Overview

3 Overview

The high quality Kramer VS-21HDCP-IR is an HDCP (High-Bandwidth

Digital Content Protection)1compatible 2x1 DVI Switcher that accepts two

DVI inputs—letting you select either DVI2

The VS-21HDCP-IR:

input using a pushbutton located

on the front panel—and routes the selected DVI input signal to the DVI output.

•Passes EDID/HDCP signals from source to display

The VS-21HDCP-IR lets you read and store, in non-volatile memory, the

EDID3

•Is 5V DC fed

block from one or both outputs, so it can then provide the EDID

information to the DVI source even if the display device is not connected.

•Can be controlled remotely via RS-232, the contact closure REMOTE

input select terminal block connector or the infrared remote control

transmitter

3.1 About HDCP

The High-Bandwidth Digital Content Protection (HDCP) standard4

3.2 Defining EDID

protects

digital video and audio signals transmitted over DVI or HDMI connections

between two HDCP-enabled devices to eliminate the reproduction of

copyrighted material. To protect copyright holders (such as movie studios)

from having their programs copied and shared, the HDCP standard provides

for the secure and encrypted transmission of digital signals.

The Extended Display Identification Data (EDID5

) is a data-structure,

provided by a display, to describe its capabilities to the source. The EDID

enables the VS-21HDCP-IR to “know” what kind of monitor is connected to

the output. The EDID includes the manufacturer’s name, the product type, the

timing data supported by the display, the display size, luminance data and (for

digital displays only) the pixel mapping data.

3.3 Recommendations for 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 and positioning

your VS-21HDCP-IR away from moisture, excessive sunlight and dust

5 Connecting a VS-21HDCP-IR 2x1 DVI Switcher

To connect the VS-21HDCP-IR 2x1 DVI Switcher, as illustrated in the

example in Figure 2, do the following2

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 DVI source 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

5.1

5. Press the SELECT button

1 No Null-modem adapter/Connector is required

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.

2 Switch OFF the power on each device before connecting it to your VS-21HDCP-IR. After connecting your

VS-21HDCP-IR, switch on its power and then switch on the power on each device

3 Alternatively you can press key 1 or 2 on the remote transmitter, once setup (see Section 5.2), or use the contact closure

remote control pins (see Section 5.3) or use RS-232

5.1 Controlling the VS-21HDCP-IR 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.

5.2 Using the Remote Control Transmitter

You can use the remote control transmitter1

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

following:

to switch INPUT 1 or 2 to the

output. Before doing so, set it to work with the VS-21HDCP-IR by assigning

a GROUP number.

1. Point the remote control transmitter at the remote receiver 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.

5.3 Controlling via the REMOTE Terminal Block Connector

The contact closure remote control pins operate in a similar way to the input

SELECT button. Using the contact closure remote control lets you select an

input by remote control. To do so, temporarily connect the required input

(IN1 or IN2) pin on the REMOTE terminal block connector to the G (ground)

pin, as illustrated in the examples in Figure 3.

DO NOT connect more than one PIN to the G PIN at the same time

To select IN1, attach PIN IN1 to the G PIN:

To select IN2, attach PIN IN2 to the G PIN

Figure 3: Connecting the REMOTE Input Select Connector

1 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
