Kramer Protocol 2000

NOTE 5 - The reply to the "REQUEST SETTING" instruction is as NOTE 4 above, except that here the OUTPUT is assigned

with the value 0 – if there is no signal on the input, 1 – if the signal on the input is SD, or 2 – if the signal on the input is HD.

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 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter

associated with the instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an

input or output greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent while

the machine is being programmed via the front panel. Reception of this code by the switcher is not valid.

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 will send 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 will send 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 (ie. request the number of outputs)

would be HEX codes

ie. 16 outputs

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 25 – For units which detect the validity of the video inputs, Instruction 16 will be sent whenever the unit detects a

change in the state of an input (in real-time).

For example, if input 3 is detected as invalid, the unit will send the HEX codes

If input 7 is detected as valid, then the unit will send HEX codes

81.
