  • Page 37: Appendix - Remote Control Commands

    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)
  • Page 38 APPENDIX – REMOTE CONTROL COMMANDS The command data format is: Wavelength, Program Wavelength 1 ( bytes ) 0 = wavelength 1, 1 = wavelength 2, 2 = wavelength 3, 3 = wavelength 4 Attenuation, REL attenuation, REL value, Program start Value, Program Finish Value: value = 37.75 dB.
