NMEA 0183
Relevant Receiver Models
This section is aimed at connecting NMEA 0183 Serial (RS232) compatible receivers to the COMMAND system.
NOTE: Some GNSS receivers DO NOT possess an internal IMU for terrain compensation purposes. If the receiver doesn't have terrain compensation, we highly recommend running a X-Slope IMU on the implement in this situation so that Level COMMAND can apply the necessary terrain compensation to maintain accuracy with drain batters and other steeper slopes.
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
- Connect the John Deere Front Extension Harness to the IBBC and route it along the hosing/implement making sure to leave some slack wherever the hitch might flex but also paying close attention to any objects that could get caught on the harnessing.
- Connect the T3H-S001 adapter to the Front Extension Harness.
- Connect the Implement Pigtail Terminator to the T3H-S001 adapter and secure the terminator to the implement receiver wiring harness.
- Connect the CUSTOM adapter to the T3H-S001 adapter.
- Connect the CUSTOM adapter to the EMLID receiver's LEMO port carefully ensuring the red dot key is lined up.
- Connect the NMEA extension harness T3H-G001 or T3H-G007 to the CUSTOM adapter, then connect the other end to the T3H-C002 ECU breakout harness.
- 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
- Check that the receiver powers up correctly and that data is being received by COMMAND.
