VS-42UHD - Overview 5
You can control the VS-42UHD using the front panel buttons, or remotely via:
•RS-232 serial commands transmitted by a PC, touch screen system or other
serial controller
•The Kramer RC-IR3 infrared, remote control transmitter
•A PC connected via a LAN to the Ethernet port on the VS-42UHD
•An optional, external, remote IR receiver (see Section 3.1)
3.1 Using the IR Transmitter
You can use the RC-IR3 IR transmitter to control the machine via the built-in IR
receiver on the front panel or, instead, via an optional external IR receiver (for
example, P/N C-A35M/IRR-50). The external IR receiver can be located up to 15m
away from the machine. This distance can be extended to up to 60m when used
with three extension cables (for example, P/N C-A35M/A35F-50).
Before using the external IR receiver, be sure to arrange for your Kramer dealer to
insert the internal IR connection cable (for example, P/N: 505-70434010-S) with the
3.5mm connector that fits into the REMOTE IR opening on the rear panel. Connect
the external IR receiver to the REMOTE IR 3.5mm connector.

4 Connecting the VS-42UHD
Always switch off the power to each device before connecting it to
your VS-42UHD. After connecting your VS-42UHD, connect its
power and then switch on the power to each device.
You do not have to connect all the inputs and outputs, connect only
those that are required.
To connect the VS-42UHD, as illustrated in the example in Figure 3, do the
following:
1. Connect up to four HDMI sources, (for example, Blu-ray Disc players) to the
HDMI Input connectors.
2. Connect the two OUT HDMI connectors to up to two HDMI acceptors, (for
example, LCD displays with built-in speakers).
3. If required, connect a PC/controller to the RS-232 port (see Section 4.1)
and/or the Ethernet port (see Section 4.2).
4. Connect the power adapter to the device and plug the power adapter into
the mains electricity (not shown in Figure 3).
5. If required, acquire the EDID (see Section 6.1).

4.1 Connecting a Serial Controller via RS-232
To connect a serial controller to the VS-42UHD:
•From the RS-232 9-pin D-sub serial port on the serial controller connect:
Pin 2 to the TX pin on the VS-42UHD RS-232 terminal block
Pin 3 to the RX pin on the VS-42UHD RS-232 terminal block
Pin 5 to the GND pin on the VS-42UHD RS-232 terminal block
4.2 Connecting to the VS-42UHD via Ethernet
You can connect to the VS-42UHD via Ethernet using either of the following
methods:
•Directly to the PC using a crossover cable (see Section 4.2.1)
•Via a network hub, switch, or router, using a straight-through cable (see
Section 4.2.2)

Note: If you want to connect via a router and your IT system is based on IPv6,
speak to your IT department for specific installation instructions.
4.2.1 Connecting the Ethernet Port Directly to a PC
You can connect the Ethernet port of the VS-42UHD directly to the Ethernet port on
your PC using a crossover cable with RJ-45 connectors.
This type of connection is recommended for identifying the VS-42UHD
with the factory configured default IP address.
After connecting the VS-42UHD to the Ethernet port, configure your PC as
follows:
1. Click Start > Control Panel > Network and Sharing Center.
2. Click Change Adapter Settings.
3. Highlight the network adapter you want to use to connect to the device and
click Change settings of this connection.
The Local Area Connection Properties window for the selected network
adapter appears as shown in Figure 4.

6. Select Use the following IP Address for static IP addressing and fill in the
details as shown in Figure 6.
For TCP/IPv4 you can use any IP address in the range 192.168.1.1 to
192.168.1.255 (excluding 192.168.1.39) that is provided by your IT
department.

4.2.2 Connecting the Ethernet Port via a Network Hub or Switch
You can connect the Ethernet port of the VS-42UHD to the Ethernet port on a
network hub or using a straight-through cable with RJ-45 connectors.
4.3 Connecting the Remote Contact-Closure Switches
You can connect up to four remote, contact-closure switches per output to control
the VS-42UHD remotely. These switches replicate the Input selection buttons on
the front panel of the VS-42UHD.

14 VS-42UHD - Principles of Operation
5 Principles of Operation
This section describes the operating theory of the VS-42UHD and includes:
•Automatic signal detection (see Section 5.1)
•Input switching modes (see Section 5.2)
•EDID operation (see Section 5.3)
5.1 Automatic Signal Detection
The VS-42UHD can automatically detect the presence of a video signal on an input
based on the presence of a video sync or clock signal.
5.2 Input Switching Modes
5.2.1 Manual Mode
In Manual switching mode, routing is performed according to the front panel button
selection or according to the remote command selection.
5.2.2 Automatic Mode
Automatic switching can be performed in either of the following ways:
•Input priority. Upon detection of an active input, the input with the highest
priority is automatically selected. Input priority is from the lowest input number
(1) to the highest (4)
•Last Connected. The device automatically selects the most recently
connected input. Should this source become inactive, the device
automatically switches to the last connected input that was active. When
turning the device on and more than one input is active, the input with the
highest priority is selected
If a manual selection is made when the device is in Automatic mode, the device
enters Manual Override mode. The manually selected input remains selected as
long as it is active. When a manually selected input becomes inactive, the device
returns to Automatic mode.

VS-42UHD - Principles of Operation 15
5.3 EDID Operation
The VS-42UHD has a default EDID (see Section 12) stored on all inputs. This EDID
can be exchanged for either:
•A custom EDID which is uploaded to one or more inputs using Protocol 3000
commands (see Section 13.3.5)
–OR–
•The EDID of a display device connected to an output by using either the
front panel buttons (see Section 6.2), a Protocol 3000 command, or the Web
pages
The EDID is non-volatile and the last valid EDID is used when the device is
powered up.
5.4 Step-in Functionality
The VS-42UHD can function as a step-in switcher when connected to a suitable
HDMI transmitter, (for example, the SID-X3N, DIP-30 or DIP-31) using the correct
HDMI cable with HEC support.
Use the Web pages (see Section 8.2.2) to assign remote device button actions.
The default button actions are shown in the following table. Up to three buttons can
be active at the same time.
