VM-114H4C - Overview
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 4.95Gbps (1.65Gbps bandwidth per graphic channel)
(DGKat)
Can read and store in non-volatile memory 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
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.
Features I-EDIDPro™ Kramer Intelligent EDID Processing™ – Intelligent
EDID handling & processing algorithm ensures Plug and Play operation for
HDMI systems
Supports HDMI 3D Pass-through, Deep Color, 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
The VM-114H4C 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-114H4C - Overview

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.
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 90m (270ft) of each other. The Power Connect™ feature
applies as long as the cable can carry power and the distance does not exceed
90m on standard TP cable. (Heavier gauge cable may be used to extend the
Power Connect™ range).
Warning:
Using a TP cable that is incorrectly wired can cause
permanent damage to the device!

VM-114H4C - Using the VM-114H4C
5 Using the VM-114H4C
This section explains how to:
Acquire the EDID (Section 5.1)
Enable/disable deep color support (Section 5.2)
5.1 Acquiring the EDID
Each input on the VM-114H4C has a factory default EDID loaded (see Section 9).
This lets you connect the power before having to connect one of the acceptors.
The VM-114H4C reads the EDID, which is stored in the non-volatile memory.
You can acquire the EDID from:
This is usually done only once, when the machine is being set up in an installation. Once
acquired, the EDID is saved in non-volatile memory and further acquisition is not necessary.
One output (the relevant output LED flashes)
The default EDID (all output LEDs flash)
Up to four connected outputs using the Auto-mix Mode (all output LEDs light)
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.
To acquire the EDID:
1. Connect the output(s) from which you want to acquire the EDID.
2. Press the EDID SELECT button briefly. The last acquired EDID is indicated
by the lit LED (for example, if Output LED 2 is lit, the EDID acquired was
from Output 2).
The device enters the EDID programming mode.
3. Press the EDID SELECT button repeatedly until the required EDID is
indicated based on the patterns described above.
4. Press the EDID READ button.
The relevant LEDs flash in a pattern for a few seconds as follows:

Slowly and then no longer lights. The EDID was successfully read
Quickly and then no longer lights. The EDID was not read and the
default EDID was stored
5.2 Disabling/Enabling Deep Color Support
You can disable EDID deep color support to prevent signal deterioration when
using long twisted pair cables on INPUT 2.
To disable deep color and acquire EDID:
1. Disconnect the power.
2. Connect the output or outputs from which you want to acquire the EDID.
3. Connect the power while pressing the EDID READ button.
4. Perform steps 3 through 5 in Section 5.1.
To enable deep color and acquire EDID:
1. Disconnect the power.
2. Connect the output or outputs from which you want to acquire the EDID.
3. Connect the power while pressing the EDID SELECT button.
4. Perform steps 3 through 5 in Section 5.1.

VM-114H4C - RS-232, IR Control and Pass-through
6 RS-232, IR Control and Pass-through
The VM-114H4C can be controlled via RS-232 and infrared. Depending on how
the RS-232 and IR connections are configured dictates whether the device
responds to control signals or transparently pass them through to another receiver
or transmitter. Three examples of various configurations in Sections 6.2.1, 6.2.2
and 6.2.3 illustrate this functionality.
6.1 RS-232 Control and Pass-through Using the VM-114H4C
As shown in Figure 3, you can connect a PC (or other serial controller) directly to
the VM-114H4C to control the VM-114H4C.
The VM-114H4C also transparently passes bidirectional RS-232 signals over the
CAT 5 cable from the TP-573 transmitter to the TP-574 receiver. For example, a
PC connected to the RS-232 port on the TP-573 can control an RS-232-
controllable device (for example, a projection screen) connected to the TP-574.
Figure 4: VM-114H4C RS-232 Control and Pass-through

VM-114H4C - RS-232, IR Control and Pass-through

6.2 Local IR Control and IR Pass-through Using the
VM-114H4C
The VM-114H4C provides an IR sensor and a 3.5mm mini jack for connecting a
remote IR emitter or sensor. When the VM-114H4C is connected to suitable
transmitters and receivers (for example, the TP-573 and TP-574), the
VM-114H4C can act as a pass-through for IR control signals, allowing remote
control of multiple devices using multiple IR remote controllers.
When there is no IR sensor or emitter connected to the IR Remote 3.5mm mini
jack, all signals received by the IR sensor on the front panel are passed to the
transmitter and receiver bi-directionally over the CAT 5 cable allowing control of
remote devices.
When an IR sensor or emitter is connected to the IR Remote 3.5mm mini jack, the
connection between the IR sensor on the front panel and the IR on the
transmitter/receiver is broken so that any signal received by the IR sensor on the
front panel remains local to the VM-114H4C and controls only the VM-114H4C.
To control any device you need to use the appropriate IR remote controller, for
example, the Kramer remote controller controls Kramer devices, the LCD remote
controller controls the LCD display and so on, as shown in the following examples.
The following examples illustrate just three of the possible ways of connecting the
VM-114H4C to provide local and remote IR control.
