It has
1 stereo line-in
2 mono line-in
double stereo (front/back) line-out
12v input
2 "activation" inputs where you can put 12v on and do something in software depending on the state of that input (on or off).
Antenna is SMB, with an adapter available to motorola.
USB is an USB-B receptacle, use a standard USB cable.
Hope this enough info,
