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, 2, 3) or the Output Volume (Chn = 2, 3, 4, 5, 6, 7, 8, 9).
Also the Output signal Phase can be modified:
TX:
STX ID_M ID_N
CMD D0 D1

D3
D4
D5
D6 D7 ETX
F0H C3H XX 01H Chn 00H

00H
Phs Vol F7H
XX = 0,..,31 (ID device)
Chn=0,...,7: Channel selected, 0, 1, 2, 3=In1, In4; 2,...,9=Out1,..,Out8; when Channel 0, 1, 2, 3 selected, then Vol=Input
Gain, when Channel 2, 3, 4, 5, 6, 7, 8, 9 selected, then Vol= Output Vol.
Phs= 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:
