3| SD LED (Red)| Lights when the SDI signal is SD

Standard Definition (SD) means an NTSC or PAL compatible video format, consisting of 480i or 480p (for NTSC), or 576i or 576p (for PAL) of interlacedor progressivevideo format

4| LOCK LED (Green)| Lights when the VM-4UX has detected the input signal and was able to lock on that signal
5| ON LED (Green)| Lights when receiving power
6| INPUT BNC connector| Connect to the SDI source
7| OUT BNC connectors| Connect to the SDI acceptors (from1 to 4)

OUT1 + OUT 2 and OUT 3 + OUT 4 are both paired outputs

8| SVDC| +5V DC connector for powering the unit

Step 3: Install the VM-4UX
Install VM-4UX using one of the following methods

• Attach the rubber feet and place the unit on a flat surface.
• Fasten a bracket (included) on each side of the unit and attach it to a flat surface. For more information go to www.kramerav.com/downloadsVM-4UX
• Mount the unit in a rack using an optional RK-3T rack adapter.

Step 4: Connect the inputs and outputs
Always switch OFF the power on each device before connecting it to your VM- 4UX. For best results, we recommend that you
always use Kramer high-performance cables to connect AV equipment to the VM- 4UX.

For best results, when only one of the paired outputs (OUT 1+OUT 2 and OUT 3+OUT 4) is connected, cover its pair connector with a 750 terminator (supplied). For example, if only OUT 1 is connected, cover OUT 2 with a terminator (OUT 3 and OUT 4 do not need to be covered).

Step 5: Connect the power
Connect the 5V DC power adapter to VM-4UX and plug it into the mains electricity.

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-4UX to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).

Achieving the Best Performance

To achieve the best performance

• Use only good quality connection cables (we recommend Kramer high-performance, high-resolution cables) to avoid interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables)
• Do not secure the cables in tight bundles or roll the slack into tight coils
• Avoid interference from neighbouring electrical appliances that may adversely influence signal quality
• Position your VM-4UX away from moisture, excessive sunlight and dust

This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.

Safety Instructions

Caution: There are no operator serviceable parts inside the unit
Warning: Use only the Kramer Electronics power supply 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. 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. For details of Kramer’s recycling arrangements in your particular country go to our recycling pages at www.kramerav.com/support/recycling/.

Overview

The VM-4UX is a compact and high performance 1:4 4K distributor for standard broadcast-grade SDI signals up to 12G transmitted data rate. It auto-adapts to the data rate of the SDI input signal, equalizes and re-clocks the signal to improve transmitted signal reach, and distributes the signal to two identical SDI outputs. In particular, the VM-4UX features:

• Reliable Connectivity – Coaxial broadcast-grade cables are reliably connected via lockable BNC connectors, preventing unintentional disconnection and resulting in fast and highly professional uncompressed SDI signal distribution deployments.

• Extended-reach Input Extension – Input signal equalization and output signal reclocking to gain extended-reach signal extension. Using Kramer high-quality coaxial SDI cables, supports extension of up to 80m (260ft) for 12G 4K signals.
  Reach depends on signal resolution, and quality of copper cable used. For further details, go to our website at www.kramerav.com/product/VM- 4UX. Reach extension performance may vary while using non-Kramer coaxial cables.

• SDI Signal Transmission – Auto-adapts to SDI, HD-SDI, 3G HD-SDI, 6G and 12G SDI compliant signals, supporting pass-through of standard embedded audio channels with ancillary ID and metadata information.

• Easy Installation and Maintenance – Compact TOOLS™ fan-less enclosure for small footprint spaces and over-ceiling mounting, or side-by-side mounting of 3 units in a 1U rack space with the optional RK-3T rack adapter. Status indicators for transmitted SDI data rate of input and output connected signals, and power indicator, for ease of maintenance and troubleshooting.

Connecting the VM-4UX

Always switch off the power to each device before connecting it to your VM- 4UX. After connecting your VM-4UX, 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.

1. Connect a 12G SDI video source (for example, a 12G SDI camera) to the INPUT BNC connector.
2. Connect up to four video OUT BNC connectors to the appropriate HD-SDI video acceptors (for example, 12G SDI displays).
   For best results, when only one of the paired outputs (OUT 1 + OUT 2 and OUT 3

• OUT 4) is connected, cover its pair connector with a 75Ω terminator (supplied). For example, if only OUT 1 is connected, cover OUT 2 with a terminator (OUT 3 and OUT 4 do not need to be covered).

  3. Connect the 5V DC power adapter to the power socket and connect the adapter to the mains electricity (not shown in Figure 2).
