If several machines are to be used “in parallel” to switch together, e.g.. when using 4 machines
together to make a 5X4 RGBS switcher, then all the parallel machines should be set up to have the
same slave number and switch 4 should be ON for the machine which switches the syncs. A 9-pin flat
cable should be used to interconnect the machines via their RS-232 ports.
The dip-switch settings are as follows:
1 2 3 4 5 6 7 8
UNIT 1 (Master) OFF OFF OFF ON ON ON ON ON
UNIT 2

UNIT 3

UNIT 6

UNIT 8

12. RS-232 CONTROL
1. To control the VS-5x4 using RS-232, connect the "9 pin to 9 pin adapter" (provided with the
machine) to the 9 pin serial port of the PC. Use a flat cable to connect from the 9 pin of the VS-
5x4 to the 9 pin of the null modem adapter. (The adapter is a null-modem plug and 9-pin to 9-
pin converter - see diagram below).
2. The DOS based PC program may be downloaded from the Internet at the Kramer Website /
Technical support section. The website address is: www.kramerelectronics.com .The program
allows control and monitoring of the VS-5x4 via an IBM compatible PC. Please read the
readme.txt file before installation.
3. The Windows ™ based program, the K-SWITCH software, which comes with the machine, is
fully described in the software manual. Please follow the instructions carefully. If needed, you
may download the latest version of the program from the site above.
4. The protocol used for contro1ling the VS-5x4 may be found below.
5. If several machines are used (in a master / slave setup, or if they are connected in parallel to
switch together), then the machines should be daisy-chained via their 9 pin interface sockets
using a flat-cable.
13. AUDIO LEVEL CONTROL
To select the audio gain for one of the outputs, simultaneously press this output key together with the
“ALL” key. Then, while both these keys are being held down, press the input key according to the
required gain defined as:
1- 0 dB gain
2- 2 dB gain
3- 4 dB gain
4- 6 dB gain
14. PROTOCOLS USED FOR RS-232 COMMUNICATION
The factory default of the VS 5x4 switcher is set for Protocol 2000. There are 2 built-in
communication protocols. Choose to operate your VS 5x4 switcher using:
Protocol 2000 (via the K-ontrol or K-Router software) to control different switchers or
switchers/matrix groups from one screen.
The old protocol (via the K-switch software) for simple and fast control of a single switcher or
several interconnected machines.
When not using the K-switch, K-ontrol or K-Router software, it is recommended to operate using
Protocol 2000, which provides more control over the switchers, and is more advanced than the old
protocol supported by the K-switch software.
