5 Connecting a VS-41HDCP 4x1 DVI Switcher
Always switch off the power to each device before connecting it to your
VS-41HDCP. After connecting your VS-41HDCP, connect its power
and then switch on the power to each device.
To connect the VS-41HDCP 4x1 DVI Switcher (as illustrated in Figure 3), do the
following:
1. Connect up to four computer graphics sources to the inputs (1 to 4).
You do not have to connect all the DVI sources.
2. Connect the OUTPUT DVI connector to a DVI acceptor (for example, a
display).
3. If required, connect a PC and/or controller to the RS-232 port and/or the
ETHERNET port (see Section 6.4).
4. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 3).
5. If required, acquire the EDID (see Section 6.1).
Press an INPUT SELECTOR button (from 1 to 4) to choose which DVI input to
route to the output.

5.1 Connecting to the VS-41HDCP via RS-232
You can connect to the VS-41HDCP 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-41HDCP via RS-232:
Connect the RS-232 9-pin D-sub rear panel port on the VS-41HDCP 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

VS-41HDCP - Operating the VS-41HDCP
6 Operating the VS-41HDCP
This section describes how to:
Operate the PC and DVD modes (see Section Section 6.1)
Acquire the EDID (see Section 6.2)
Control the machine via the REMOTE terminal block connector (see
Section 6.3)
Control the machine via the ETHERNET port (see Section 6.4)
Control the machine via the Web pages (see Section 6.5)
6.1 The PC and DVD Modes
The VS-41HDCP has two operation modes that are specific per input: the PC
mode (which is the factory default) and the DVD mode. The PC mode is used
when connecting a computer or several computers to one or more of the inputs.
The DVD mode is used when connecting a DVD or several DVDs to the inputs.
The PC mode and the DVD mode can be applied to a single input or to several
inputs. For example, if you want to connect a computer to INPUT 1, another
computer to INPUT 2, and DVD machines to INPUT 3 and INPUT 4, set INPUT 1
and INPUT 2 to the PC mode and INPUT 3 and INPUT 4 to the DVD mode.
To set the inputs to either the PC or DVD mode, do the following:
1. Turn off the POWER.
2. Press the PANEL LOCK button while turning the POWER on again.
3. Keep pressing and holding the PANEL LOCK button for a few seconds and
then release it.
The LOCK button blinks.
If an input button illuminates, this indicates that that input is set to the DVD
mode.
If an input button is not illuminated, this indicates that that input is set to the
PC mode.

4. Toggle between the PC mode (input button not illuminated) and the DVD
mode (input button illuminated) by pressing that input.
5. Press the PANEL LOCK button to exit this mode.
The following table summarizes the differences between the PC mode and the
DVD mode:
PC Mode
DVD Mode
The input is connected to a computer
The input is connected to a multimedia
application, such as a DVD, a set top box and
so on
The EDID is available at all times (to
prevent computer reset)
The EDID is available only when that input is
connected to an output
The input EDID source is the default EDID
or an acquired EDID (see Section 6.1)
The input EDID source is acquired directly from
the connected output
Note, that even if an input is set to the PC mode, you can connect a DVD player to
that input and vice versa, a PC can be connected to an input that was set to the
DVD mode.
6.2 Setting the EDID
You can acquire or change the EDID (see Section 6.2.1) or reset the machine to
the default EDID (see Section 6.2.2).
If the connected output (for which EDID has already been acquired) is
disconnected, the EDID button blinks and then ceases blinking when reconnecting
the same output. When a new output is connected the EDID button blinks to
indicate that new EDID information must be acquired.

VS-41HDCP - Operating the VS-41HDCP
6.2.1 Acquiring / Changing the EDID
You can work with the default EDID or acquire or change an EDID via the
connected output. Use the EDID button to acquire the output EDID information.
To acquire or change the EDID of a new output display:
1. Connect the power supply.
2. Connect the new output display device.
The EDID button blinks.
3. Press the EDID button.
The INPUT buttons blink in sequence until the EDID is acquired.
6.2.2 Resetting the Default EDID
To reset the default EDID, disconnect the output and repeat the steps in
Section 6.2.1.
6.3 Controlling via the REMOTE Terminal Block Connector
The contact closure remote control pins operate in a similar way to the INPUT
SELECTOR button. Using the contact closure remote control you can select the
DVI input. To do so, momentarily connect the required input pin (IN 1, IN2, IN 3 or
IN 4) on the REMOTE terminal block connector to the GND (Ground) pin, as
Figure 4 illustrates.
DO NOT connect more than one PIN to the GND PIN at the same
time.

6.4 Controlling the VS-41HDCP via the ETHERNET Port
You can connect the VS-41HDCP via the Ethernet, using a crossover cable (see
Section 6.4.1) for direct connection to the PC or a straight through cable (see
Section 6.4.2) for connection via a network hub or network router.
6.4.1 Connecting the ETHERNET Port directly to a PC (Crossover
Cable)
Youcan connect the Ethernet port of the VS-41HDCP to the Ethernet port on your
PC, via a crossover cable with RJ-45 connectors.
This type of connection is recommended for identification of the factory
default IP address of the VS-41HDCP during the initial configuration.
After connecting the Ethernet port, configure your PC as follows:
1. Right-click the My Network Places icon on your desktop.
2. Select Properties.
3. Right-click Local Area Connection Properties.
4. Select Properties.
The Local Area Connection Properties window appears.
