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 Go to www.kramerav.com/downloads/VM-4UHD to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate). 2.
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 Kramer TOOLS® VM-4UHD is a high-quality 1:4 HDMI distributor that takes one HDMI input, equalizes and reclocks the signal and distributes it to four identical outputs. The VM-4UHD distributes signals having resolutions up to 4Kx2K and including WUXGA and 1080p. In particular, the VM-4UHD features: A maximum data rate of 10.2Gbps (3.4Gbps per graphic channel) HDMI support for Deep Color, x.v.
3.1 Defining the VM-4UHD 1:4 HDMI DA This section defines the VM-4UHD. Figure 1: VM-4UHD 1:4 HDMI DA # Feature Function 1 PROGRAM USB Connector Connect to a PC to perform firmware upgrades (via K-Upload) and work with the EDID Designer K-Upload and EDID Designer can be downloaded from our Web site at: www.kramerav.com/downloads/) 2 EDID SETUP Button Press to capture the input EDID or select the default EDID (see Section 4.
4 Connecting the VM-4UHD Always switch off the power to each device before connecting it to your VM-4UHD. After connecting your VM-4UHD, 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. Connect the VM-4UHD as illustrated in the example in Figure 2: 1. Connect an HDMI input source (for example, a DVD player) to the HDMI IN connector. 2.

4.1 Acquiring an EDID To acquire an EDID, press the EDID SETUP button as follows: 1. The first press of the EDID SETUP button displays the present EDID status similar to that shown in the next step. 2. The second press of EDID SETUP enters the read mode and each additional press cycles through the source options: OUT 1 -> OUT 2 -> OUT 3 -> OUT 4 -> all LEDs flash for a default EDID. 3. When the desired EDID source is reached, release the EDID SETUP button. The VM-4UHD reads the EDID for a few seconds.

7 Protocol 3000 The VM-4UHD can be operated using serial commands from a PC, remote controller, or touch screen. The unit communicates using the default Kramer Protocol 3000. This section describes: 7.1 Kramer Protocol 3000 syntax (see Section 7.1) Kramer Protocol 3000 commands (see Section 7.
7.1.1.2 Command String Formal syntax with commands concatenation and addressing: 7.1.2 Start Address Body Delimiter # Destination_id@ Command_1 Parameter1_1,Parameter1_2,…| Command_2 Parameter2_1,Parameter2_2,…| Command_3 Parameter3_1,Parameter3_2,…| CR Device Message Format Start Address (opt) Body Delimiter ~ Sender_id@ Message CR LF 7.1.2.
Message starting character '#' - For host command/query '~' - For machine response or machine command performed by keystroke operation on the front panel or IR remote controller. Device address (Optional when directly connected to the device) K-Net Device ID or MACHINE NUMBER followed by '@' (ex. #02@CR LF ) Query sign '?' follows some commands to define a query request. All outputs sign '*' defines all outputs.
7.1.5 Bidirectional Definition All commands are bidirectional. That is, if the device receives the code, it performs the instruction. If the instruction is performed (due to a keystroke operation on the front panel or IR controller) these codes are sent to the PC or other RS-232 / Ethernet / USB controller. 7.1.6 Command Chaining Multiple commands can be chained in the same string. Each command is delimited by a pipe character ('|').
