BC-DGKat7a23 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.
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), and the Kramer BC-DGKat7a23 (CAT
7a 23 AWG) cables. These specially built cables significantly outperform regular
CAT 5/CAT 6 /CAT 7a cables.
1 EDID is Extended Display Identification Data (see Section 3 3 for a more detailed definition)
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

3.2 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 distances,
heavier gauge cable should be used1
!
.
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

5.2 Selecting an Active Input
To select an active input:
•Press the INPUT SELECTOR button until the required INPUT LED lights
5.3 Acquiring the EDID
Each input on the VM-114H has a factory default EDID loaded18(see Section ).
This lets you connect the power before having to connect one of the acceptors.
You can acquire the EDID2
•One output (the relevant output LED flashes)
from:
•The default EDID (all output LEDs flash)
•Up to four connected outputs using the Auto-mix Mode1
1 The VM-114H reads the EDID which is stored in the non-volatile memory
(all output LEDs light)
2 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

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.
5.3.1 Disabling/Enabling Deep Color Support

1st BYTE: Bit 7 – Defined as 0
D – “DESTINATION”: 0 - for sending information to the switchers (from the PC);
1 - for sending to the PC (from the switcher)
N5 N0 – “INSTRUCTION”
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits) Similarly, if a function is performed
via the machine’s keyboard, then these bits are set with the INSTRUCTION NO , which was performed The instruction codes are
defined according to the table below (INSTRUCTION NO is the value to be set for N5 N0)
2nd BYTE: Bit 7 – Defined as 1
I6 I0 – “INPUT”
When switching (ie instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched Similarly, if
switching is done via the machine’s front-panel, then these bits are set with the INPUT NUMBER which was switched For other
operations, these bits are defined according to the table
3rd BYTE: Bit 7 – Defined as 1
O6 O0 – “OUTPUT”
When switching (ie instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched Similarly, if
switching is done via the machine’s front-panel, then these bits are set with the OUTPUT NUMBER which was 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
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

62 DEFINE MACHINE 1 - number of inputs
2 - number of outputs 1 - for video 2 - for audio 14
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
