VS-21HDCP-IR - Getting Started

2 Getting Started

We recommend that you:

Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

Go to http://www.kramerelectronics.com 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 VS-21HDCP-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-21HDCP-IR

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

VS-21HDCP-IR. After connecting your VS-21HDCP-IR, connect its

power and then switch on the power to each device.

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

1. Connect up to two DVI sources to the INPUT connectors, as follows:

INPUT 1 connector to DVI source 1 (for example, a computer)

INPUT 2 connector to DVIsource 2 (for example, a set top box)

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

display).

3. Connect the 5V DC power adapter to the power socket and connect the

adapter to the mains electricity (not illustrated in Figure 2).

4. If required, connect a PC or controller to the RS-232 port (see Section 4.1).

5. Press the SELECT button to choose which DVI 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.

Alternatively you can press key 1 or 2 on the remote transmitter, once setup (see

Section 4.2), or use the contact closure remote control pins (see Section 4.3) or use

RS-232.

4.1 Controlling via RS-232

You can connect to the VS-21HDCP-IR via an RS-232 connection using, for

example, a PC. Note that a null-modem adapter/connection is not required.

To connect to the VS-21HDCP-IR via RS-232:

Connect the RS-232 9-pin D-sub rear panel port on the VS-21HDCP-IR unit

via a 9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin

5 need to be connected) to the RS-232 9-pin D-sub port on your PC
