WC IN | Connecting a third party receiver
AutoTrac requires CAN GPS messages from an original StarFire receiver or StarFire iTC receiver. Non-John Deere GPS receivers that output correct NMEA 0183 standard messages can be used for documentation and manual guidance with a GreenStar application. It is critical that receiver is setup to output the following messages:
GGA
GSA
RMC setup at 19200 baud (This is fixed and Non-adjustable)
Data bits 8
Parity none
Stop bits 1
Flow Control none
1 or 5 Hz output rate (Recommend operation at 5 Hz. Guidance requires 5 Hz.)
Without these messages, receiver will not function with GreenStar application. From the receiver manufactures wiring diagram, determine which wires from the receiver are the signal transmit and signal ground. Verify that Receiver Transmit connects to Pin 3 of the DB9 connector and receiver ground connects to pin 5 of the DB9. Look at the front face of the connector to see the pinout number designation.
