Parts Required

  • T3H-G004 - COMMAND Trimble NMEA Output Adapter

Connection Process

  1. Connect the T3H-G004 adapter to Port C or Port D on the FMX display, or Port _ on the TMX.
  2. A port replicator is supplied in case the port was already in use for something else, if so disconnect the device, connect T3H-G004 and then reconnect the device using the port replicator on T3H-G004.
  3. Connect the other end of T3H-G004 to the T3H-C002 ECU breakout harness.
  4. Follow the setup process below for activating the NMEA output port on the FMX/TMX system.

Activating the NMEA Output

  1. Make sure that if present, Autopilot is configured for use on Port A - this leaves Port C and Port D free for NMEA output of either implement receiver.
  2. Select the GPS Receiver listed below Autopilot [Vehicle] and press "Setup".
  3. Press GPS Output
    1. Select Output Port > A (ext. GPS)
    2. Message rate > 5Hz
    3. Baud Rate > 38400
    4. Maximum GGA Quality > 0
    5. Lat/Lon Precision > 8
  4. Press the "NMEA Messages" Tab.
  5. Set GGA, VTG and GSA to "On". Leave all other messages set to "Off".
