INSTALLATION AND OPERATION MANUAL
FVT/FVR414
4-CHANNEL DIGITALLY ENCODED VIDEO
+ 4 BI-DIRECTIONAL DATA CHANNELS
The FVT/FVR414 is a four (4) channel video transmission system. It combines
four individual video signals into one high speed digital stream and transmits
this over one optical fiber.
The link also transmits four channels of bi-directional data over the same fiber.
Each data channel can be configured for an electrical interface of RS232,
RS422 or RS485 (2- or 4-Wire).
There is also a RELAY connector on both the Video Transmitter and Video Receiver
modules which indicates that the optical communication link is operating
properly. The Relay is CLOSED when the optical communication is good.
The Data Channels are labeled A, B, C and D. Each data channel is configured
for the electrical interface by means of the "DATA SELECT" switch on the front
panel. Figure 5 on Page 4 illustrates the switch settings to set the type of data
for each channel.
Figure 4 on Page 3 illustrates the data electrical connections from the RJ45 Data
connectors and also the connection cable and "breakout box" connections.
Figure 6 on Page 4 illustrates the specific data connections for RS232, 2-Wire
RS485 and RS422/4-Wire RS485. (This last data connection also applies to
Manchester & Bi-Phase data transmission.)
Figure 7 on Page 5 illustrates the electrical connections between the
"Customer Equipment" and the FVT414 and FVR414.
