[App_rpt-users] LOX and CAT 1000 Interfacing

Hi,

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!
