VM-28H, VM-216H - 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 http://www.kramerelectronics.com/support/product_downloads.asp

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 neighboring electrical appliances that may adversely

influence signal quality

Position your Kramer VM-28H, VM-216H 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.

VM-28H, VM-216H - Overview

3 Overview

The Kramer VM-28H 2 Input 1:8 HDMI Distributor and VM-216H 2 Input 1:16

HDMI Distributor are high-quality distributors that accept one of two HDMI inputs

and distribute the signal to 8/16 outputs, allowing one or more of the outputs to be

connected to receiving devices, thus making them a versatile, reliable component

in a video system. The VM-28H/VM-216H distributes signals having resolutions up

to 1080p, including all HDTV formats.

Each high-quality HDMI Distributor accepts one of two HDMI inputs, and

distributes the selected signal to:

8 outputs (the VM-28H)

16 outputs (the VM-216H)

Both machines—the VM-28H and VM-216H:

Support up to 6.75Gbps (2.25Gbps per graphic channel)

Suitable for resolutions up to 1080p, and for all HD resolutions.

Can read and store, in non-volatile memory, the EDID block, for each input

separately, from an output display device, so it can then provide the EDID

information to the HDMI source even if the display device is not connected

Let you acquire the EDID from one output, from several connected outputs

or acquire the default EDID for fast and efficient connection of the unit

Lets you use the EDID default value when no display from which to read the EDID is

connected.

Have a 19" 1U rack-mountable enclosure, and are fed from a 100-240 VAC

universal switching power supply

IR Receiver

The red LED is illuminated when receiving signals from the Kramer Infrared remote control transmitter

POWER Switch

Illuminated switch for turning the unit ON or OFF

IN 1 Button

Press to select source 1 and distribute this signal to the outputs (when the EDID button does not

illuminate). Also used for acquiring/changing the EDID (see Section 5.4)

Illuminates when selected and there is a signal, flashes when selected but there is no signal

Illuminates when configuring the EDID. When the EDID button does not illuminate the machine is in

Distribution mode (lets you distribute an input signal to the outputs)

LOCK Button

Press to engage/disengage the front panel switches

Illuminates when the front panel switches are locked, pressing another button causes the LOCK button to flash

once warning that you need to unlock to regain control via the front panel. The LOCK button also flashes (the

IN 1, IN 2 and EDID buttons do not flash at the same time) when the machine is busy (perhaps searching

between signals) and no operation is permitted. When powering up, the VM-28H/VM-216H front panel is

automatically locked

OUTPUT STATUS LEDs

LEDs light when an output(s) is connected and active; LEDs flash when selecting the EDID (see

Section 5.4) or when connecting a non-HDCP display while providing HDCP content to the

VM-28H

The specific OUTPUT STATUS LEDs flash when the outputs are not HDCP compatible

controller instead of using the front panel IR receiver

Covered by a cap. The 3.5mm connector at the end of the internal IR connection cable fits

through this opening.

Optional. Can be used instead of the front panel (built-in) IR receiver to remotely control the

machine (only if the internal IR connection cable has been installed)
