To receive Mode S TIS traffic data from a GTX 330 transponder on 

your GPSMAP 495, connect an available RS-232 OUT pin on the 

transponder to the Data In pin on the GPSMAP 495. (You do not 

need to connect the transponder to the GPSMAP 495’s Data Out 

pin.) Then, set the corresponding RS-232 output configuration on 

the transponder to REMOTE + TIS and set the GPSMAP 495’s 

Serial Data Format to TIS In or TIS In/NMEA & VHF Out. For

Transponder Installation Manual.

To output frequency data to an SL40 comm or SL30 nav/comm 

radio, connect the Data Out pin on the GPSMAP 495 to the RxD 

pin on the comm radio. (You do not need to connect the comm radio 

to the GPSMAP 495’s Data In pin.) Set the GPSMAP 495’s Serial 

Data Format to TIS In/NMEA & VHF Out or Aviation In/NMEA
