Your VS-626 (VS-828) Video Audio Matrix Switcher
The VS-626 (VS-828) includes:
A bandwidth of 100MHz that ensures transparency even in the most critical
applications
6 (8) input and 6 (8) output button selectors
8 preset memory locations for quick access to common configurations1
Audio-follow-video or audio breakaway option (to switch audio
independently from video)
A unique vertical and horizontal sync-pulse solution
Glitch-free transitions, which are produced when sources share a
common reference sync, as switching occurs during the vertical interval2
An external Sync/Genlock input that may be programmed to switch
according to the timing of either this input or of source number 1
Control the VS-626 (VS-828) 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
The Kramer RC-IR1 Infra-Red Remote Control Transmitter3
The VS-626 (VS-828) is dependable, rugged and fits into two vertical spaces
(2U) of a standard 19" rack. 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 and position your
Kramer VS-626 (VS-828) away from moisture, excessive sunlight and dust

Your VS-626 (VS-828) Video Audio Matrix Switcher
Figure 1 illustrates the VS-626 and Figure 2 illustrates the VS-828. Table 1 and
Table 2 define the front and rear panels of the VS-626 (VS-828), respectively.
1 On the VS-626, 8 preset memory locations are available via RS-232
2 When one video signal replaces another video signal, the switching process causes a random interruption in the first video
signal (in the middle of a frame) and a random entrance into the second video signal (also in the middle of a frame). The
result is a visible jump in the edited tape. This deteriorates when the tape is copied, and the disturbance on playback is more
serious. Avoid this by switching at a very specific point during the vertical interval, allowing smooth replacement of a whole
frame by a second whole frame as long as the video sources are Genlocked to each other

SELF ADDRESS Dipswitches
The SELF ADDRESS dipswitch determines the position of a VS-626
(VS-828) unit in the sequence, specifying which VS-626 (VS-828) unit is
being controlled, when several VS-626 (VS-828) units are controlled by a PC
or serial controller. Set the SELF ADDRESS on a VS-626 (VS-828) unit via
dipswitches 1, 2, and 3, according to Table 4.

Connecting a VS-626 (VS-828) Video / Audio Matrix Switcher
Up to 8 Matrix Switchers may be cascaded for control via a single port by
configuring one Matrix Switcher as a Master (SELF ADDRESS = 1)1, while
all the others are assigned as Slave Matrix Switchers or an ID other than "1".
5.1.2
Setting Connection Dipswitches
When connecting a PC via the RS-232, set dipswitch # 8 to ON. When
connecting a PC via the RS-485, set dipswitch # 8 to OFF.
Dipswitch # 5 enables or disables Reply from the Matrix Switcher to the PC.
In some applications, it may be desirable for some machines not to reply to
instructions received on the RS-232 and RS-485 ports. If so, set the Reply
dipswitch to OFF.
In the case of interconnection between more than two RS-485 receiverstransmitters (including PC), the termination resistor must be disconnected on
all the devices, except for the first (usually the PC) and last units on the
communication line. Dipswitch # 4 connects or disconnects the termination
resistor.
1 The default is for Master (SELF ADDRESS=1) and this is the recommended setting for a single machine

5.2 Controlling via RS-232 (for example, using a PC)
To connect a PC to the VS-626 (VS-828) unit1, using the Null-modem
adapter provided with the machine (recommended):
Connect the RS-232 DB9 rear panel port on the VS-626 (VS-828) unit to
the Null-modem adapter and connect the Null-modem adapter with a 9
wire flat cable2 to the RS-232 DB9 port on your PC
To connect a PC to the VS-626 (VS-828) unit1, without using a Null-modem
adapter:
Connect the RS-232 DB9 port on your PC to the RS-232 DB9 rear panel
port on the VS-626 (VS-828) unit, as Figure 5 illustrates2 (depending on
whether the PC has a 9-pin or 25-pin connector)
Figure 5: Connecting a PC without using a Null-modem Adapter
1 When connecting a single VS-626 (VS-828) unit via RS-232, set the SELF ADDRESS dipswitches to Machine # 1,
according to Table 4

5.3 Controlling via RS-232 and RS-485
You can control up to eight single VS-626 (VS-828) units with control from a
PC via RS-232 (see section 5.2) and RS-485 as illustrated in Figure 6.
To control via RS-232 and RS-485, do as follows:
1. Connect the video sources and acceptors, the appropriate audio sources
and acceptors, and the power cord to each VS-626 (VS-828) unit.
2. On each VS-626 (VS-828) unit, set the SELF ADDRESS dipswitches, as
required1 (see Table 4).
3. Connect the RS-232 port on the first unit to the PC2.
4. Interconnect the RS-485 ports on all the VS-626 (VS-828) units: from
the RS-485 port on the first VS-626 (VS-828) unit, to the RS-485 port
on the second VS-626 (VS-828) unit, and so on – up to the RS-485 port
on the last unit.
5. Terminate the RS-485 line as described in section 5.1.2.
Self Address = 1 (Master)
Self Address = 3

5.4 RGB/YUV Switching with RS-232 (PC Control)
Figure 7 describes a typical component video/RGB setup where every video
signal is composed of three sub signals (components), which should be
switched together (also valid for YUV components).
For RS-232 control of the component matrix switcher, an additional piece of
equipment would be required. Since RS-232 can only be used for control
between 2 pieces of equipment (e.g. a PC and a switcher), we need a method
of “distributing” the RS-232 to all 3 machines. The Kramer VP-14 “RS-232
Port Extender” is designed for this purpose.
Perform the following steps (as necessary):
1. Connect the RGB sources to the VIDEO INPUTS connectors of the
Matrix Switchers, connecting the “R” components to first Matrix
Switcher, “G” to the second, and “B” to the third. Make sure that each
component of a video source is connected to the same input number on
all three switchers.
2. Similarly, connect the RGB acceptors to the VIDEO OUTPUTS
connectors of the three Matrix Switchers.
3. If the video sources are synchronized, and vertical interval switching is
desired, connect sync sources to all 3 machines, and select to work with
“Ext. Sync” (selector switch pressed in).
4. Assign all 3 machines as Self Address # 1 (see Table 4).
5. Set dipswitch # 5 (Reply) of the first machine to ON. Set to OFF for the
other machines.
6. Set dipswitch # 8 of all the machines to ON (RS-232 communication
between switchers and external controller).
7. Connect the serial port of the PC to a port on the VP-14, and connect
each switcher to a VP-14 port. Configure the dipswitches of the VP-14
for the 4 ports, which were connected.
8. Operate the Matrix Switchers, PC, VP-14, RGB sources and RGB
acceptors.
9. The inputs can now be switched to the outputs. This is done via the front
panel switches of the first switcher, and/or via the PC.

1st BYTE: Bit 7 – Defined as 0.
D – “ DESTINATION”
This bit is always "low", when sending from the PC to the Matrix Switchers, and "high" for information
sent to the PC.
N5…N0 – “ INSTRUCTION”.
The function that is to be performed by the Matrix 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.
Bits 4 – 6 - Defined as 0.
I3… I0 – “ INPUT”.
When switching via RS-232 for RS- 485 (for instruction codes 1 and 2), these bits set the input that 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 disconnect,
set as 0. For other operations, these bits are defined according to the table.
3rd BYTE:
Bit 7 – Defined as 1.
Bits 4 – 6 Defined as 0.
O3…O0 – “ OUTPUT”.
When switching via RS-232 or RS-485 (for instruction codes 1 and 2), the output to switch is set by these bits. 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.
Bits 3 – 6 Defined as 0.
M2… M0 – “ Machine Number”.
Machine Number = (DIP – Switch Code) + 1.

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 performs the instruction, and if the instruction
is performed (due to a keystroke on the front panel), then these codes are sent. For example:
0000 0001
1000 0101
1000 1000
0011
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:
0100 0001
1000 0001
1000 0111
1000 0011
to the PC.

KRAMER: SIMPLE CREATIVE TECHNOLOGY
Communication Protocol
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 sent (except for the first byte, where the DESTINATION bit is set "high").
NOTE 3 - 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
0000 1011
0100 1100
1000 0001
1000 0001
Would be
1000 0000
1000 0001
1000 0101
1000 0101
NOTE 4-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 5-An error code is returned to the PC if an invalid code was sent to the switcher (e.g. trying to save to a setup greater than 8, 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 6–This code is reserved for internal use.
NOTE 7-SETUP # 0 is the present setting. SETUP # 1 to SETU P# 8 are the settings saved in the switcher'
s memory, (i.e. those used
for Store and Recall).
NOTE 8-Under normal conditions, the machine'
s present status is saved each time a change is made. The "power-down" save (autosave) may be disabled using this code. Note that whenever the machine is turned on, auto-save function is set.
NOTE 9–This is identical to instruction 3 (machine uses instruction 3, when sending to PC).
NOTE 10–This is identical to instruction 4 (machine uses instruction 4, when sending to PC).
NOTE 11-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, the reply to the request to send machine name (for machine
number 001) would be:
0111 1101
1000 1000 (i.e. 128 + 8)
1000 1000 (i.e. 128 + 8)
1000 0001
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 would be:
0111 1101
1000 0011 (i.e. 128 + 3)
1000 0101 (i.e. 128 + 5)
1000 0001
