Kramer Electronics VS-5x4 user manual OUTPUT1 OUTPUT2 OUTPUT3 OUTPUT4 ALL, From Input OFF

Set your VS 5x4 switcher to Protocol 2000 by setting DIP 5 OFF.

Set your VS 5x4 switcher to the old protocol by setting DIP 5 ON.

Get full details of Protocol 2000 via the Technical Support section of our Web site (http://www.kramerelectronics.com).

Communication with the VIS-5X4 is defined using 2 bytes of information. Data transfer is at 9600 baud, with no parity, 8 data bits and one stop bit.

MSB		1st byte
N7	N6	N5	N4

LSB

N3 N2 N1 N0

MSB		2nd byte				LSB
N15	N14	N13	N12	N11	N10	N9	N8

Where:

N7 = 0 (continue bit).

N6N5N4N3 = 1000 (transmitted by the machine (to the PC), but not necessary when transmitting to the machine).

N2N1N0 is the binary value of the machine being addressed (or of the machine sending its data) minus one, e.g.. N2N1N0=000 to address machine #1 (the master);

N2N1N0=101 to address machine #6.

N15 = 1 (continue bit).

N14 = 0 for all communication from the PC.

N13N12 N11N10N9N8 = 10 0001 instructs a machine to send its present status. The machine returns 16 bytes. 4 pairs of bytes are sent for the status of the 4 outputs as defined by the table below, and 4 pairs for the gain settings of the 4 audio outputs as defined below.

N13N12 N11N10N9N8 = 10 0010 success code (the machine acknowledges the requested change in status).

N13N12 N11N10N9N8 = 10 0011 non-success code (the machine cannot perform the requested instruction).

NB:- Success/non-success codes, (according to the validity of the request), are returned from the machine which was instructed to change its status.

N13N12 N11N10N9N8 = 10 01GG set audio gain of output 1 N13N12 N11N10N9N8 = 10 10GG set audio gain of output 2 N13N12 N11N10N9N8 = 10 11GG set audio gain of output 3

N13N12 N11N10N9N8 = 11 00GG set audio gain of output 4 where GG is defined as follows: 00 = 0dB gain

01 = 2dB gain

10 = 4dB gain

11 = 6dB gain

The above gain setting codes are bi-directional, i.e., if the change was made on the machine, then the code is sent to the PC; and if the PC sends the code, then the change is made on the machine.

When N13 is low then N12N11N10N9N8 corresponds to the status (or the required change in status) of the machine, as described in the table below. These are bi-directional codes.

	OUTPUT1	OUTPUT2	OUTPUT3	OUTPUT4	ALL

FROM INPUT 2	5	6	7	8	22
FROM INPUT 3	9	10	11	12	23
