I just received my lox and beagle board a few weeks ago and I'm trying to interface it with the remote base port on our CAT 1000. I'm interfacing the LOX DB9 with the CAT 1000 DB9, but I'm not sure if I have the pinout done correctly or not. 

Should the pinout be:

LOX <> CAT 1000

GND <> GND

CTCSS <> CTCSS

PTT <> COR

AUDIO OUT <> AUDIO IN

AUDIO IN <> AUDIO OUT

COR <> PTT

or should the pinout be 1:1, ie:

GND <> GND

CTCSS <> CTCSS

PTT <> PTT

AUDIO OUT <> AUDIO OUT

AUDIO IN <> AUDIO IN

COR <> COR

To interface the two boards, I'm using a DB9 to RJ45 on both ends and a straight through cat5 to connect the two.

Thanks for any help!
