VM-114H - Overview

3 Overview

The high-quality VM-114H 2x Input 1:4 HDMI DA 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 identical HDMI outputs.

In particular, the VM-114H features:

 A maximum data rate of 6.75 Gbps (2.25Gbps per graphic channel) (HDMI),

4.95Gbps (1.65Gbps per graphic channel) (DGKat)

 Reading and storing, 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

 I-EDIDPro™ Kramer Intelligent EDID Processing™ an intelligent EDID

handling & processing algorithm ensures Plug and Play operation for HDMI
systems

 3D Pass-through, Deep Color (on the HDMI input), x.v.Color™ and

uncompressed audio channels (Dolby TrueHD, DTS-HD)

 HDCP compliance
 LEDs indicating the selected input and active output
 IR remote control
 12V DC supply and is housed in a Kramer desktop enclosure

The VM-114H supports ranges 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-114H - Overview

5

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 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).

Warning: Using an incorrectly wired TP cable will cause permanent
damage to the device!

5 Using the VM-114H 2x Input 1:4 HDMI DA

This section describes how to acquire the EDID (see Section 5.1) and how to
connect via RS-232 (see Section 5.3).

5.1 Selecting an Active Input

To select an active input:

 Press the INPUT SELECTOR button until the required INPUT LED lights

5.2 Acquiring the EDID

Each input on the VM-114H has a factory default EDID loaded in non-volatile
memory (see Section 8). This lets you connect the power before having to connect
one of the acceptors.

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 device enters the EDID programming mode. 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).

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.

5.2.1 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.

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-114H via RS-232

You can connect to the VM-114H 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-114H 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

VM-114H - Protocol 2000

9 Protocol 2000

This RS-232/RS-485 communication protocol uses four bytes of information as
defined below.

For RS-232, a null-modem connection between the machine and controller is
used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit.

Note: Compatibility with Kramer’s Protocol 2000 does not mean that a machine
uses all of the commands below. Each machine uses a sub-set of Protocol 2000,
according to its needs.

1st Byte: Bit 7 – Defined as 0

D – DESTINATION:

0 – Sends information to the switchers (from the PC)
1 – Sends information to the PC (from the switcher)

N5…N0 – INSTRUCTION
The 6-bit INSTRUCTION defines the function performed by the switcher(s). If a function is performed using the
machine’s keyboard, these bits are set with the INSTRUCTION NO. performed. The instruction codes are defined
according to the table below (INSTRUCTION NO. is the value set in N5…N0).

2nd Byte: Bit 7 – Defined as 1
I6…I0 – INPUT
When switching (i.e. instruction codes 1 and 2), the 7-bit INPUT is set as the input number to be switched. If switching is
done using the machine’s front panel, these bits are set with the INPUT NUMBER switched. For other operations, these
bits are defined according to the table.

3rd Byte: Bit 7 – Defined as 1
O6…O0 – OUTPUT
When switching (i.e. instruction codes 1 and 2), the 7-bit OUTPUT is set as the output number to be switched. If
switching is done using the machine’s front panel, these bits are set with the OUTPUT NUMBER switched. For other
operations, these bits are defined according to the table.

4th Byte: Bit 7 – Defined as 1
Bit 5 – Don’t care
OVR – Machine number override
M4…M0 – MACHINE NUMBER
This byte is used to address machines in a system by their machine numbers. When several machines are controlled
from a single serial port, they are usually configured together and each machine has an individual machine number. If
the OVR bit is set, then all machine numbers accept (implement) the command and the addressed machine replies.

VM-114H - Protocol 2000

When a single machine is controlled over the serial port, always set M4…M0 to 1, and make sure that the machine itself
is configured as MACHINE NUMBER = 1.

NOTES on the above table:
NOTE 1 – When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is

sent to a switcher, it resets according to the present power-down settings.
NOTE 2 – These are bi-directional definitions. If the switcher receives the code, it performs the instruction. If the

instruction is performed (due to a keystroke operation on the front panel), then these codes are sent.
For example, if the PC sends HEX code:
01 85 88 83
then the switcher (machine 3) switches input 5 to output 8.
If the user switches input 1 to output 7 using the front panel buttons, the switcher sends HEX code:
41 81 87 83
to the PC.
When the PC sends one of the commands in this group to the switcher, if the instruction is valid, the switcher replies by
sending the same four bytes to the PC that it received (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 sends 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 is HEX code:
7D 96 90 81 (i.e. 128

dec

+ 22

dec

for 2nd byte, and 128

dec

+ 16

dec

for 3rd byte).

If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine sends 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 code:
7D 83 85 81 (i.e. 128

dec

+ 3

dec

for 2nd byte, 128

dec

+ 5

dec

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 code:
7D D9 C3 81 (i.e. 128

dec

+ ASCII for “Y”; 128

dec

+ ASCII for “C”).

NOTE 14 – The number of inputs and outputs refers to the specific machine 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 (i.e. request the number of outputs)
would be HEX code:
7E 82 90 82 (i.e. 16 outputs).

NOTE 15 – When the OVR bit (4th byte) is set, then the video commands have universal meaning.
For example, instruction 1 (SWITCH VIDEO) causes all units (including audio, data, etc.) to switch. Similarly, if a
machine is in FOLLOW mode, it performs any video instruction.
