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
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer PT-102VN away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN

PT-102VN - Overview
3 Overview
The Kramer PT-102VN is a distribution amplifier for composite video or SDI
signals. It takes one input, provides correct buffering and isolation and distributes
the signal to two identical outputs. Specifically, the PT-102VN:
Accepts a single input and distributes it to 2 identical outputs using BNC
connectors
Has a bandwidth of 430MHz, ensuring that it remains transparent even in
the most critical applications
Has gain and equalization (EQ.) controls to compensate for cable losses
Is ideally suited to work with the Pico TOOLS™ PT-102AN 1:2 Audio DA

4 Connecting the PT-102VN
Always switch off the power to each device before connecting it to your
PT-102VN. After connecting your PT-102VN, connect its power and
then switch on the power to each device.
You can connect your PT-102VN:
As a 1:2 video DA (see Section 4.1)
To a 4x1VB 4x1 High Resolution Video Switcher to increase the number of
inputs (see Section 4.2)
To two 105VB 1:5 High Resolution Video DA units to increase the number of
outputs (see Section 4.3)
4.1 Connecting the PT-102VN 1:2 Video DA
To connect the PT-102VN 1:2 Video DA, as the example in Figure 2 illustrates,
connect the following:
1. Connect a composite video source (for example, a composite video player)
to the INPUT BNC connector.
2. Connect the two OUT BNC connectors to up to two composite video
acceptors, as follows:
Connect the OUT 1 connector to video acceptor 1 (for example, a
projector)
Connect the OUT 2 connector to video acceptor 2 (for example, a
display)
3. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
4. If required, adjust the output signal level and/or cable compensation
equalization level.

4.2 Increasing the Inputs
When it is necessary to handle more than one input, you can increase the number
of inputs for example, from one to four, by connecting the Kramer 4x1VB 4x1 High
Resolution Video Switcher (a mechanical switcher that lets you select any input to
route to one output via its INPUT SELECTOR buttons. Alternatively, you could
connect the PT-102VN to a video switcher with more than four inputs) in addition
to the PT-102VN 1:2 Video DA, as the example in Figure 3 illustrates:
1. Connect up to four sources to the four IN connectors of the 4x1VB.
2. Connect the OUTPUT connector of the 4x1VB to the INPUT connector of
the PT-102VN.
3. Connect the OUT connectors of the PT-102VN to up to two acceptors.
4. Select the desired input via the INPUT SELECTOR switch of the 4x1VB.
5. Connect the 12V DC power adapter to the power socket of the PT-102VN
and connect the adapter to the mains electricity.

6. Adjust the output signal level and/or cable compensation equalization level
of the PT-102VN, if required.
Figure 3: Increasing the Inputs - Connecting a 4:2 DA
4.3 Increasing the Outputs
The PT-102VN can be cascaded with other high quality distribution amplifiers to
distribute a video source to more than two outputs. For example, you can increase
the number of outputs from two to ten, by connecting a PT-102VN 1:2 Video DA
unit to two Kramer 105VB 1:5 High Resolution Video DA units, forming a 1:10 DA,
as the example in Figure 4 illustrates:
To form a 1:10 DA, do the following:
1. Connect a source to the INPUT BNC connector of the PT-102VN.
2. Connect the OUT 1 BNC connector of the PT-102VN to the INPUT BNC
connector of the first 105VB.
3. Connect the OUT 2 BNC connector of the PT-102VN to the INPUT BNC
connector of the second 105VB.
4. Connect the five OUT BNC connectors of the first 105VB to the video
acceptors 1 to 5, and connect the five OUT BNC connectors of the second
105VB to five video acceptors as well.
5. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (for the PT-102VN and both 105VB units).
