Overview
The Kramer VS-602xl (a 6x2 switcher) and VS-402xl (a 4x2 switcher) are
high performance vertical interval matrix switchers for composite video and
stereo balanced audio signals. Both are true matrix switchers - enabling the
user to route any input to any or all outputs simultaneously.
In addition, both the VS-602xl and the VS-402xl:
Have video bandwidth that exceeds 300 MHz, ensuring that they remain
transparent even in the most critical applications
Include audio-follow-video or audio breakaway option
Produce glitch-free transitions, when sources share a common reference
sync1
Include 2 sets of INPUT SELECTOR buttons (one set for each output)
and 5 front panel control buttons
Include 2 duplicate outputs per set of INPUT SELECTOR buttons (4
outputs in total)
Include a “Take” button2 for precise switch control and a “Lock” button
to prevent tampering with the front panel
Are controllable via the front panel buttons, or remotely by RS-485 or
RS-232 serial commands transmitted by a touch screen system, PC, or other
serial controller
Achieving the best performance means:
Connecting 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)
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality
Positioning your Kramer VS-402xl or VS-602xl in a location free from
moisture and away from excessive sunlight and dust

7.1 Choosing the Audio-Follow-Video or Breakaway Option
You can switch stereo audio signals in one of 2 ways, either:
Audio-follow-video (AFV), in which all operations relate to both the
video and the audio channels; or
Breakaway, in which video and audio channels switch independently
7.1.1
Setting the Audio-Follow-Video Option
To set the Audio-follow-video (AFV) option, when the AUDIO and VIDEO
configurations are the same:
Press the AFV button
The AFV1 button illuminates. The audio will follow the video
To set the Audio-follow-video (AFV) option, when the AUDIO configuration
differs from the VIDEO configuration:
Press the AFV button
The TAKE and the AUDIO buttons flash2, even when working in the AT
ONCE mode3
Press the TAKE button to confirm the modification. The audio will
follow the video
7.1.2
Setting the Breakaway Option
To set the Breakaway option:
8
1.
Press either the AUDIO (for audio control only) or the VIDEO (for video
control only) button.
2.
If the AUDIO button illuminates, switching operations relate to Audio.
3.
If the VIDEO button illuminates, switching operations relate to Video.
Technical Specifications
Table 6 includes the technical specifications:
1 When cascading units in an input expansion configuration or RGB(H) mode, as section 6.1 describes, pressing the front
panel AFV button on one interconnected VS-402xl/VS-602xl unit also illuminates the AFV button on the other
VS-402xl/VS-602xl units. However, pressing the VIDEO or AUDIO button on an interconnected VS-402xl/VS-602xl unit
does not illuminate the corresponding VIDEO or AUDIO buttons on the other VS-402xl/VS-602xl units.

Communication Protocol
10 Communication Protocol
This protocol, which enables RS-232 communication between the
VS-402xl/VS-602xl and the PC, uses 4 bytes of information, and data is at
9600 baud, 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).
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.

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:
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 to SETUP # 15 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
21
Communication Protocol
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
4B
80
81
85
NOTE 5 – For the OUTPUT byte set as 6, the VIS source is the input selected using the OUTPUT byte. Similarly, for the
OUTPUT byte set as 7, the VIS source is the output selected using the OUTPUT byte. Note also, that on some machines the
sync source is not software selectable, but is selected using switches, jumpers, etc!
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), or will not reply.
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
4A
FE
80
81 (ie. request VIS setting, with INPUT set as 126dec)
would be
4A
FE
81
81 (ie. VIS setting = 1, which is defined as VIS from input #1).
NOTE 7 – Setting OUTPUT to 0 will return the VIS source setting as defined in instruction #7. Setting to 1 will return the
input # or output # of the sync source (for the case where the VIS source is set as 6 or as 7 in instruction #7). Setting to 2
returns the vertical sync frequency (0 for no input sync, 50 for PAL, 60 for NTSC, 127 for error).
NOTE 8 - The reply to the "REQUEST WHETHER SETUP IS DEFINED" is as in TYPE 3 above, except that here the
OUTPUT is assigned with the value 0 if the setup is not defined; or 1 if it is defined.
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 15, 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 11 – For machines where the video and / or audio gain is programmable. The value of the gain is represented in twos
complement form to allow for negative values (attenuation).
NOTE 12 - Under normal conditions, the machine'
s present status is saved each time a change is made. The "power-down"
save (auto-save) may be disabled using this code. Note that whenever the machine is turned on, the auto-save function is set.
NOTE 13 - This is a request to identify the switcher/s in the system. If the INPUT is set as 1 or 2, 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).
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
7E
82
90
82
ie. 16 outputs
NOTE 16 - The reply to the “ REQUEST WHETHER PANEL IS LOCKED” is as 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.
