3 Overview
The VP-300THD is a high-performance distribution amplifier for computer
graphics video signals1 with resolutions ranging from VGA through UXGA
and higher as well as HDTV. It takes one input, provides correct buffering
and isolation, and distributes the signal to two computer graphics video or
HDTV outputs and one twisted pair output.
The VP-300THD features:
•HDTV compatibility
•H & V sync polarity switches for improved HDTV compatibility with
the CAT 5 outputs
•ID bit control
•A resolution of up to WUXGA and 1080p
•A transmission range of more than 300 feet (more than 100 meters)
•The Power Connect feature (see section 3.1)
•12V DC power
To achieve the best performance:
•Use only good quality connection cables2 to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables).
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer
VP-300THD away from moisture, excessive sunlight and dust

3.1 About the Power Connect Feature
The Power Connect feature applies as long as the cable can carry power.
This feature is available when using STP cable and the distance does not
exceed 50m on standard CAT 5 cable. For longer distances, heavy gauge
cable should be used1. For units which are connected via RJ-45 connectors,
make sure that the shield of the STP cable is connected to the metal casing
of the connectors on both ends of the cable. For units which are connected
via terminal block connectors, the shield of the STP cable must be
connected to a ground terminal on the units at both ends (use the ground
terminal of the power supply connection if necessary).
For a CAT 5 cable exceeding a distance of 50m, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
We recommend that you use Shielded Twisted Pair (STP) cable. There are
different levels of STP cable available, and we advise you to use the best
quality STP cable that you can afford. Our non-skew-free cable, Kramer
BC-STP is intended for analog signals where skewing is not an issue. For
cases where there is skewing, our UTP skew-free cable, Kramer BC-XTP,
may be used. Bear in mind, though, that we advise using STP cables where
possible, since the compliance to electromagnetic interference was tested
using those cables.
Although Unshielded Twisted Pair (UTP) cable might be preferred for long
range applications, the UTP cable should be installed far away from electric
cables, motors and so on, which are prone to create electrical interference.
However, since the use of UTP cable might cause inconformity to
electromagnetic standards, Kramer does not commit to meeting the standard
with UTP cable.
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

5 Connecting the VP-300THD
You can use the VP-300THD and, for example, the TP-120 to configure an
XGA/HD DA/CAT 5 Transmitter and Receiver system.
To connect the VP-300THD with the TP-120, as the example in Figure 3
illustrates, do the following:
1. On the VP-300THD 1:2 XGA/HD DA/CAT 5 Transmitter, connect the:
Computer graphics (XGA / HD) source (for example, a computer)
to the INPUT 15-pin HD connector
OUTPUT 1 and OUTPUT 2 15-pin HD connectors to up to4 two
acceptors (for example, to a display and to a projector,
respectively)
1 Downgoing syncs
2 By default, both switches are set to the left
3 The default. Enabling the notebook or laptop to output a VGA signal to an external VGA monitor
4 When both outputs are not required, connect only the output that is required and leave the other output unconnected

2. On the TP-120 XGA Line Receiver, connect the XGA OUT 15-pin HD
connector to the XGA / HD acceptor (for example, a display).
3. Connect the LINE OUT RJ-45 connector on the VP-300THD to the LINE
IN RJ-45 connector on the TP-120, via UTP cabling (with a range of more
than 300ft (more than 100 meters)), see section 3.2.
4. Connect the 12V DC power adapter to the power socket on the
VP-300THD, 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-300THD, if required:
Set the ID BIT switch to ON
Set the VS and HS switches1 on the underside
6. On the TP-120, if required:
Adjust2 the video output signal level and/or cable compensation
equalization level
Set the H SYNC and V SYNC switches3, on the underside
Figure 3: Connecting the VP-300THD
1 By default, both switches are set to the left (to NORMAL) to retain the VS and HS polarity
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)
