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

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).
