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 VS-21H-IR 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.

4 Connecting the VS-21H-IR

Always switch off the power to each device before connecting it to your

VS-21H-IR. After connecting your VS-21H-IR, connect its power and

then switch on the power to each device.

To connect the VS-21H-IR as illustrated in the example in Figure 2:

1. Connect up to two HDMI sources to the INPUT connectors, using the Kramer

HDMI cables: INPUT 1 connector to HDMI source 1 (for example, DVD Player

1) and INPUT 2 connector to HDMI source 2 (for example, DVD Player 2).

2. Connect the OUTPUT connector to the HDMI acceptor (for example, a

plasma display), using the Kramer HDMI cable.

3. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity.

4. Press the SELECT button (or press key 1 or 2 on the remote transmitter,

once setup (see Section 4.1)) to choose which HDMI input to route to the

output. The SELECT button toggles between INPUT 1 and INPUT 2, lighting

the IN 1 LED when INPUT 1 is selected, or the IN 2 LED when IN 2 is

selected.

4.1 Using the Remote Control Transmitter

You can use the remote control transmitter to switch INPUT 1 or 2 to the output.

Before doing so, set it to work with the VS-21H-IR by assigning a GROUP number.

The setup parameters for the remote control transmitter are as follows: router number = 1

(default); group number = 11, single digit mode (default), video (default). For further details,

see the RC-IR3 user manual

To assign the GROUP number on the remote control transmitter, do the following:

1. Point the remote control transmitter at the remote receiver (item 10 in Figure

1) and press the GROUP key.

2. Press key 11.

This sets and saves the group number.

To switch INPUT 1 or 2 to the output via the remote control transmitter, press key

1 or 2.
