Q1040 I can’t seem to get the “Earthmate LT-20” GPS receiver to work with AirMail. Any suggestions?

1000 Airmail user software (HF)

A1040 The original Earthmate was connected via a serial port, used a Rockwell chipset and a non-standard interface at 9600 baud. Airmail can communicate with that device if you check the "Earthmate" box.

The 2003-vintage USB Travelmate was different, and worked in NMEA mode if you told
the DeLorme installer that you wanted to use the GPS with other applications also. If you made that selection when DeLorme was installed, then special drivers were installed that created a virtual com-port that would speak standard NMEA. In this mode the "Earthmate" box should NOT be checked, it is behaving as a standard NMEA GPS.

Apparently the same is true of the LT-20, except that the special NMEA-drivers are not part of the DeLorme installer. You can download the “DeLorme Serial Emulation Driver for USB Earthmate® GPS and Earthmate® GPS LT-20 Receiver” from
http://www.delorme.com/support/search.aspx
After the new driver is installed, start AirMail and configure the proper COM port for the LT-20 in the Message Index…..Window….Position Report…Data Input….Setup window.

Check the “GPS/NMEA Port Enabled” box, and select the proper COM port. Do NOT
check the “Earthmate” box. Also, be sure the “Data Input…Enabled” box is checked.
