INSTALLATION AND OPERATION INSTRUCTIONS
FUNCTIONAL DESCRIPTION
The
FBR-4V2A(M/S)-TX
and
FBR-4V2A(M/S)-RX
operate as a transmitter / receiver pair for the
transmission of four baseband NTSC or PAL video signals, with two channels of line-level, bi-
directional audio, over a single multimode or single-mode fiber.
The
FBR-4V2A(M/S)-TX
converts four video inputs, and two audio inputs, to an optical fiber output.
The
FBR-4V2A(M/S)-TX
also converts an optical fiber input, returning over the same fiber, into two
audio outputs.
The
FBR-4V2A(M/S)-RX
converts an optical fiber input into four video outputs, and two audio
outputs. The
FBR-4V2A(M/S)-RX
also converts two audio inputs into an optical fiber output, returning
over the same fiber.
These units are contained in compact and rugged steel housings with internal dc voltage regulation. The
detachable terminal blocks and LED indicators provide for easy installation and monitoring of video,
optical link, and dc power.
The units operate either surface mounted as modular, stand alone units, or within a rack mounted card
cage.
INSTALLATION
THE INSTALLATION OF THIS UNIT SHOULD BE MADE BY A QUALIFIED SERVICE
PERSON(S) AND MUST CONFORM TO ALL LOCAL CODES.
The general connectivity of the units is detailed in Figure 1.
Mount the unit to a secure surface using #8 (3mm) hardware in four places. See Figure 3 for a full size
mounting template. Be sure to allow sufficient room for the required minimum bend radius of the fiber
cable used.
POWER SOURCE
The unit requires a +12VDC power source for proper operation. The DC input is diode protected against
reverse polarity connection.
In the USA and in Canada, for standalone surface mounted installation, an Aventura Technologies FBR-
PSUS12DC1A is supplied with this unit. Contact Aventura Technologies for ordering power supply
units for use in countries other than the USA and Canada.
When installed in a rack mounted card cage, the power for the unit is supplied from the card cage’s
power supply.
POWER CONNECTION
Power is supplied to the unit via a two pin terminal connector. Follow the labeling on the unit for proper
connections of the +12 volt dc and ground leads.
VIDEO INPUT/OUTPUT CONNECTION
The video input and output connections are made via BNC connectors on the front of the units. The
video inputs and outputs are 75 ohms. For proper operation, the video outputs must be terminated with
