Fuction | Instruction | Description |
Set attenuation value | FC ID 11 00 XX XX FE | XX XX is the attenuation value to be set(example:set 1 channel is 10dB,sending data is 1000,convert hexadecimal to 03 E8,then the sending data is FC 01 11 00 03 E8 FE |
Fine tuning | FC ID 12 00 XX XX FE | XX XX is 0~FFF |
FC ID 13 00 XX XX FE | ||
Fine tuning save | FC ID 14 00 00 00 FE | ID is the channel value to be set. |
