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 i 2.1 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 Shielded Twisted Pair Kramer engineers have developed special shielded twisted pair cables to best match our digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the Kramer BC-DGKat623 (CAT 6 23 AWG), and the Kramer BC-DGKat7a23 (CAT 7a 23 AWG) cables. These specially built cables significantly outperform regular CAT 5/CAT 6 /CAT 7a cables.
2.5 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 high quality VM-1H4C is a distribution amplifier for HDMI, IR and bidirectional RS-232 signals over TP (Twisted Pair) cable. It reclocks and equalizes the input signal and distributes it to four TP outputs simultaneously. More specifically, the VM-1H4C: Supports up to 4.95Gbps data rate (1.
4 Defining the VM-1H4C 1:4 HDMI Over CAT 5 DA The VM-1H4C encodes the HDMI, IR and RS-232 signals and transmits them over TP cable to a compatible receiver (for example, the Kramer TP-574 HDMI/RS-232/ IR Line Receiver). Figure 1 defines the front and rear panels of the VM-1H4C.

5 Connecting the VM-1H4C i Always switch off the power to all devices before connecting them to your VM-1H4C. Figure 2: Connecting the VM-1H4C ! Warning: Using a TP cable that is incorrectly wired may cause permanent damage to the device To connect the VM-1H4C as illustrated in the example in Figure 2: 1. Connect the HDMI source, (for example, a DVD player) to the Input (HDMI) connector. 2. Connect the TP RJ-45 outputs to up to four TP acceptors, (for example, TP-574).
3. Connect the front panel remote IR 3.5mm mini jack to the IR device, (for example, an IR emitter). Note: All data is passed simultaneously to all four TP outputs. 4. Optional—Connect to a serial controller, (for example, a computer) to the RS-232 9-pin D-sub connector. 5.
6 Acquiring the EDID The VM-1H4C is programmed with a default EDID (see Section 9). This lets you connect the power before having to connect one of the acceptors. To change this default EDID, you must acquire the new EDID from a display device.
7 Wiring the Twisted Pair RJ-45 Connectors When using STP cable, connect/solder the cable shield to the RJ-45 connector shield. Figure 3 defines the TP pinout using a straight pin-to-pin cable with RJ-45 connectors. i Note, that the cable Ground shielding must be connected/soldered to the connector shield.
