VP-4x1CS - Kramer Protocol 2000 29
NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are
returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are
as per the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is
breakaway setting, then the reply to the HEX code:
0B
80 80 85
would be HEX codes
4B
80 81 85
NOTE 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not
defined / no valid input is detected; or 1 if it is defined / valid input is detected.
NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as
1, 2, 5 or 7, the machine sends its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a
2216, the reply to the request to send the audio machine name would be (HEX codes):
7D
96 90 81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).
If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine sends its software version
number. Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number
in front of the decimal point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to
the request to send the version number would be (HEX codes):
7D
83 85 81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 5dec for 3rd byte).
If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine’s name is sent. For example, for
the VS-7588YC, the reply to the request to send the first suffix would be (HEX codes):
7D
D9 C3 81 (i.e. 128dec+ ASCII for “Y”; 128dec+ ASCII for “C”).
NOTE 14 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system.
For example, if six 16X16 matrices are configured to make a 48X32 system (48 inputs, 32 outputs), the reply to the HEX
code:
3E
82 81 82 (ie. request the number of outputs)
would be HEX codes:
7E
82 90 82
ie. 16 outputs
NOTE 15
– When the OVR bit (4th byte) is set, then the “video” commands have universal meaning. For example,
instruction 1 (SWITCH VIDEO) causes all units (including audio, data, etc.) to switch. Similarly, if a machine is in
“FOLLOW” mode, it performs any “video” instruction.
NOTE 16 -
The reply to the “REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 4 above, except that here the
OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.
11.1 Protocol 2000 Hex Codes
The following table lists the hex values to switch an input to the output for a single
VP-4x1CS device.
Video Audio
IN 1 10, 10, 10, 10
12, 10, 10, 10
IN 2 10, 12, 10, 10
12, 12, 10, 10
IN 3 10, 13, 10, 10
12, 13, 10, 10
IN 4 10, 14, 10, 10
12, 14, 10, 10
The following table lists the hex codes that increase or decrease audio input gain.
IN 1 IN 2 IN 3 IN 4
Increase
18 81 86 81 18 82 86 81 18 83 86 81 18 84 86 81
Decrease
18 81 87 81 18 82 87 81 18 83 87 81 18 84 87 81
The following table lists the hex codes that set the audio input gain.
