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 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).
2.2 Safety Instructions ! 2.3 Caution: There are no operator serviceable parts inside the unit Warning: Use only the Kramer Electronics input power wall adapter that is provided with the unit Warning: Disconnect the power and unplug the unit from the wall before installing 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.
3 Overview The high-quality VM-114H 2x Input 1:4 HDMI DA is a switcher/distribution amplifier for HDMI and TP (Twisted Pair) signals. It reclocks and equalizes one of two selectable input signals and distributes it to four identical HDMI outputs. In particular, the VM-114H features: A maximum data rate of 6.75 Gbps (2.25Gbps per graphic channel) (HDMI), 4.95Gbps (1.
You can daisy-chain up to six devices with the maximum overall distance between the first and last devices being cumulative and limited by the cable type used. 3.1 Using Twisted Pair Cable Kramer engineers have developed special 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 cable), and the Kramer: BC-DGKat7a23 (CAT 7a 23 AWG cable).

4 Connecting the VM-114H i Always switch off the power to each device before connecting it to your VM-114H. After connecting your VM-114H, connect its power and then switch on the power to each device. To connect the VM-114H as illustrated in the example in Figure 2: 1. Connect the HDMI source (for example, a DVD player) to the IN 1 (HDMI) connector. 2. Connect the CAT 5 TP source (for example, a PT-571 HDMI Line Transmitter, VM-114H2C or VM-1114H4C) to the IN 2 (CAT5) connector. 3.

5 Using the VM-114H 2x Input 1:4 HDMI DA This section describes how to acquire the EDID (see Section 5.1) and how to connect via RS-232 (see Section 5.3). 5.1 Selecting an Active Input To select an active input: 5.2 Press the INPUT SELECTOR button until the required INPUT LED lights Acquiring the EDID Each input on the VM-114H has a factory default EDID loaded in non-volatile memory (see Section 8). This lets you connect the power before having to connect one of the acceptors.
4. Press the EDID READ button. The relevant LEDs flash in a pattern for a few seconds as follows: Slowly and then no longer lights. The EDID was successfully read. Quickly and then no longer lights. The EDID was not read and the default EDID was stored. 5.2.1 Disabling/Enabling Deep Color Support You can disable EDID deep color support to prevent signal deterioration when using long twisted pair cables on INPUT 2. To disable deep color and acquire EDID: 1. Disconnect the power. 2.
5.4 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.

7 Default Communication Parameters The following table lists the default communication parameters for the VM-114H.
8 Default EDID The factory default EDID is listed below. Monitor Model name Manufacturer Plug and Play ID Serial number Manufacture date ------------------------EDID revision Input signal type Color bit depth Display type Screen size Power management Extension blocs ------------------------DDC/CI VM114H KRM KRM0114 505-707455010 2009, ISO week 10 1.3 Digital Undefined RGB color 520 x 320 mm (24.
9 Protocol 2000 This RS-232/RS-485 communication protocol uses four bytes of information as defined below. For RS-232, a null-modem connection between the machine and controller is used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit. Note: Compatibility with Kramer’s Protocol 2000 does not mean that a machine uses all of the commands below. Each machine uses a sub-set of Protocol 2000, according to its needs. 9.
When a single machine is controlled over the serial port, always set M4…M0 to 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1.
