The unit can be controlled using the front panel buttons or:
Using an RC-IR3 infrared remote control transmitter (included)
Remotely, by RS-232 or RS-485 serial commands transmitted by a PC,
touch screen system, or other serial controller
Via the Ethernet
By default, the VS-44FO is controlled using the Kramer 3000 protocol (see Section
6.1.9 for details of how to switch to Protocol 2000 and Section 9 for the relevant
protocol commands).
3.1 Defining the SFP
An SFP is a small form-factor pluggable transceiver that is a compact, hotswappable, input/output transceiver used in data communication and
telecommunications networks. The SFP interfaces between communication
devices like switches, routers and fiber optic cables, and performs conversions
between optical and electrical signals.
The SFP transceiver is specified by the SFP Transceiver Multisource Agreement
(MSA), which was developed and is followed by different transceiver
manufacturers. SFP transceivers have a wide range of detachable interfaces to
multimode/single-mode fiber optics that allows users to select the appropriate
transceiver according to the required optical range for the network. The VS-44FO
supports use of non-MSA (SFP Transceiver Multisource Agreement) video
modules and MSA communication modules.
3.2 Defining the VS-44FO 4x4 3G HD-SDI Fiber Optic Matrix
The optical transceiver modules are engineered for exceptional performance in the
presence of SDI pathological patterns. The transceivers feature best-in-class
optical receiver sensitivity for SMPTE 259M, SMPTE 344M, SMPTE 292M and
SMPTE 424M serial rates, to provide superior optical link budget and robustness.

VS-44FO - Kramer Protocol 3000
9 Kramer Protocol 3000
The VS-44FO can be operated using serial commands from a PC, remote
controller, or touch screen. The unit communicates using the default Kramer
Protocol 3000 but can also use Kramer Protocol 2000.
This section describes:
How to switch between Protocol 3000 and Protocol 2000 (see Section 9.1)
Kramer Protocol 3000 syntax (see Section 9.2)
Kramer Protocol 3000 commands (see Section 9.3)
9.1 Switching Protocols
Protocols can be switched either from the front panel buttons or by transmitting
protocol commands.
To switch protocols using the front panel buttons:
To choose Protocol 2000, press OUT 1 and OUT 2 at the same time
To choose the Protocol 3000, press OUT 1 and OUT 3 at the same time
To switch protocols using protocol commands:
To switch from Protocol 3000 to Protocol 2000, send the following command:
#P2000<CR>
To switch from Protocol 2000 to Protocol 3000, send the following command:
0x38, 0x80, 0x83, 0x81
Note: If you are using Kramer’s Windows®-based control software it operates only
with Protocol 2000. If the VS-44FO is set to Protocol 3000, it automatically
switches to Protocol 2000.

9.2 Kramer Protocol 3000 Syntax
Protocol 3000 communicates at a data rate of 115200 baud, no parity, 8 data bits
and 1 stop bit.
9.2.1 Host Message Format
9.2.2 Simple Command
Command string with only one command without addressing:
9.2.3 Command String
Formal syntax with commands concatenation and addressing:
9.2.4 Device Message Format
9.2.5 Device Long Response
Echoing command:
CR = Carriage return (ASCII 13 = 0x0D)
LF = Line feed (ASCII 10 = 0x0A)
SP = Space (ASCII 32 = 0x20)
30
VS-44FO - Kramer Protocol 3000
9.2.6 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 alphameric ASCII characters ('0'-'9','A'-'Z','a'-'z' and some special
characters for specific commands). Parameters are separated by commas.
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 contain more than one command. Commands are separated by
a pipe ( '|' ) character.
Message starting character
'#' – For host command/query
'~' – For machine response
Device address (Optional, for K-NET)
K-NET Device ID followed by '@'
Query sign
'?' follows some commands to define a query request.
Message closing character
CR – For host messages; carriage return (ASCII 13)
CRLF – For machine messages; carriage return (ASCII 13) + line-feed (ASCII 10)
Command chain separator character
When a message string contains more then one command, a pipe ( '|' ) character
separates each command.
Spaces between parameters or command terms are ignored.
VS-44FO - Kramer Protocol 3000
31
9.2.7 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,
Ethernet, or USB 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.
9.2.8 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.
9.2.9 Command Chaining
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.
9.2.10 Maximum String Length
64 characters
9.2.11 Backward Support
Protocol 2000 is transparently supported by Protocol 3000. You can switch
between protocols using a switch protocol command from either platform.

11 Kramer Protocol 2000
The VS-44FO is compatible with Kramer’s Protocol 2000, version 0.50. This
RS-232/RS-485 communication protocol uses four bytes of information as defined
below. The default data rate is 9600 baud, with no parity, 8 data bits, and 1 stop
bit.
1st byte
2nd byte
3rd byte
4th byte
1st BYTE: Bit 7 – Defined as 0. D – “DESTINATION”:
0 - for sending information to the switchers (from the PC);
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a
function is performed using 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 (i.e. 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 using 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 (i.e. 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 using 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 using 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 using the serial port, always set M4…M0 = 1, and make sure that the machine
itself is configured as MACHINE NUMBER = 1.
Note: All values in the table are decimal, unless otherwise stated.
1 - for sending to the PC (from the switcher).

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 the switchers, it will reset according to the present power-down settings.
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 using 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 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 and Recall).
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.
38
VS-44FO - Kramer Protocol 2000
NOTE 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or
if a parameter associated with the instruction is out of range (e.g. trying to save to a setup greater
than the highest one, or trying to switch an input or output greater than the highest one defined). This
code is also returned to the PC if an RS-232 instruction is sent while the machine is being
programmed using the front panel. Reception of this code by the switcher is not valid.
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 machine name
would be (HEX codes):
7D 96 90 81 (i.e. 128
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. 128
If the OUTPUT is set as 1, then the ASCII coding of the lettering followi ng 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. 128
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 (i.e. request the number of outputs)
would be HEX codes
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) will cause all units (including data, etc.) to switch.
Similarly, if a machine is in “FOLLOW” mode, it will perform 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.
NOTE 25 – For units which detect the validity of the video inputs, Instruction 16 will be sent whenever
the unit detects a change in the state of an input (in real-time).
For example, if input 3 is detected as invalid, the unit will send the HEX codes
10 83 84 81
If input 7 is detected as valid, then the unit will send HEX codes
10 87 85 81.
