I intend to use the serial output from a Garmin 296 unit to send VHF frenquencies to a Garmin SL40 comm. I would also like to use the same output line connected to a D120 EMS. To get the VHF frequencies to the SL40, the com output mode has to be set as "NMEA & VHF Out". The serial stream will send both NMEA data & VHF frequencies over the same line. I contacted Garmin support to find out about the "fast" & "normal" output modes & if this confiquration would work. They did not know if the Dynon could filter out the VHF data.
The question is, will the Dynon filter out the VHF info & only read the NMEA data it needs to function?
