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 int o tight coils

3 Overview
The high quality VM-114H2C 2 Input 1:4 HDMI DA/2x CAT5 Outputs is a
switcher/distribution amplifier for HDMI and TP (Twisted Pair) signals. It re c locks
and equalizes one of two selectable input signals and distributes it to two HDMI
and two TP outputs.
In particular, the VM-114H2C:
• Supports up to 2.25Gbps bandwidth per graphic channel (HDMI), 1.65Gbps
bandwidth per graphic channel (DGKat)
• Can read and store in non-volatile memory the defaul t EDID or the EDID
1
block from one or a mix

• Features I-EDIDPro™ Kramer Intelligent EDID Processing™ – Intelligent
EDID hand ling & pr ocessing algorithm ensur es Plug and Play operatio n for
HDMI systems
of the output display devices, so it can then
provide the EDID information to the source even if the displ ay device is not
connected
• Supports HDMI (V1.4 w 3D, Deep Color
3
• Is HDCP compliant
, x.v.Color™ and 7.1
uncompressed audio channels (Dolby TrueHD, DTS-HD))
• Features LEDs indicating the selected input and active output
• Supports IR remote control and has a remote IR 3.5mm mini jack
• Is 12V DC fed and is housed 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
1 EDID is Extended Display Identification Data
2 The EDID acquired is a weighted average of all the connected outputs For example, if several displays with different resolutions are
connected to the outputs, the acquired EDID supports all the resolutions, as well as other parameters included in the EDID

3.1 Using Shielded Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair pr oducts; the Kramer: BC-DGKat524 (CAT 5 24 AWG) , the
Kramer BC-DGKat623 (CAT 6 23 AWG), and the Kramer BC-DGKat7a23 (CAT
7a 23 AWG) cables. 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 the transmitter needs to be
connected to a power source when the devices are within 90m (270ft) of each
other. The Power Connect™ feature applies as long as the cable can carry power.
The distance does not exceed 90m on standard CAT 5 cable. For longer dis tances,
heavier gauge cable should be used
1
!
.
Warning:
Using a TP cable that is incorrectly wired will
cause permanent damage to the device
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
