1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront video, audio, presentation, and broadcasting professionals on a daily basis.
2 Getting Started We recommend that you: Unpack the equipment carefully and save the original box and packaging materials for possible future shipment i 2.1 Review the contents of this user manual Go to http://www.kramerelectronics.com/support/product_downloads.asp to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
2.3 Recycling Kramer Products The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled. To comply with the WEEE Directive, Kramer Electronics has made arrangements with the European Advanced Recycling Network (EARN) and will cover any costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on arrival at the EARN facility.
3 Overview The VS-44HDCP is a high quality 4x4 DVI matrix switcher. It reclocks and equalizes the signals and can route any input to any or all outputs simultaneously. It accepts up to four DVI/HDMI (over DVI-D connector) inputs and routes the selected DVI input signal to any or all of four DVI/HDMI outputs. DVI-D (Digital). Note that only the digital signal (DVI D) is available on the DVI connector. In particular, the VS-44HDCP features: Up to 6.75Gbps data rate (2.
3.1 About Fast Switching Older display devices required a longer time between the loss of one digital signal and the introduction of another, as well as a physical disconnection of the interconnecting cable in order to be able to detect and adjust to the new video attributes and parameters. Normal switching, therefore, introduced a 5V signal disconnection along with a delay in switching. Many newer display devices, however, are now capable of “on-the-fly” switching.

4 Installing in a Rack This section provides instructions for rack mounting the unit.
5 Connecting the VS-44HDCP i Always switch off the power to each device before connecting it to your VS-44HDCP. After connecting your VS-44HDCP, connect its power and then switch on the power to each device. To connect the VS-44HDCP as illustrated in the example in Figure 3: 1. Connect up to four DVI sources (for example, DVD players and/or Blu-ray disc players) to the IN DVI connectors. 2. Connect the OUT DVI connectors to up to four DVI acceptors (for example, DVI and/or LCD displays). 3.

6 Operating the VS-44HDCP 4x4 DVI Matrix Switcher This section describes how to: 6.1 Route inputs to outputs (see Section 6.1) Disconnect outputs (see Section 6.2) Store and recall a setup (see Section 6.3) Changing the port switching speed (see Section 6.4) Set HDCP on or off (see Section 6.5) Switching between Protocol 2000 and Protocol 3000 (see Section 6.6) Lock and unlock the front panel (see Section 6.7) Acquire the EDID (see Section 6.
6.3 Storing and Recalling a Setup You can use the STO and RCL buttons to store up to eight setups and then recall them as illustrated in Figure 4. IN 1 is used for setup number 5 and OUT 1 is used for setup number 1. Figure 4: SELECTOR Buttons i The numbers (1 to 8) in Figure 4 that illustrate the corresponding store/recall configuration numbers are for the purpose of illustration only and do not actually appear on the buttons. To store a setup: 1. Set the device to the desired setup.
6.4 Changing the Port Switching Speed The switching speed can be set per port to any of the following: 3—Normal (default) 2—Fast 1—Extra fast To change the port switching speed: 1. Ensure that the device is in normal switching mode, (that is, not Store, Recall or EDID mode). 2. Press the RCL and EDID buttons at the same time. The RCL and EDID buttons flash, and the display indicates the switching speed mode of each port. IN 1, IN 2 and IN 3 are illuminated (red). 3.
To set the HDCP: 1. Turn the power off on the machine. 2. Press and hold the IN 1, IN 2 and LOCK buttons simultaneously and turn the power on while pressing these buttons (you will need more than one person to perform this step). The machine is set to the HDCP enable/disable mode. The input front panel buttons’ status indicates the HDCP state of each input: HDCP enabled (ON) on an input – that input button is illuminated HDCP disabled (OFF) on an input – that button is not illuminated 3.
6.7 Locking and Unlocking the Front Panel To prevent unintended tampering with the unit via the front panel buttons, lock your VS-44HDCP. To lock/unlock the VS-44HDCP: Press and hold the PANEL LOCK button on the front panel to toggle the locking/release of the front panel buttons 6.8 Acquiring the EDID You can acquire the EDID from: A single connected output to one or more of the four inputs (see Section 6.8.1) 6.8.1 Several sets of inputs and outputs (see Section 6.8.
6.8.2 Acquiring an EDID from Several Sets of Inputs and Outputs To acquire the EDID from several sets of inputs and outputs (for example, OUT 1 to IN 1 and OUT 4 to IN 3): 1. Connect the required acceptors to the outputs from which you want to acquire the EDID. 2. Press the EDID and STO buttons simultaneously and hold them for 3 seconds. Both buttons flash. 3. Press the SELECT IN button to which the first EDID is to be copied (for example, IN 1). The selected input number flashes on the display. 4.
6.8.3 Acquiring the Default EDID To store the default EDID on a selected input (for example, IN 2): 1. Press the EDID and STO buttons simultaneously and hold them for 3 seconds. Both buttons flash. 2. Press the SELECT IN button to which the EDID will be copied (for example, IN 2). The selected input number flashes on the display. 3. Press the OFF button until a "0" (zero) appears on the display. 4. Press the EDID button. The default EDID is stored on the selected input when the display returns to normal.
7 Controlling the VS-44HDCP You can control the VS-44HDCP via the RS-232 serial commands transmitted by a touch screen system, PC or other serial controller (see Section 7.1) 7.1 The Ethernet port (see Section 7.2) The Kramer infrared remote control transmitter (see separate user manual) The infrared remote extension cable transmitter (optional), see Section 7.3 Connecting to the VS-44HDCP via RS-232 You can connect to the VS-44HDCP via an RS-232 connection using, for example, a PC.
7.2.1 Connecting the Ethernet Port Directly to a PC You can connect the Ethernet port of the VS-44HDCP directly to the Ethernet port on your PC using a crossover cable with RJ-45 connectors. i 7.2.2 This type of connection is recommended for identifying the VS-44HDCP with the factory configured default IP address.

11 Protocol 3000 By default, the VS-44HDCP is set to Protocol 2000 (see Section 12) but is also compatible with Kramer’s protocol 3000 (see Section 11). i Note that the VS-44HDCP needs to be set to protocol 2000 in order to use the IR remote control. Section 9 describes how to switch between protocol 3000 and protocol 2000. The VS-44HDCP can be operated using serial commands from a PC, remote controller or touch screen using the Kramer Protocol 3000.
