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 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 product 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 VS-21DPIR - Overview
3 Overview
The VS-21DPIR is a high quality switcher for DisplayPort (DP) signals that accepts
two DP inputs—letting you select either DP input using a switch located on the
panel—and routes the selected DP input signal to the DP output.
In particular, the VS-21DPIR features:
•Uses up to four lanes at rates of 1.6Gbps or 2.7Gbps bandwidth per lane
•Features a maximum resolution of 2560x1600 pixels and a total maximum
data rate of 10.8Gbps over four lanes
•Is HDCP compliant and HDTV compatible
•Passes the EDID signals from the display device to the source
•Features high-resolution and rich colors, and the transport of audio and
multiple video streams
The VS-21DPIR is 5V DC fed and can be controlled remotely via the contact
closure REMOTE input select terminal block connector or the infrared remote
control transmitter.

4 Connecting the VS-21DPIR
Always switch off the power to each device before connecting it to your
VS-21DPIR. After connecting your VS-21DPIR, connect its power and
then switch on the power to each device.
To connect the VS-21DPIR, as the example in Figure 2 shows, do the following:
1. Connect up to two computer graphics sources to INPUT 1 and INPUT 2.
2. Connect the OUTPUT connector to the DisplayPort acceptor (for example, a
display), using the Kramer DisplayPort cable.
You can connect the DP output to an HDMI acceptor by using an appropriate adapter
and setting the DIP-switches.
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. Press the SELECT button to choose which DP 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 4.1), or use the contact closure remote control pins (see Section 4.1).

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-21DPIR 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-IR2 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 6 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.
4.2 Controlling via the REMOTE Terminal Block Connector
The contact closure remote control pins operate in a similar way to the output
SELECT button. Using the contact closure remote control lets you select an output
by remote control. To do so, temporarily connect the required input (OUT1 or
OUT2) pin on the REMOTE terminal block connector to the G (ground) pin, as
illustrated in the examples in Figure 3.
Caution: DO NOT connect more than one PIN to the G PIN
at the same time
To select OUT 1, attach PIN OUT1 to the
G PIN:
To select OUT 2, attach PIN OUT2 to the
G PIN:
