OK, this is a seriously geeky question, so those of you that hate data protocols might want to exit now....
I'm curious if anyone has looked into the serial I/O protocols from the XM antenna/receiver used on the 396/496's. I'm curious if it is a one way "broadcast" communication, where the receiver just umps out data to whatever is listening, or if it requires a two-way handshake.
Why am I interested? Well....if it is a one-way transmit type thing, one could theoretically build a "Y" cable and feed two 396/496's in the same airplane with one XM receiver - for instance one in the front seat, and one in the back seat of an -8......Since this appears to be a USB connection (it must be - you use the same port on the 396 to connect to a PC USB port), it might be possible.
Of course, I am pretty much a novice on USB protocols - RS-232 I understand, but this newfangled stuff....
OK geeks, what do you think?
