Jon,
The flarm needs to be configured to send data out via either (or both) of the RJ or DB9 port. This is done in the flarm config file
Assuming you are using the standard LX-PFcore connection cable connecting to the flarm DB9 port, then put this code in the config file. It's what works with my core and 9000.
# configure D-SUB 9 port
$PFLAC,S,NMEAOUT2,63
If using the RJ port then use:
# configure PF core RJ-45 / PF portable port
#$PFLAC,S,NMEAOUT1,63
#$PFLAC,S,BAUD1,2
