for loop-through video connections.
