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, 4, 5, 6, 7).

Also the Output signal Phase can be modified:

TX:

STX ID_M ID_N CMD D0 D1 D2 D3 D4 D5 D6 D7 ETX

F0H C3H XX 01H Chn 00H 00H 00H 00H 00H Phs Vol F7H

XX = 0,..,31 (ID device)

Chn=0,...,7: Channel selected, 0, 1=In1, In2; 2,...,7=Out1,..,Out6; when Channel 0, 1 selected, then Vol=Input

Gain, when Channel 2, 3, 4, 5, 6, 7 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:

RX:

STX ID_M ID_N CMD D0 D1 D2 D3 D4 D5 D6 D7 ETX

F0H C3H XX 01H Chn 00H 00H 00H 00H 00H Phs Vol F7H

1 2 ... 55 56 57 58 59 60 61 62 63 64 65 66
