VM-4UX –Getting Started

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-4UX to check for up-to-date user

manuals, application programs, and to check if firmware upgrades are

available (where appropriate).

2.1 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.

2.2 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

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. For details of Kramer’s recycling arrangements in your particular country go

to our recycling pages at www.kramerav.com/support/recycling/.

VM-4UX –Overview

3 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.

Feature

Function

12G/6G LED (Blue)

Lights when the SDI signal is 12G or 6G

12G means a 2160p60 progressive video format

and 6G means a 2160p30 progressive video format

HD 1.5/3G LED

(Yellow)

Lights when the SDI signal is HD 1.5 or 3G

High Definition (HD) 1.5G means a 720p

progressive or 1080i interlaced video format and

3G means 1080p progressive video format

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 interlaced

or progressive video format

LOCK LED (Green)

Lights when the VM-4UX has detected the input

signal and was able to lock on that signal

ON LED (Green)

Lights when receiving power

4 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).
