VM-4H2 - Introduction 1

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-4H2 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 highperformance, 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-4H2 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

VM-4H2 - Getting Started 3

3 Overview

The VM-4H2 is a distribution amplifier for 4K UHD HDMI 2.0 signals. The unit takes one HDMI input, equalizes and reclocks the signal and distributes it to four identical outputs. It distributes signals having resolutions up to 4K@60 (4:4:4) with HDMI 2.0 and HDCP 2.2.

The VM-4H2 features:

•

A maximum data rate of 17.82Gbps (5.94Gbps per graphic channel) that supports resolutions up to 4K @60Hz (4.4.4)

•

HDMI support for Deep Color, x.v.Color™, Lip Sync, HDMI Uncompressed

Audio Channels, Dolby TrueHD, DTS-HD, CEC

•

HDCP 2.2, HDMI 2.0 support

•

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-4H2 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

)

Connects to a 5V DC power supply

3.2 Setting the DIP-Switches

The VM-4H2 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

Note : Any time the DIP-switch settings are changed, the device must be powered off and on for the new settings to take effect.

VM-4H2 - Overview 5

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

Programming mode

DIP 1

OFF (up) Normal mode

HDCP Input

(MAC mode)

2

HDCP enabled

ON (down) Enable programming HDCP disabled

Force RGB

3

Force RGB

Normal mode

Lock Default

EDID

4

EDID not locked

EDID locked

The VM-4H2 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.

Note: 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.

3.3 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:

LED

Input LED

(per input)

Indication State

Flashes four times then stays on HDCP lost on input while running

Output LED Flashes twice quickly, repeatedly HDCP signal on input.

Output device does not support HDCP

Flashes slowly, repeatedly Input signal detected.

Output device has invalid EDID

Flashes twice quickly then twice slowly, repeatedly

HDCP signal on input.

Output device does not support HDCP and has invalid EDID

6 VM-4H2 - Overview

4 Connecting the VM-4H2

Always switch off the power to each device before connecting it to your VM-4H2 . After connecting your VM-4H2 , 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-4H2 , 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 four OUTPUT connectors to up to four 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)

 HDMI OUT 4 connector to HDMI acceptor 4 (for example, 4 K 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 Section 3.3

for the state of the LED indicators during and after powering on.

5 Upgrading the Firmware

To upgrade the VM-4H2 firmware:

1. Turn off the VM-4H2 . Set DIP-switch 1 On (down). Turn on the VP-4H2 .

2. Download and install the EPConsole application from the Koryo (Taiwan)

Web site.

3. Download and extract the latest version of the firmware from the Kramer

Web site to a disk location on your PC. The firmware includes three files with names ending in .h00, .h01, .h02. Make sure they all exist in the same folder.

4. Run EPConsole.

5. Select the COM port that attaches to the VM-4H2 .

6. Specify the downloaded firmware file ending with .h00 as the BANK0 file.

The program automatically loads the other two files in banks 1 and 2.

7. Press Program MCU icon (downward pointing green arrow) to install the new firmware:

VM-4H2 - Upgrading the Firmware 9

8. After the firmware successfully downloads:

(In case of failure, rerun the previous process.):

 Power off the unit.

 Disconnect the comm cable.

 Set DIP-switch 1 Off (up).

 Power on the VM-4H2 to load the new firmware and resume operation.
