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.

Connection Process

1. Connect the John Deere Front Extension Harness to the ISOBUS breakway connector. 

2. Route along the implement, allowing slack at pivot points and avoiding snag hazards.

3. Connect the T3H-S001 adapter to the Front Extension Harness.

3. Connect the PF81137 Implement Pigtail Terminator to the Implement Receiver Wiring Harness and secure the terminator to the implement receiver wiring harness.

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.

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

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