Connecting the Internal GPS Receiver to your Application As explained in GPS Ports Configuration on page 46, the COM2 port in MobileMapper CX is a virtual COM port named "GPS VSP Output" and has fixed settings: 57600 bauds, 8 data bits, 1 stop bit and no parity bit. This virtual port will input GPS positions to off-the-shelf Windows CE mobile mapping applications running on MobileMapper CX. To do this, you just have to select "COM2" in your mobile mapping application as the source of GPS data. COM2 can therefore provide the mobile mapping application with NMEA-formatted data coming from the internal GPS receiver. You can define the NMEA sentences you would like to output through this port from the NMEA tab in the GPS Ports Configuration utility (see page 46). 17
