3.0 DESCRIPTION
The LTC 5231/90 and LTC 5234/90 are video
distribution amplifiers that provide multiple video
outputs identical to the video input signal. Their ample
bandwidth easily supports today's high-resolution video
signals. A video-loss-detection feature is available for
interfacing to external monitoring equipment.
The LTC 5231/90 and LTC 5234/90 also support
Bilinx technology, allowing bidirectional
communication through the video cable to access and
control Bilinx-enabled devices such as AutoDome and
Dinion cameras. A maximum of two (2) different types
of Bilinx controller models can communicate to a
common Bilinx-capable camera. Check with Bosch
Security Systems Sales Representative regarding future
product capabilities.
The LTC 5231/90 is a single-channel video distribution
amplifier with four (4) video outputs for distribution to
other video devices. A front panel LED indicates the
presence of video.
The LTC 5234/90 is a 4-channel video distribution
amplifier. It has four (4) independent distribution
amplifiers, each with one input and three outputs.
Front panel LEDs for each distribution amplifier
channel indicates the presence of video.
These are indoor products and supplied as desktop
units. Rack-mount kits are available from Bosch
Security Systems for mounting in a standard EIA
19-inch rack.
4.0 INSTALLATION
4.1 Power
LTC 5231/90 and LTC 5234/90 models operate at
120/230 VAC, 50/60 Hz power. The model number is
shown on the label located on the bottom of the unit.
These units are supplied with grounded power cords;
grounding must not be defeated.
4.2 Mounting
These amplifiers are supplied as desktop units. For rack
mounting, the LTC 9101/00 Rack-mount Kit is
available.
4.3 LTC 5231/90 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 the signal INPUT connector on the back
panel of the distribution amplifier. The video input has
a fixed 75Ω termination.
The LTC 5231/90 has four (4) OUTPUT connectors,
allowing up to four 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.
