VM-3H2 –Introduction

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. In recent years, we have

redesigned and upgraded most of our line, making the best even better!

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-3H2 to check for up-to-date user manuals,

application programs, and to check if firmware upgrades are available (where appropriate).

Achieving 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 neighboring electrical appliances that may adversely influence

signal quality.

•Position your Kramer VM-3H2 away from moisture, excessive sunlight and dust.

Safety Instructions

Caution:

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

equipment that is installed inside a building.

•For products with relay terminals and GPI\O ports, please refer to the permitted rating

for an external connection, located next to the terminal or in the User Manual.

•There are no operator serviceable parts inside the unit.

Warning:

•Use only the power cord that is supplied with the unit.

•Disconnect the power and unplug the unit from the wall before installing.

•Do not open the unit. High voltages can cause electrical shock! Servicing by qualified

personnel only.

•To ensure continuous risk protection, replace fuses only according to the rating

specified on the product label which located on the bottom of the unit.

VM-3H2 –Overview

Overview

Congratulations on purchasing your Kramer VM-3H2 1:3 4K HDR HDMI DA. VM-3H2 is a 1:3

distribution amplifier for up to 4K HDR, HDMI™signals, that comply with HDCP 2.2 content

protection standard. The unit takes one HDMI input, equalizes and reclocks the signal and

distributes it to three identical outputs.

The VM-3H2 features:

•A maximum data rate of 17.82Gbps (5.94Gbps per graphic channel) that supports

resolutions up to 4K @60Hz (4.4.4).

•HDR, HDCP 2.2 compliant signal, supporting deep color, x.v.Color™, lip sync, 7.1 PCM,

Dolby TrueHD, DTS-HD, CEC (OUT 1 only), 2K, 4K, and 3D as specified in HDMI 2.0.

•Kramer Equalization & re-Klocking™ Technology that rebuilds the digital signal integrity

to travel longer distances.

•A default EDID for fast and efficient connection of the unit.

The default EDID feature lets you connect the VM-3H2 without having to connect a

display to the output.

•Operating modes selectable by DIP-switch: force RGB, lock EDID, HDCP enable,

programming mode.

•3D pass-through.

•Plug and Play operation.

•Cascade of Kramer devices like distribution amplifiers.

•An RS-232 port for upgrading firmware.

•A compact MegaTOOLS®enclosure with a 5V DC power source.

Typical Applications

VM-3H2 is ideal for the following typical applications:

•Digital signage, entertainment, retail.

•Medical and defense applications that require high resolution support.

Setting the DIP-Switches

The VM-3H2 uses four DIP-switches to set four different operation modes:

•Programming mode –normal operation mode, programming mode.

•MAC mode –enable HDCP, disable input HDCP.

•Force RGB - force RGB, normal operation mode.

•Lock default EDID –locked, not locked.

Any time the DIP-switch settings are changed, the device must be powered off and on for the

new settings to take effect.

Kramer Electronics Ltd.

VM-3H2 –Defining the VM-3H2 1:3 4K HDR HDMI DA

To select the operation mode, set the DIP-switches as follows:

Programming

HDCP Input

(MAC mode)

Force RGB

Lock Default EDID

DIP

OFF (up)

Normal mode

HDCP enabled

Force RGB

EDID not locked

ON (down)

Enable programming

HDCP disabled

Normal mode

EDID locked

The VM-3H2 toggles between “Normal” and “Force RGB” modes.

In “Force RGB” mode, the read EDID is rewritten to identify only RGB support.

•To force RGB, set DIP 3 OFF (up).

•After setting Force RGB mode you must re-acquire the EDID to update the Force RGB

change.

Powering on the device identifies the mode as follows:

•In “Normal mode” (meaning no forcing RGB), the LEDs flash once.

•In “Force RGB mode”, the LEDS flash four times.

Force RGB modifies the EDID saved on the input to not support YUV format.

In case of a pink display, use the Force RGB mode.

LED Indications

The input and output LEDs turn on only when there is an input signal and an active output

device connected.

Flashing LEDs indicate the following states:

VM-3H2 –Mounting VM-3H2

Mounting VM-3H2

This section provides instructions for mounting VM-3H2. Before installing, verify that the

environment is within the recommended range:

•Operation temperature –0to 40C (32 to 104F).

•Storage temperature –-40to +70C (-40 to +158F).

•Humidity –10% to 90%, RHL non-condensing.

Caution:

•Mount VM-3H2 before connecting any cables or power.

Warning:

•Ensure that the environment (e.g., maximum ambient temperature & air flow) is

compatible for the device.

•Avoid uneven mechanical loading.

•Appropriate consideration of equipment nameplate ratings should be used for avoiding

overloading of the circuits.

•Reliable earthing of rack-mounted equipment should be maintained.

To mount the VM-3H2 on a rack

Mount the unit in a rack using the recommended rack adapter

(see www.kramerav.com/product/VM-3H2)

To mount the VM-3H2 on a table or shelf

•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.

VM-3H2 –Connecting the VM-3H2

Connecting the VM-3H2

Always switch off the power to each device before connecting it to your VM-3H2. After

connecting your VM-3H2, 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.

To connect the VM-3H2, as illustrated in the example in Figure 2, do the following:

1. Connect an HDMI input source (for example, a 4K Blu-ray player) to the HDMI IN

connector.

2. Connect the three OUTPUT connectors to up to three HDMI acceptors, as follows:

Not all outputs need to be connected.

▪HDMI OUT 1 connector to HDMI acceptor 1 (for example, a 4K display with

speakers).

▪HDMI OUT 2 connector to HDMI acceptor 2 (for example, a 4K display with

speakers).

▪HDMI OUT 3 connector to HDMI acceptor 3 (for example, 4K plasma display).

3. Connect the 5V DC power adapter to the power socket unit and then connect the

adapter to the mains electricity (not shown in Figure 2).

See LED Indications on page 5for the state of the LED indicators during and after

powering on.

VM-3H2 –EDID Acquisition Policy

EDID Acquisition Policy

This section describes the EDID policy as a function of the state of DIP-switch 4 (Lock Default

EDID).

When set to ON (down), the input EDID is locked to the default EDID value.

When set to OFF (up):

•If no outputs are connected when powering on the VM-3H2, the default EDID is set on

the input. The EDID of the first output that is connected after powering the device is set

to the input. This EDID is replaced by the default EDID only when all outputs are

disconnected.

•If one or more outputs are already connected when powering on the VM-3H2, the valid

EDID of the display that is connected to the output with the highest number is set to the

input (for example, if OUT 2 and OUT 3 are connected and both have valid EDIDs, when

powering the device, the EDID of the display connected to OUT 3 is written to the input).

DIP-switch changes take effect only after powering on the device.
