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 the video, audio, presentation, and broadcasting professional 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 • Review the contents of this user manual • Use Kramer high-performance, high-resolution cables • Use only the power cord that is supplied with this machine i 2.1 Go to http://www.kramerelectronics.com to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
3 Overview The VS-41H is a high-performance switcher for HDMI signals. It reclocks and equalizes the signal and switches one of the 4 inputs to a single HDMI output. In particular, the VS-41H features: • A maximum data rate of 6.75Gbps (2.25Gbps per graphic channel) • HDTV compatibility (suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions) • HDMI support with Deep Color, x.v.Color™, up to 7.
3.1 Defining EDID The Extended Display Identification Data (EDID) is a data-structure provided by a display, to describe its capabilities to a graphics card (that is connected to the display’s source). The EDID enables the VS-41H to “know” what kind of monitor is connected to the output. The EDID includes the manufacturer’s name, the product type, the timing data supported by the display, the display size, luminance data and (for digital displays only) the pixel mapping data.
• Benefits consumers by providing superior, uncompressed digital video quality via a single cable, and user-friendly connector HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-effective manner • Is backward-compatible with DVI (Digital Visual Interface) • Supports two-way communication between the video source (such as a DVD player) and the digital television, enabling new functionality such as automatic configuration

4 Installing in a Rack This section provides instructions for rack mounting the unit.
5 Connecting the VS-41H i Always switch off the power to each device before connecting it to your VS-41H. After connecting your VS-41H, connect its power and then switch on the power to each device. To connect the VS-41H 4x1 HDMI Switcher (as illustrated in Figure 3), do the following: 1. If required: Set the appropriate INPUTS to the DVD mode (see Section 6.1) Acquire the EDID (see Section 6.2) 2. Connect the HDMI sources as follows: You do not have to connect all the HDMI sources.

6 Operating the VS-41H This section describes: 6.1 • The PC mode and the DVD mode (see Section 6.1) • How to acquire the EDID (see Section 6.2) • How to control the machine via RS-232 (see Section 6.3) • How to control the machine via the ETHERNET port (see Section 6.
3. Keep pressing and holding the PANEL LOCK button for a few seconds and then release it. The LOCK button flashes. 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. Press an input to toggle between the PC mode (input button not illuminated) and the DVD mode (input button illuminated). 5. To exit this mode, press the PANEL LOCK button. 6.
To acquire or change the EDID of a new output display: 1. Connect the new output display device. 2. Press the EDID button. The INPUT buttons flash 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 Connecting via the RS-232 Port You can connect to the VS-41H to a PC or RS-232 controller using the RS-232 connection. Note that a null-modem adapter/connection is not required.
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. 5. Select the Internet Protocol (TCP/IP) and click the Properties Button (see Figure 4). Figure 4: Local Area Connection Properties Window 6. Select Use the following IP Address, and fill in the details as shown in Figure 5. 7. Click OK.
Figure 5: Internet Protocol (TCP/IP) Properties Window 6.4.2 Connecting the ETHERNET Port via a Network Hub (StraightThrough Cable) You can connect the Ethernet port of the VS-41H to the Ethernet port on a network hub or network router, via a straight through cable with RJ-45 connectors. 6.4.3 Configuring Several Units via the Ethernet Port To control several units via the Ethernet, connect each unit via the Ethernet port to the LAN port of your PC.

NOTE 9 – An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter associated with the instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an input or output greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine is being programmed via the front panel. Reception of this code by the switcher is not valid.
