Sorry to drag up this old post. I was musing in another thread about the possibility of decoding an aftermarket protocol like Pioneer's IP-Bus so that the empeg could control a satellite radio receiver. I found this page where a guy made a IP-Bus - RS232 adapter. Anyone else interested in the possibilites of this? Best of all...his C code for IP-Bus control is GPL'ed and available on the site.

EDIT: you know you're dredging up an old post when Patrick is a newbie...
