NMEA output from Pixhawk2


In my currrent setup i have Emlid M+ connected to GPS2 on Pixhawk2. I wanted to know if there is any way i can configure a port on Pixhawk2 to output these NMEA sentences? If so, can anyone guide me and the related wires i will need…
I basically need NMEA output from a port on Pixhawk2 going to input on a Ground Penetrating Radar which has a RS232 connector.
