3 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
sync
1
 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” button
2
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

In addition, you can choose to connect the following options:
 A PC (when using the Kramer Control software, for example) or other
RS-232 (refer to section 5.1) or RS-485 controller (refer to section 5.2).
 A remote dry contact switch (refer to section 5.4)
5.1 Controlling via RS-232 (for example, using a PC)
To connect a PC to the VS-402xl/VS-602xl unit, using the Null-modem
adapter provided with the machine (recommended):
 Connect the RS-232 DB9 rear panel port on the VS-402xl/VS-602xl unit
to the Null-modem adapter and connect the Null-modem adapter with a 9 wire
flat cable to the RS-232 DB9 port on your PC
To connect a PC to the VS-402xl/VS-602xl unit, 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-402xl/VS-602xl unit, as Figure 3 illustrates (depending on
whether the PC has a 9-pin or 25-pin connector)
Figure 3: Connecting a PC without using a Null-modem Adapter
You can connect up to 8 VS-402xl/VS-602xl units to the PC via the
Null-modem adapter and the RS-232 port, and the RS-485 ports, as Figure 9
illustrates.
5.2 Controlling via RS-485
You can control a VS-402xl/VS-602xl unit via an RS-485 controller, for
example, a PC (equipped with an RS-485 interface) or a Master
Programmable Remote Control system such as the Kramer VS-3000.
