Overview

KRAMER ELECTRONICS, LTD.

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

 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

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

5 Connecting a Vertical Interval Video-Audio Matrix Switcher

To connect the VS-402xl/VS-602xl, connect the following

to the rear panel:

1. The composite video sources and acceptors, as well as the appropriate

audio sources and acceptors.

2. The power cord.

2 The factory default

3 Insert a screwdriver into the small hole and carefully rotate it, trimming the OUTPUT level or EQ level

4 Switch OFF the power on each device before connecting it to your VS-402xl/VS-602xl Switcher. After connecting your

VS-402xl/VS-602xl Switcher, switch on its power and then switch on the power on each device. Switching on the

VS-402xl/VS-602xl Switcher, recalls the last status prior to powering down

KRAMER ELECTRONICS, LTD.

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.

Connecting a Vertical Interval Video-Audio Matrix Switcher

To connect a VS-3000 to a VS-402xl/VS-602xl unit

(see Figure 4):

1. Connect the RS-485 terminal block port on the VS-3000 to the RS-485

port on the VS-402xl/VS-602xl unit, as follows:

 Connect the “ A” (+) PIN on the RS-485 rear panel port of the VS-3000 to

the “ A” (+) PIN on the RS-485 rear panel port of the VS-402xl/VS-602xl unit

 Connect the “ B” (-) PIN on the RS-485 rear panel port of the VS-3000 to

the “ B” (-) PIN on the RS-485 rear panel port of the VS-402xl/VS-602xl unit

 If shielded twisted pair cable is used, the shield may be connected to the

“ G” (Ground) PIN on one of the units (for example, on the VS-3000)

2. Set the VS-402xl/VS-602xl unit as MACHINE # 1, according to Table 5

3. Set the SETUP dipswitches on the VS-402xl/VS-602xl unit, as follows:

 Set Dip 4 ON, Dip 6 ON and Dip 7 ON

 Set Dip 5, and Dip 8 OFF

Figure 4: Controlling via RS-485 (for example, using a VS-3000)

5.3 Setting the Dipswitches

Figure 5 illustrates the factory default SETUP dipswitches:
