•Provides a simple
:
3interface between any audio/video source, such as a set-
top box, DVD player, or A/V receiver and video monitor, such as a digital
flat LCD/plasma television (DTV), over a single lengthy4
•Supports standard, enhanced, high-definition video, and multi-channel
digital audio
cable
5
•Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
on a single cable
•Benefits consumers by providing superior, uncompressed digital video
quality via a single cable6
•Is backward-compatible with DVI (Digital Visual Interface)
and user-friendly connector
•Supports two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
HDMI has the capacity to support:
•Existing high-definition video formats (720p, 1080i and 1080p @60Hz), as
well as standard definition formats such as NTSC or PAL
3.2 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.
3.3 About the Power Connect™ Feature
The Power Connect™ feature here means that only one unit in a system, the
transmitter or receiver, can 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 distances, heavy gauge cable should be used1
3.4 Defining EDID
.
The Extended Display Identification Data (EDID2
3.5 Recommendations for Best Performance
) is a data-structure provided by
a display, to describe its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the VM-114H4C to “know” what kind of
monitor is connected to the output. The EDID includes the manufacturer’s name,
the product type, the timing data supported by the display, the display size,
luminance data and (for digital displays only) the pixel mapping data.
To achieve the best performance:
•Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
•Avoid interference from neighboring electrical appliances and position your
VM-114H4C away from moisture, excessive sunlight and dust
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

, the VM-114H or the VM-114H2C).
5. (Optional) Connect a PC via RS-232 to the RS-232 port on the VM-114H4C
(see Section 5.3).
Figure 3: Connecting the VM-114H4C
5.2 Acquiring the EDID
Each input on the VM-114H4C has a factory default EDID loaded2
3.4
(see
Section ). This lets you connect the power before having to connect one of the
acceptors. The EDID for each input can be changed independently by uploading an
EDID binary file to each input via the RS-232 port using Kramer EDID Sender
software3

You can acquire the EDID1
•One output (the relevant output LED flashes)
from:
•The default EDID (all output LEDs flash)
•Up to four connected outputs using the Auto-mix Mode2
When pressing the EDID SELECT button briefly, the OUTPUT LEDs indicate the
source from which the EDID is acquired as follows:
(all output LEDs
light)
•OUTPUT 1 LED flashes—the EDID from OUTPUT 1 was the last acquired
•OUTPUT 2 LED flashes—the EDID from OUTPUT 2 was the last
acquired, and so on
•All OUTPUT LEDs flash—the Default EDID is stored in the non-volatile
memory
•All OUTPUT LEDs light—the Auto-Mix2EDID is stored in the non-
volatile memory
To acquire the EDID:
1. Connect the power.
2. Connect the output(s) from which you want to acquire the EDID.
3. Press and hold the EDID SELECT button to cycle through to the required
output.
4. Release the button when reaching the desired source3
5. Press EDID READ.
The EDID is acquired.
.
5.2.1 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 5.2.
1 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
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 If you set the machine to acquire the EDID from an output that is not connected, the default EDID will be acquired

KRAMER: SIMPLE CREATIVE TECHNOLOGY

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 5.2.
5.3 Connecting to the VM-114H4C via RS-232
You can connect to the VM-114H4C via an RS-232 connection using, for
example, a PC. Note that a null-modem adapter/connection is not required.
To connect to the VM-114H4C via RS-232:
•Connect the RS-232 9-pin D-sub rear panel port on the product unit via a
9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5
need to be connected) to the RS-232 9-pin D-sub port on your PC

5.4 RS-232 and 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 will
respond to control signals or transparently pass them through to another receiver or
transmitter. Three examples in Sections 5.4.2.1, 5.4.2.2 and 5.4.2.3 of various
configurations illustrate this functionality.
5.4.1 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
5.4.2 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.

KRAMER: SIMPLE CREATIVE TECHNOLOGY
Using the VM-114H4C
12
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.
5.4.2.1 IR Local Control and Pass-through Example One
The configuration is shown in Figure 5.
Figure 5: VM-114H4C IR Control and Pass-through Example One
A DVD player is connected to the TP-573 transmitter via an IR emitter.
An LCD display is connected to the TP-574 receiver via an IR emitter.
Both the TP-573 and the TP-574 are connected to the VM-114H4C via TP
cabling.
To control a device, point the appropriate remote control for the device at the
VM-114H4C IR sensor.

Figure 6: VM-114H4C IR Control and Pass-through Example Two
An IR sensor is connected to the TP-573 transmitter.
An LCD display is connected to the TP-574 receiver via an IR emitter.
Both the TP-573 and the TP-574 are connected to the VM-114H4C via TP
cabling.
To control the LCD display, point the LCD display remote control either at the
TP-573 IR sensor or at the VM-114H4C IR sensor. To control the VM-114H4C,
point the Kramer remote control at the VM-114H4C IR sensor.

Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial port, they
are usually configured together with each machine having an individual machine number. If the OVR bit is set, then all machine
numbers will accept (implement) the command, and the addressed machine will reply.
For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is configured as
MACHINE NUMBER = 1.

NOTES on the above table:
NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if the
instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the HEX code
01 85 88 83
was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8. If the user switched input 1 to output 7 via the front
panel keypad, then the switcher will send HEX codes:
41 81 87 83
to the PC.
When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by sending to
the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION bit is set high).
NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1, 2, 5 or 7, the
machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216, the reply to the request
to send the audio machine name would be (HEX codes):
7D 96 90 81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).
If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine will send its software version number.
Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number in front of the decimal
point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to the request to send the version
number would be (HEX codes):
7D 83 85 81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 5dec for 3rd byte).
If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine’s name is sent. For example, for the VS-
7588YC, the reply to the request to send the first suffix would be (HEX codes):
7D D9 C3 81 (i.e. 128dec+ ASCII for “Y”; 128dec+ ASCII for “C”).
NOTE 14 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system. For example, if
six 16X16 matrices are configured to make a 48X32 system (48 inputs, 32 outputs), the reply to the HEX code
3E 82 81 82 (ie. request the number of outputs)
would be HEX codes
7E 82 90 82
ie. 16 outputs
