Does anyone have the pinout for the DPC550 available?
I want to combine:
a. External roof antenna.
b. Hands-free earphone/mic headset.
c. External 12V cigarette lighter power adapter.
d. Three watt booster kit.
The external antenna isn't a problem since it screws into either the
TNC connector the 3-watt booster, or with and adapter into the SMA
connector on the top of the phone.
But all the other things plug into the same 8 pin port on the bottom.

I'll bet that's data sent on a shielded, twisted pair with
"True" and "Complement" data sent on TRU and CMP, and the
shield connected to RTN ("Return").
