VM-114H2C - 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-114H2C 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-114H2C - Overview

3 Overview

The VM-114H2C 2 Input 1:4 HDMI DA/2x CAT5 Outputs is a switcher/distribution

amplifier for HDMI and TP (twisted pair) signals. It reclocks and equalizes one of

two selectable input signals and distributes it to two HDMI and two TP outputs.

In particular, the VM-114H2C features:

A maximum data rate of 4.95Gbps (1.65Gbps per graphic channel),

6.75Gbps (2.25Gbps per graphic channel) maximum when using HDMI only

Non-volatile memory that reads and stores the default EDID or the EDID

block from one or a mix of the output display devices, so it can then provide

the EDID information to the source even if the display device is not

connected

I-EDIDPro™ Kramer Intelligent EDID Processing™, an intelligent EDID

handling & processing algorithm that ensures Plug and Play operation for

HDMI systems

HDMI support for 3D, Deep Color, x.v.Color™ and 7.1 uncompressed audio

channels (Dolby TrueHD, DTS-HD)

HDCP compliance

LEDs indicating the selected input and active output

IR remote control support and has a remote IR 3.5mm mini jack

12V DC power

Housing in a Kramer desktop enclosure

The VM-114H2C supports a range of:

Up to 90m (295ft) at 1080i, or up to 30m (98ft) at 1080p on shielded

BC-DGKat524 cable

Up to 90m (295ft) at 1080i, or up to 70m (230ft) at 1080p on shielded

BC-DGKat623 cable

Up to 100m (330ft) at 1080i or up to 90m (295ft) at 1080p on shielded

BC-DGKat7a23 cable

VM-114H2C - Overview

3.1 Using Twisted Pair Cable

Kramer engineers have developed special twisted pair cables to best match our

digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the

Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23

(CAT 7a 23 AWG cable). These specially built cables significantly outperform

regular CAT 5 / CAT 6 / CAT 7a cables.

3.2 About the Power Connect™ Feature

The Power Connect™ feature here means that only one unit in a system, the

transmitter or receiver, needs to be connected to a power source when the

devices are within 60m (197ft) of each other. The Power Connect™ feature

applies as long as the cable can carry power and the distance does not exceed

60m on standard TP cable. (Heavier gauge cable may be used to extend the

Power Connect™ range).

4 Connecting the VM-114H2C

Always switch off the power to each device before connecting it to your

VM-114H2C. After connecting your VM-114H2C, connect its power

and then switch on the power to each device.

To connect the VM-114H2C as illustrated in the example in Figure 2:

1. Connect the HDMI source (for example, a DVD player) to the IN 1 (HDMI)

connector.

2. Connect the TP source, for example, a PT-571 HDMI Line Transmitter

(another example is the TP-573), another VM-114H2C or a VM-114H4C to

the IN 2 (CAT5) connector.

3. Connect the HDMI OUT connectors to up to two HDMI acceptors, for

example, LCD TV or plasma displays

4. Connect the TP RJ-45 output connectors to up to two TP acceptors, for

example, the PT-572+ HDMI Line Receiver (another example is the TP-574),

the VM-114H or the VM-114H4C.

5. Optional—Plug the remote IR sensor into the front panel remote IR 3.5mm

mini jack.

6. Optional—Connect a PC via RS-232 to the RS-232 port on the VM-114H2C

(see Section 4.1).

7. Connect the power adapter to the power socket on the VM-114H2C and to

the mains electricity (not shown in Figure 2).

8. Optional—Press the EDID READ button to acquire or change the EDID

information (see Section 5.1).
