Overview
The VP-81KSi routes any input to both outputs, using 15-pin HD female connectors
for the computer graphics video signals, a 3.5mm mini jack for the unbalanced stereo
audio Output 1 signal, and a detachable terminal block connector for the balanced
stereo audio Output 2 signal.
In particular, the VP-81KSi:
 Has a very high video bandwidth ensuring transparent WUXGA performance
 Features audio-follow-video (AFV) in which all operations relate to both the
video and the audio channels, or audio breakaway option, in which video and
audio channels are switched independently
 Features volume control
 Includes the Kramer innovative integrated sync processing Kr-isp™
technology, which lets you achieve a sharp, stable image even when the sync
level is too low, by restoring the sync signal waveform
 Up to eight units can be cascaded to provide a single “virtual” switcher with
up to 57 inputs
 Supports the SI-1VGA Remote Step-in Panel for remote inputs and remote
step-in control
You can control the VP-81KSi using the front panel buttons, or remotely via:
 RS-485 or RS-232 serial commands transmitted by a touch screen system, PC
or other serial controller
 Ethernet over a LAN using a Web browser
 The SI-1VGA Remote Step-in Panel
 The Kramer RC-IR3 Infrared Remote Control Transmitter or infrared remote
extension cable transmitter (optional)
 Remote, contact closure switches
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 that may adversely
influence signal quality and position your VP-81KSi away from moisture,
excessive sunlight and dust

Defining EDID
The Extended Display Identification Data (EDID1) is a data-structure, provided by
a display that describes its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the PC or laptop to “know” what kind of
monitor is connected to the output. The EDID includes the manufacturer’s name,
product type, timing data supported by the display, display size, luminance data
and (for digital displays only) pixel mapping data.

Figure 8 illustrates the factory default DIP-switch positions.
Figure 8: RS-485 DIP-switches
Table 3: RS-485 DIP-switch Settings
DIP-switch Number
Function
1, 2, 3
Machine number (see Table 4)
Default—All off (up), machine number 1
4
RS-485 Bus Termination
Default—Off (up)
DIP-switches 1, 2 and 3 determine the RS-485 machine number of the
VP-81KSi. When several VP-81KSi units are connected, the machine number
determines the unique identity of the VP-81KSi on the bus (see Table 4).
Note:
 When using a stand-alone VP-81KSi unit, set the machine number to 1
(factory default)
 When connecting more than one VP-81KSi, set the first machine (connected
via RS-232) to be machine number 1. The other VP-81KSi units must each be
set to a unique machine number between 2 and 16

DIP-switch 4 sets the RS-485 bus termination of the VP-81KSi. Only the first and
last physical units on the RS-485 bus must be terminated, all others must be
unterminated. Moving the DIP-switch up turns the termination off (default),
moving the switch down turns the termination on.
6.6.2 Connecting and Controlling Multiple VP-81KSi Devices
You can daisy-chain up to eight VP-81KSi devices with operation via RS-232
from a PC or serial controller.
To daisy-chain up to eight VP-81KSi devices:
1. Connect the RS-232 port1 on the first VP-81KSi device to the PC (see
Section 6.3).
2. Connect the RS-485 terminal block port on the first device to the RS-485 port
on the second device, and so on for all devices.
3. Set the DIP-switches (see Section 6.6.1) as follows:

The first device is machine number 1 and the following seven devices
are machine numbers 2 to 8

Terminate the first and last physical devices, that is, in this example
terminate machine numbers 1 and 8. Ensure that all other devices are
unterminated
6.7
Cascading Multiple VP-81KSi Devices
You can cascade up to eight VP-81KSi devices to build a single “virtual” switcher
with up to 57 inputs and one output as illustrated in Figure 9.
To cascade up to eight VP-81KSi devices:


The first device is machine number 1 (Master) and the following seven
devices are machine numbers 2 to 8

Terminate the first and last physical devices, that is, terminate machine
numbers 1 and 8. Ensure that all other devices are unterminated
Figure 9: Cascading up to Eight VP-81KSi Devices
Note: The video acceptor must be connected to the Master output. The outputs of
all other devices may be connected to any input on the subsequent device.
For operation of cascaded VP-81KSi devices, see Section 7.4.
6.8
Controlling a Remote RS-232 Device
Use the Kramer K-Config software1 to define macros sent from the RS-232-2 port
to remote RS-232 serial devices (for example, a projector). For instructions on
using the K-Config software, see the K-Config software guide.
A computer running the K-Config software can be connected to the VP-81KSi via
either the RS-232-1 serial or the Ethernet ports.
1 Download the latest version from http://www.kramerelectronics.com/support/?soft=k-config
15
Connecting the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher
You can configure RS-232-2 port command macros to send any data on one of the
two possible triggers:
 The “Device startup” trigger. This trigger is generated when one or more
signals are detected on any of the inputs and can be used for example, to
activate a projector connected to the output of the VP-81KSi
 The “Device inactivity” trigger. This trigger is generated when there is no
signal detected on any input during the inactivity timeout period (which is set
using the K-Config software to be between 0 and 180 minutes). This trigger
can be used for example, to deactivate a projector connected to the output of
the VP-81KSi
6.9 Connecting to the VP-81KSi via the Ethernet Port
You can connect the VP-81KSi via the Ethernet in the following ways:

Kramer Protocol
Section 17.1 describes how to switch between Protocol 3000 and Protocol1 2000.
By default, the VP-81KSi is set to protocol 3000 (see Section 17.2) but is also
compatible with Kramer’s Protocol 2000 (see Section 17.3).

Kramer Protocol
17.1 Switching Protocols
You can switch protocols either via the front panel buttons (see Section 17.1.1) or
the protocol commands (see Section 17.1.2).
17.1.1 Switching Protocols via the Front Panel Buttons
To switch from protocol 3000 to protocol 2000 via the:
 Front panel buttons, press the IN 1 and IN 2 button simultaneously
 Infrared remote control transmitter, press the TAKE button and then 13
To switch from protocol 2000 to protocol 3000 via the:
 Front panel buttons, press the IN 1 and IN 3 button simultaneously
 Infrared remote control transmitter, press the TAKE button and then 16
17.1.2 Switching Protocols via 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
®
1
The Windows -based Kramer control software operates with Protocol 2000.
If the VP-81KSi is set to Protocol 3000, it is automatically switched to
Protocol 2000.
17.2 Kramer Protocol 3000
This RS-232/RS-485 communication protocol lets you control the machine from
any standard terminal software (for example, Windows® HyperTerminal
Application).

17.2.2 Command Part Details
Command:
Sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-').
Command will separate from parameters with at least single space.
Parameters:
Sequence of Alfa-Numeric ASCII chars ('0'-'9','A'-'Z','a'-'z' and some special chars for specific commands), parameters will be separated
by commas.
Message string:
Every command must to be entered as part of message string that begin with message starting char and end with message closing char,
note that string can contain more then one command separated by pipe ("|") char.
Message starting char:
'#' for host command\query.
'~' for machine response.
Device address (Optional, for Knet):
Knet Device ID follow by '@' char.
Query sign = '?', will follow after some commands to define query request.
Message closing char =
Host messages - Carriage Return (ASCII 13), will be referred to by CR in this document.
Machine messages - Carriage Return (ASCII 13) + Line-Feed (ASCII 10), will be referred to by CRLF.
Spaces between parameters or command parts will be ignored.
Commands chain separator char:
When message string contains more than one command, commands will be separated by pipe ("|").
35
Kramer Protocol
Commands entering:
If terminal software used to connect over serial \ ethernet \ USB port, that possible to directly enter all commands characters ( CR will be
entered by Enter key, that key send also LF, but this char will be ignored by commands parser).
Sending commands from some controllers (like Crestron) require coding some characters in special form (like \X##). Anyway, there is a
way to enter all ASCII characters, so it is possible to send all commands also from controller.
(Similar way can use for URL \ Telnet support that maybe will be added in future).
Commands forms:
Some commands have short name syntax beside the full name to allow faster typing, response is always in long syntax.
Commands chaining:
It is possible to enter multiple commands in same string by '|' char (pipe).
In this case the message starting char and the message closing char will be entered just one time, in the string beginning and at the
end.
All the commands in string will not execute until the closing char will be entered.
Separate response will be sent for every command in the chain.
Input string max length:
64 characters.
Backward support:
Design note: transparent supporting for protocol 2000 will be implemented by switch protocol command from protocol 3000 to protocol
2000, in protocol 2000 there is already such a command to switch protocol to ASCII protocol (#56 : H38 H80 H83 H81).

17.3 Kramer Protocol 2000
This RS-232/RS-485 communication protocol (Version 0.5) 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.

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).
Bit 7 – Defined as 1.
2nd BYTE:
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.
Bit 7 – Defined as 1.
3rd BYTE:
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.

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 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 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
81
85
would be HEX codes
4B
80
NOTE 6 – If INPUT is set to 127 for these instructions, then, if the function is defined on this machine, it replies with OUTPUT=1. If
the function is not defined, then the machine replies with OUTPUT=0, or with an error (invalid instruction code).
If the INPUT is set to 126 for these instructions, then, if possible, the machine will return the current setting of this function, even for the
case that the function is not defined. For example, for a video switcher which always switches during the VIS of input #1, (and its VIS
setting cannot be programmed otherwise), the reply to the HEX code
0A
FE
80
81 (ie. request VIS setting, with INPUT set as 126dec)
81
81 (ie. VIS setting = 1, which is defined as VIS from input #1).
would be HEX codes
4A
FE
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 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 via
the front panel. Reception of this code by the switcher is not valid.
NOTE 10 – This code is reserved for internal use.
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
44
83
85
81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 5dec for 3rd byte).
KRAMER: SIMPLE CREATIVE TECHNOLOGY
Kramer Protocol
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 VS7588YC, 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)
90
82
would be HEX codes
7E
82
ie. 16 outputs
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 24 – Further information needed in instructions 21, 22, 25 and 26 is sent using instruction 42 – which is sent prior to the
instruction. For example, to request the audio gain value of right input # 9, send hex codes
2A
84
80
81
89
81
81.
and then send HEX codes
19
To set MIX mode, send hex codes
2A
81
84
81
and then send HEX codes
16
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.
