4	VS-42UHD - Overview

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)

3.1Using 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).

4.1Connecting 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

4.2Connecting 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.

4.2.1Connecting 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.

Figure 4: Local Area Connection Properties Window

10	VS-42UHD - Connecting the VS-42UHD

4.Highlight Internet Protocol Version 4 (TCP/IPv4) by clicking on the item.

5.Click Properties.

The Internet Protocol Properties window appears as shown in Figure 5.

Figure 5: Internet Protocol Version 4 Properties Window

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.

4.2.2Connecting 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.

4.3Connecting 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.

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)

5.1Automatic 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.

5.2Input Switching Modes

5.2.1Manual Mode

In Manual switching mode, routing is performed according to the front panel button selection or according to the remote command selection.

5.2.2Automatic 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.

14	VS-42UHD - Principles of Operation

5.3EDID 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.

5.4Step-in Functionality

The VS-42UHD can function as a step-in switcher when connected to a suitable HDMI transmitter, (for example, the SID-X3N 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.

	Command	Action
	Echo	Allows a connected controller to be programmed to perform a variety of
		tasks triggered by the user buttons, such as, room control, (lights,
		screen, and so on)
	Out1	Step in current input to Output 1
	Out2	Step in current input to Output 2

6Operating the VS-42UHD 4x2 HDMI Matrix Switcher

This section describes operating the VS-42UHD and consists of:

•Switching an input to an output (see Section 6.1)

•Acquiring an EDID from an output (see Section 6.2)

•Muting and unmuting the outputs (see Section 6.3)

•Locking and unlocking the front panel buttons (see Section 6.4)

•Generating a test pattern (see Section 6.5)

6.1Switching an Input to an Output

To switch an input to an output, (for example, Input 4 to Output 2):

•Press the Input 4 button in the bottom Output (To OUT 2) row. The LED lights red and Input 4 is switched to Output 2

6.2Acquiring an EDID from an Output

You can acquire the EDID from OUT 1 or OUT 2 and copy it to any or all of the four inputs to be stored in non-volatile memory. You can also reset any or all of the inputs to the default EDID.

To copy the EDID from an Output to one or more Inputs:

1.Press the EDID button to enter the EDID setting mode.

The EDID button lights.

Note: If there is no button activity for 10 seconds, the device automatically exits the EDID setting mode to normal operation, the EDID button no longer lights and any changes made are lost.

2.From the To OUT 1 (top) row, press each of the Inputs to which you want to copy the EDID from Output 1.

Each selected Input LED lights.
