Leica mojo3D, NMEA Output
11 NMEA Output
General informa-
tion
• NMEA 0183 is a standard developed by the National Marine Electronics Associa-
tion. The standard applies to communication between devices such as GPS
receivers, echo sounders, sonars, anemometers, other marine devices, and a
range of instruments.
• NMEA output is via the serial connection on the optional mojo3D Port Expansion
Cable. The mojo3D on its own is capable of outputting position information in
NMEA format.
• If the Electric steer kit with the Leica Twist or if the Leica mojoRTK or Leica
mojoXact is added as an attached device, then NMEA output with terrain
compensation will be produced.
Limitations • The mojo3D provides support only for the NMEA 0183 standard.
• The mojo3D does not support flow control.
• The mojo3D supports different baud rates, but the baud rate selected may limit
how many sentences can be output and the rate at which they are output. For
example, at low baud rates it is not possible to output all sentences at 10 Hz. The
mojo3D will detect this situation, display an error, and disable NMEA output. If
you receive this error, switch to a higher baud rate or reduce the number and/or
rate of sentences to be output.
