VP-1608 - Kramer Protocol 2000

NOTE 12

- Under normal conditions, the machine's present status is saved each time a change is made. The "power-

down" save (auto-save) may be disabled using this code. Note that whenever the machine is turned on, the auto-save

function is set.

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):

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):

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):

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

82 (i.e. request the number of outputs)

would be HEX codes

i.e. 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.

NOTE 19

– When data (i.e. the INPUT and/or OUTPUT bytes) of more than 7 bits is required, this instruction is sent

before sending the instruction needing the additional bits. The data in this instruction then becomes the Most Significant

Bits of that next instruction. For example, to set the audio gain (instruction 22) of output 3 to 681dec (2A9hex), you

would first send HEX codes

and then send HEX codes

To set the audio gain of output 6 to 10013dec (271Dhex), first send HEX codes

followed by HEX codes

NOTE 21

– Instruction 59 and instruction 60 load data for sending to the crosspoint switcher (or for storing in a SETUP),

i.e. the data is “lined-up” to be executed later. Instruction 58 executes the loaded data.

NOTE 22

– If the INPUT byte is set as 127dec, then the data stored in a SETUP is loaded. The SETUP # is in the

OUTPUT byte.

NOTE 23

– Further information needed in instructions 21, 22, 25 and 26, is sent using instruction 42 – which is sent

prior to the instruction. For example, to request the audio gain value of right input # 9, send hex codes

and then send HEX codes
