8.5 | NMEA 0183

NMEA 0183 Serial (RS232) capable receivers can be connected to the COMMAND system. 

IMPORTANT: If the GNSS receiver does not provide terrain compensation, an IMU must be installed to maintain accuracy.

Parts Required

  • BPF11284 - Front Extension Harness (10m)
  • PF81137 - Implement Pigtail Terminator Wiring Harness
  • T3H-S001 - COMMAND Impl Adapter – Stub Junction
  • T3H-G001 / T3H-G007 - COMMAND NMEA Extension Harness (8m or 12m)
  • Custom GNSS Adapter - Custom adapter for connection of the NMEA 0183 Serial compatible receiver to the T3H-S001 and T3H-G001/G007 adapters.

4. Connect the CUSTOM adapter to the T3H-S001 adapter.

5. Connect the CUSTOM  adapter to the receiver's port ensuring connector keys are lined up.

6. Connect the NMEA extension harness T3H-G001 or T3H-G007 to the CUSTOM adapter, then connect the other end to the T3H-C005 external breakout harness.

Receiver Configuration

Perform necessary setup of the GNSS receiver using provided manufacturer tools or programs:

    • Talker ID should be set to GP
    • Messages enabled - GGA, GSA, VTG
    • Output Update rate - 10Hz recommended
    • Baud Rate - 38400

Verify:
- Receiver powers on
- GNSS data is being received by COMMAND
