10 Connecting the VP-300T
You can use the VP-300T and, for example, the TP-120 to configure an XGA
Line-to-Twisted Pair Transmitter and Receiver system.
To connect the VP-300T with the TP-120, as the example in Figure 11
illustrates, do the following:
1. On the VP-300T 1:2 XGA DA/ CAT 5 Transmitter, connect the:
Computer graphics (XGA) source (for example, a
computer) to the INPUT 15-pin HD connector
OUTPUT 1 and OUTPUT 2 15-pin HD connectors to up
to
1
two acceptors (for example, to a display and to a
projector, respectively)
2. On the TP-120 XGA Line Receiver, connect the XGA OUT 15-pin HD
connector to the XGA acceptor (for example, a display).
3. Connect the LINE OUT RJ-45 connector on the VP-300T to the LINE IN
RJ-45 connector on the TP-120, via UTP cabling (with a range of more
than 300ft (more than 100m)), see section 11.1.
4. Connect the 12V DC power adapter to the power socket on the VP-300T,
and plug the adapter into the mains electricity socket. Similarly, connect the
other 12V DC power adapter to the power socket on the TP-120, and plug
that adapter into the mains electricity socket.
5. On the VP-300T, if required:
Set the ID Bit switch
6. On the TP-120, if required:
Adjust
2
the video output signal level and/or cable
compensation equalization level
Set the H SYNC and V SYNC switches
3
, on the underside
1 When both outputs are not required, connect only the output that is required and leave the other output unconnected
2 Use a screwdriver to carefully rotate the trimmer, adjusting the appropriate level
3 By default, both switches are set down (for normal V SYNC and H SYNC polarity)
