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

facility. For details of Kramer’s recycling arrangements in your particular country

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).
