18MODEL 2100 RS-232 PROTOCOL continued
Feedback Information:
Unsolicited feedback is sent anytime that the MODEL 2100 is controlled by IR remote, Front Panel or by RS232. Even if the MODEL 2100 is turned off it should send full feedback. Full unsolicited feedback will be automatic and in this format:
*G1 S3 M1 T0<CR>
*= Start of transmission <CR> = End of transmission
G0 = Power Off, G1 = Power On
S1 = Input 1, S2 = Input 2, S3 = Input 3, S4 = Input 4, S5 = Input 5, S6 = Input 6 S7 = Input MP3, S8 = Input Bypass
M0 = Mute Off, M1 = Mute On
T0 = Tone Off, T1 = Tone On
Volume Feedback *V0<CR> and *V1<CR>
Because the volume control is a motor driven type there is no exact feedback of the current volume setting. When the volume is turned up or down from the remote or RS232, feedback will be transmitted confirming the volume was increased or decreased. This will be represented by a “*V0<CR>” for volume decrease and “*V1<CR>” for volume increase.
You can request the status of the MODEL 2100 by issuing the following commands:
