Kramer Protocol 2000

NOTE 19 – When data (ie. 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 20 – To store data in the non-volatile memory of the unit, e.g. the EEPROM for saving SETUPS. The EEPROM

address is sent using the INPUT byte, and the data to be stored is sent using the OUTPUT byte. To use this instruction, it is

necessary to understand the memory map, and memory structure of the particular machine.

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
