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 the 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. Contact a 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 48-cm (19-in.)
rack.
