A local GPS can be connected directly to a serial-port.

My Unit

This is the unit from which the position information will be updated using GPS.
The RF parameters must be set at 'Units properties' and at 'Network Properties'

Set-up port

• in 'Local GPS (NMEA 1083)' you set-up the GPS source. You can use a serial port or TCP client.
• select the com-port
• set the bit rate (mostly 4800 bps at NMEA)
• Choose the NMEA datagram you wish to use.
