Kramer Electronics VS-5x4 user manual RS-232 Control, Audio Level Control, Unit

￿￿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:

UNIT 1 (Master)	1	2	3	4	5	6	7	8
	OFF	OFF	OFF	ON	ON	ON	ON	ON
UNIT 2	ON	OFF	OFF	OFF	OFF	OFF	OFF	OFF
UNIT 3	OFF	ON	OFF	OFF	OFF	OFF	OFF	OFF
UNIT 4	ON	ON	OFF	OFF	OFF	OFF	OFF	OFF
UNIT 5	OFF	OFF	ON	OFF	OFF	OFF	OFF	OFF
UNIT 6	ON	OFF	ON	OFF	OFF	OFF	OFF	OFF
UNIT 7	OFF	ON	ON	OFF	OFF	OFF	OFF	OFF
UNIT 8	ON	ON	ON	OFF	OFF	OFF	OFF	OFF

12.RS-232 CONTROL

1.To control the VS-5x4using 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-5x4via an IBM compatible PC. Please read the readme.txt file before installation.

3.The Windows ™ based program, the K-SWITCHsoftware, 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-5x4may 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.
