RX:
Input Gain and Output Volume Control:
UPDATE GAINS-PHASE: CMD=01H
A. The User has to send the following Command, including the value to be assigned to “Vol”, for
Modifying the Input Gain (Chn =: 0, 1) or the Output Volume (Chn =: 2, 3).
Also the Output signal Phase can be modified:
TX:
xx = 0,...,31 (ID device)
Chn=0,...,3: Channel selected, 0, 1=In1, In2; 2, 3=Out1,.Out2; when Channel 0, 1 selected,
then Vol=Input
Gain, when Channel 2, 3 selected, then Vol= Output Vol.
Pha= Phase only if the Chn>1; Value=0, 1 where 0=direct, 1=inverse (180')
Vol= Gains from 0 to 180 (-12dB/ +6dB step 0.1dB)
B. If the command has been properly executed and the Gain/Volume modified, then the
Microcontroller will send back to the User (eg Crestron/AMX Remote Control..) the same frame
used by the command:
