Title: Volume control buttons on CP...
Post by: Luckydevil on March 30, 2006, 10:01:15 pm: I want to make two of my admin buttons into volume controls (up and down). Now I have these on the keyboard attached to my ipac, but I'd like to be able to adjust it without opening the CP and I'm not using the two buttons anyways.

I'm not sure exactly what to tell the ipac to make these two buttons. It isn't a character that registers when I hit the volume control keys on the keyboard.

Any ideas?

Since they are keys on the keyboard they have to register at the computer as something. I just need to know what they register as so I can program my ipac.

So go into your IPAC programming and map those buttons to = and -. Just wire them to unused slots on the IPAC like sw7 and 8 or player 1 or 2.

Yes. It works really well. Highly recommended and relatively easy to do.

You could I guess. But for the effort it wasn't worth it to me. So I spent about $1.50 buying a potentiometer from radio shack and wired the speakers in line with that. That is the best solution, in my opinion, when compared to having dedicated control panel buttons for this.
