3.1 About Fast Switching
Older display devices required a longer time between the loss of one digital signal
and the introduction of another, as well as a physical disconnection of the
interconnecting cable in order to be able to detect and adjust to the new video
attributes and parameters. Normal switching, therefore, introduced a 5V signal
disconnection along with a delay in switching. Many newer display devices,
however, are now capable of “on-the-fly” switching.
Depending on the display device in use, the VS-42HDCP allows for fast switching
(minor reset and the connection kept alive) and extra fast switching (no reset and
the connection kept alive). Using the fast and extra fast switching modes allows for
fraction-of-a-second switching times when using high performance display devices
or when using a scaler on the video output.

11 Kramer Protocol 2000
The Kramer Protocol 2000 RS-232/RS-485 communication uses four bytes of
information as defined below. All the values in the table are decimal, unless
otherwise stated.
0 D N5 N4 N3 N2 N1 N0
2nd byte
MACHINE NUMBER
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 o per a ti ons, these bits are de fi ne d acc or ding 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 accept (implement) the command, and the addressed machine replies. 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 tabl e:
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 the switchers, it resets according to the present power-down settings.
NOTE 2 - These a r e bi-directional definitions. That is, if the switcher receives the code, it performs 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) switches input 5 to output 8. If the user switched input 1 to output 7
via the front panel keypad, then the switcher sends 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 3 - SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory, (i.e.
those used for Store a nd R ecal l ) .
NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are
returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are
as per the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is
breakaway setting, then the reply to the HEX code
0B 80 80 85
would be HEX codes
4B 80 81 85
NOTE 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not
defined / no valid input is detected; or 1 if it is defined / valid input is detected.

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 would be (HEX codes):
7D 96 90 81 (i.e. 128dec+ 22dec for 2nd byte, and 12 8d ec+ 16dec 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, th e re ply wo ul d be the dec im al value of the INPUT and OU T PU T - 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 f or 2n d byt e , 128 dec+ 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
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.
NOTE 16 - The reply to the “REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 4 above, except that here the
OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.
NOTE 19 - After this instruction is sent, the unit will respond to the ASCII command set defined by the OUTPUT byte.
The ASCII command to operate with the HEX command set must be sent in order to return to working with HEX codes.

12 Protocol 3000
By default, the VS-42HDCP is set to Protocol 3000 but is also compatible with
Kramer’s Protocol 2000 (see Section 11
Note that the VS-42HDCP needs to be set to Protocol 2000 in order to
use the IR remote control transmitter.
).
Section 9
The VS-42HDCP can be operated using serial commands from a PC, remote
controller or touch screen using the Kramer Protocol 3000. However, when used
in conjunction with the IR remote controller, these serial commands must also be
in Protocol 2000 format.
This section describes:
describes how to switch between Protocol 3000 and Protocol 2000.

12.1.3 Command Terms
Command
A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-').
Command and parameters must be separated by at least one space.
Parameters
A sequence of alphanumeric ASCII characters ('0'-'9','A'-'Z','a'-'z' and some special
characters for specific commands). Parameters are separated by commas.
Command SP [Param1 ,Param2 …] result CR LF
VS-42HDCP - Protocol 3000 27
Message string
Every command entered as part of a message string begins with a message
starting character and ends with a message closing character.
Note: A string can cont ai n more than one command. Commands are separated by
a pipe ( '|' ) character.
Message starting character
'#' – For host command/query
'~' – For device response
Device ID (Optional, for K-NET)
K-NET Device ID followed by '@'
Query sign
'?' follows some commands to define a query request.
Page 31
Message closing character
CR – For host messages; carri age return (ASCI I 13)
CRLF – For device m essages; carriage return (ASCII 13) + line-feed (ASCII 10)
Command chain separator character
When a message string contains more than one command, a pipe ( '|' ) character
separates each command.
Spaces between parameters or command terms are ignored.
12.1.4 Entering Commands
You can directly enter all commands using a terminal with ASCII communications
software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial
or Ethernet port on the Kramer device. To enter CR press the Enter key.
( LF is also sent but is ignored by command parser).
For commands sent from some non-Kramer controllers like Crestron, some
characters require special coding (such as, /X##). Refer to the controller manual.
12.1.5 Command Forms
Some commands have short name syntax in addition to long name syntax to allow
faster typing. The response is always in long syntax.
12.1.6 Chaining Commands
Multiple commands can be chained in the same string. Each command is
delimited by a pipe character (“|”). When chaining commands, enter the message
starting character and the message closing character only once, at the
beginning of the string and at the end.
Commands in the string do not execute until the closing character is entered.
A separate response is sent for every command in the chain.

12.3.1 Packet Protocol Structure
The packet protocol is designed to transfer large amounts of data, such as files, IR
commands, EDID data, and so on.
12.3.1.1 Using the Packet Protocol
To use the packet protocol:
1. Send a command: LDEDID
2. Receive Ready or ERR###
3. If Ready:
Send a packet
Receive OK on the last packet
Receive OK for the command
4. Packet structure:
Packet ID (1, 2, 3…) (2 bytes in length)
Length (data length + 2 for CRC) - (2 bytes in length)
Data (data length -2 bytes)
CRC - 2 bytes
01 02 03 04 05…
5. Response:
~NNNNSPOKCR LF
Where NNNN is the received packet ID in ASCII hex digits.
