Harnessing Layout Overview

Usage of the FMX/TMX NMEA 0183 output only requires the addition of a T3H-G004 adapter to the T3H-C002 ECU breakout harness.

Parts Required

  • T3H-G004 - COMMAND Trimble NMEA Output Adapter

 


Connection Processimage.png

Connect the T3H-G004 adapter to Port C or Port D on the FMX display, or Port _ on the TMX.

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.

Connect the other end of T3H-G004 to the T3H-C002 ECU breakout harness.
