KRAMER: SIMPLE CREATIVE TECHNOLOGY

Kramer Protocol 2000

NOTES on the above table:

NOTE 1 – When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is sent to

the switchers, it will reset according to the present power-down settings.

NOTE 2 – These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if

the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the

HEX code

02 82 81 81

was sent from the PC, then the switcher (machine 3) will switch input 1 to output 1. If the user switched input 1 to output 1

via the front panel keypad, then the switcher will send HEX codes:

42 81 81 81

to the PC.

When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by

sending to the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION bit is set high).

NOTE 3 – SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory, (i.e.

those used for Store and Recall).

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.

NOTE 6 – If INPUT is set to 127 for these instructions, then, if the function is defined on this machine, it replies with

OUTPUT=1. If the function is not defined, then the machine replies with OUTPUT=0, or with an error (invalid instruction

code).

If the INPUT is set to 126 for these instructions, then, if possible, the machine will return the current setting of this function,

even for the case that the function is not defined.

NOTE 11 – For machines where the audio parameter is programmable.

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 will send its name. The reply is the decimal value of the INPUT and OUTPUT.

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):

7D 83 85 81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 5dec for 3rd byte).

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 (i.e. request the number of outputs)

would be HEX codes

7E 82 90 82 i.e. 16 outputs
