Models shown are for English on-screen menu model. The model
number and operating voltage are shown on the bottom of the unit.
These units are supplied with grounded power cords; grounding must
not be defeated.
4.2 Mounting
These switchers are half rack units and are supplied as
desk top units. For rack mounting, the LTC 9101/00
rack-mount kit is available.
4.3 Video Inputs and Looping Outputs
For each of the 4 or 8 channels, there are two BNC
connectors on the rear panel. One of these connectors
is to be used as a video input while the other connector
may be used as a looping output. It does not matter
which connector is used as the input and which is used
as the looping output. Each pair of BNCs provides an
automatic termination function that applies a 75 Ω load
to the incoming video signal when the cable is
connected to either jack. When "loop-through"
operation is desired, the second cable connection
automatically unterminates the input providing the
required high impedance for "loop-through" operation.
The jacks act as automatic switches. The looping video
outputs are provided to supply video to other video
equipment. When looping, the last piece of equipment
on the video line should be terminated.
4.4 Monitor Output
The monitor outputs are designed for a 75 Ω load.
Therefore, when looping the monitor output cable
through multiple monitors or their accessories, ensure
their terminations are set to Hi-Z. Only the last unit on
the line should have its termination set to 75 Ω.
LTC 5104 Series: A single monitor output permits
switched camera video through this connection.
LTC 5108 Series: These switchers may be used with
one or two monitors, depending on system
requirements. See Operating Mode section and Typical
Installation illustration.
