APPENDIX – REMOTE CONTROL COMMANDS
There are around 50 commands for communicating between a controller ( computer ) and the attenuator.
The commands sent to the attenuator are transferred as a block of bytes in binary form with an inverted checksum byte, and on completion of the
command, the attenuator responds with the checksum byte with the following structure:
Command byte | Data byte 1 | Data byte 2 | Checksum byte
Checksum byte = the complement of (Command byte + Data byte 1 + data byte 2)
The return commands sent by the attenuator to controller are transferred as a block of bytes in binary form with an inverted checksum byte as
follows:
Data Byte 0 | Data Byte 1 | Data Byte 2 | Checksum Byte
Checksum byte = the complement of (Data byte 0 + Data byte 1 + data byte 2)
The approximate equivalent key press or user activity is shown in (brackets).
