1 Introduction
Welcome to Kramer Electronics (since 1981): a world of unique, creative and
affordable solutions to the infinite range of problems that confront the video,
audio and presentation professional on a daily basis. In recent years, we have
redesigned and upgraded most of our line, making the best even better! Our
500-plus different models now appear in 8 Groups1, which are clearly defined
by function. Congratulations on purchasing your Kramer VP-300THD 1:2
XGA/HD DA/CAT5 Transmitter, which is ideal for:
Presentation and multimedia applications
Long range graphics distribution for schools, hospitals, security, and stores
The package includes the VP-300THD 1:2 XGA/HD DA/CAT5 Transmitter,
power adapter (12V DC Input), and this user manual2.
2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Use Kramer high performance high resolution cables3
3 Overview
This section describes:
The power connect feature, see section 3.1
Using shielded twisted pair (STP) / unshielded twisted pair (UTP), see
section 3.2
A summary of the VP-300THD, see section 3.3
Recommendations for achieving the best performance, see section 3.4
3.1 About the Power Connect Feature
The Power Connect feature lets you power a transmitter / receiver system by
connecting just one power adapter—to either the transmitter or the receiver.
The other unit is fed via the cable connecting between the transmitter/receiver.

Overview
2
The Power Connect feature applies as long as the cable can carry power. The
distance does not exceed 50 meters on standard CAT5 cable, for longer
distances, heavy gauge cable should be used1.
For a CAT5 cable exceeding a distance of 50 meters, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application. It is
recommended that in applications with high interference, shielded twisted pair
(STP) cable is used. However, the shield itself does create a capacitance that
degrades the frequency response of the machines. For shorter distances, of
50m or so, shielded twisted pair (STP) cable is preferred because it provides
protection from interference (degradation is non apparent). For a long range
application, unshielded twisted pair (UTP) cable is preferred. However, the
unshielded twisted pair (UTP) cable should be installed far away from electric
cables, motors and so on, which are prone to create electrical interference.
3.3 About the VP-300THD 1:2 XGA/HD DA/CAT5 Transmitter
Your Kramer TOOLS VP-300THD is a high performance distributor that:
Accepts one computer graphics2 / HD3 input, provides necessary
buffering and isolation and then distributes the signal to two identical outputs,
as well as transmitting it over CAT5 UTP cable to its appropriate receiver4
Has a resolution of up to UXGA, with a transmission range of more than
300 ft. (more than 100 meters)
Includes the Power Connect feature (see section 3.1) and/or is 12VDC fed
3.4 Recommendations for Achieving the Best Performance
Achieving the best performance means:
Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables)
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality, and positioning your VP-300THD away
from moisture, excessive sunlight and dust
1 CAT5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
2 The terminology XGA is used throughout this manual, where this implies any RGBHV signal on an HD15 connector
having a resolution from VGA up to UXGA
3 The VP-300THD accepts high definition resolutions: 480p, 576p, 720p, 1080i, and 1080p
4 Note that the CAT5 connector excludes audio

5 Connecting the VP-300THD
You can use the VP-300THD and, for example, the TP-120 to configure an
XGA/HD DA/CAT5 Transmitter and Receiver system.
To connect the VP-300THD with the TP-120, as the example in Figure 5
illustrates, do the following:
1. On the VP-300THD 1:2 XGA/HD DA/CAT5 Transmitter, connect the:
Computer graphics (XGA / HD) source (for example, a computer) to the
INPUT HD15F connector
OUTPUT 1 and OUTPUT 2 HD15F connectors to up to1 two acceptors
(for example, to a display and to a projector, respectively)
2. On the TP-120 XGA Line Receiver, connect the XGA OUT HD15F
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 5.1.
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 switches2 on the underside
6. On the TP-120, if required:
Adjust3 the video output signal level and/or cable compensation
equalization level
Set the H SYNC and V SYNC switches4, on the underside
1 When both outputs are not required, connect only the output that is required and leave the other output unconnected
2 By default, both switches are set to the left (to NORMAL) to retain the VS and HS polarity
3 Use a screwdriver to carefully rotate the trimmer, adjusting the appropriate level
4 By default, both switches are set down (for normal V SYNC and H SYNC polarity)
