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

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.
