4.4 LTC 5231/90 Video Loss Outputs
The LTC 5231/90 Distribution Amplifier has a video
loss output, which is a set of relay contacts that
automatically close when there is a loss of video signal.
The VIDEO LOSS OUTPUT connections are made
through the 9-pin connector on the back panel of the
unit. The contact rating is 1 ampere at a maximum of
40 volts AC or DC. A 9-pin cable is supplied with the
unit that mates to the connector, for video loss output
connections. See Figure 1 for pin connections.
4.5 LTC 5234/90 Video Inputs
and Outputs
In a simple application, the output from a single video
source such as a camera, switcher, or DVR/VCR is
connected to one of four signal INPUT connectors on
the back panel of the distribution amplifier. The four
inputs have fixed 75Ω terminations.
Each signal INPUT has three (3) OUTPUT
connectors, allowing up to 12 video output connections
at a time. Devices connected to the outputs must be set
for 75Ω termination. If multiple pieces of equipment
are being looped from a single video OUTPUT, the
last piece of equipment must have a 75Ω termination.
See TYPICAL INSTALLATION.
4.6 LTC 5234/90 Video Loss Outputs
The LTC 5234/90 Video Distribution Amplifier has
four (4) video loss outputs, which are sets of relay
contacts that automatically close when there is a loss of
video signal. The video loss output connections are
made through the 9-pin connector on the back panel of
the unit. The contact rating is 1 ampere at a maximum
of 40 volts AC or DC. A 9-pin cable is supplied with the
unit that mates to the connector, for video loss output
connections. See Figure 2 for pin connections.
5.0 OPERATION
These units require no operational adjustments. The
power ON indicator illuminates when power is applied
to the unit, and the VIDEO indicators illuminate when
video is supplied to the inputs.
