3 Overview
The high quality VM-114H4C 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 four TP outputs.
In particular, the VM-114H4C:
• Supports up to 1.65Gbps bandwidth per graphic channel (DGKat) 1
• Can read and store in non-volatile memory the default EDID or the EDID 2
block from one or a mix
3
of the output display devices, so it can then
provide the EDID information to the source even if the display device is not
connected
• Features I-EDIDPro™ Kramer Intelligent EDID Processing™ – Intelligent
EDID handling & processing algorithm ensures Plug and Play operation for
HDMI systems
• Supports 3D Pass-through, Deep Color 4
, x.v.Color™ and uncompressed
audio channels (Dolby TrueHD, DTS-HD)
• Is HDCP compliant
• 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
3.1 Using Shielded 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.
The VM-114H4C supports a range of up to 90m (295ft) at 1080i/SXGA or up to
30m (98ft) at 1080p/UXGA on shielded BCP-DGKat524 cable; 90m (295ft) at
1080i or up to 70m (230ft) at 1080p/UXGA on shielded BCP-DGKat623 cable.
You can daisy-chain up to six devices with the maximum overall distance between
the first and last devices being cumulative and limited by the cable type used.
1 Suitable for resolutions up to UXGA at 60Hz and for all HD resolutions
2 EDID is Extended Display Identification Data (see Section 3.4 for a more detailed definition)
3 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
