INSTALLATION AND OPERATION MANUAL
FVT/FVR280D8
28-CHANNEL DIGITALLY ENCODED VIDEO
+ 8 CHANNELS OF BI-DIRECTIONAL DATA
The FVT/FVR280D8 is a twenty-eight (28) channel ten (10) bit digitally encoded
video transmission system. It combines twenty-eight individual video signals into
one high speed digital stream along with eight channels of bi-directional data and
transmits this over one optical fiber. The FVT/FVR280D8 consists of a twenty-
eight channel video transmitter (FVT280D8) and a twenty-eight channel video
receiver (FVR280D8). The first module (A) also transmits and receives eight
bi-directional data channels: RS232, RS422 and RS485 (2W & 4W).
Both the transmitter and receiver are made up from six modules:
1 × 8 Channel Video Module with 8 bi-directional data channels (Module “A”)
2 × 8 Channel Video Modules labeled “B”, “C” and “D”
1 × 4 Channel Video Modules labeled “B”, “C” and “D”
1 × Passive Optical Wavelength Division Multiplexor (WDM)
1 × Chassis with integral power supply
The outputs of the four (4) Video Modules are combined at the transmitter into a
single optical signal by means of the WDM and separated out at the receiver with an
identical WDM. The video channels are referred to as A1, A2, etc., and B1, B2, etc.
A video input to the A3 transmitter BNC connector will be received out of the A3 BNC
on the corresponding video module.
The FVT280D8 and the FVR280D8 come completely assembled and tested from
the factory. There are no optical or electrical adjustments required or permitted.
However, the DATA CHANNELS must be configured for the specific type of data;
i.e. RS232, RS422 or RS485 2W or 4W. See Figure 5 on Page 5 for specific switch
settings. See Figures 1 – 7 for complete installation instructions.
