Shared signal provides the functionality when pairing two receivers with AutoTrac™ Implement Guidance, Active Implement Guidance™, Machine Sync combine harvest automation, or AutoPath™ software via the GreenStar™ 3 2630 Display, Generation 4 4600 CommandCenter™, or 4640 Universal Display. Shared signal allows correction signals to be communicated between a pair of receivers, improving relative system accuracy and reducing the initial investment required to use AutoTrac Implement Guidance, Active Implement Guidance, Machine Sync combine harvest automation, or AutoPath.
- NOTE: When using shared signal, the leader must have the higher correction level.
- In an AutoPath application, shared signal uses the correction level of the leader.
- In a Machine Sync application, shared signal uses the correction level of the leader.
Supported configurations
All StarFire 3000, StarFire 6000, and StarFire 7000 Receivers are compatible with shared signal and can be used interchangeably.
- The system uses the correction level of the leader. It is important to place the receiver with the highest correction level on the leader.
NOTE: StarFire 3000 Receivers must be updated to 20-2 (2.80S), and StarFire 6000 Receivers must be updated to 20-2 (4.40N). Once both leader and follower are updated to this software, there are no configuration limitations on leader/follower setup between receiver models.
- Leader: the tractor receiver for AutoTrac Implement Guidance, AutoPath, and Active Implement Guidance, or the combine or harvest operation (pull-type harvester) receiver for Machine Sync combine harvest automation.
- The leader’s correction level determines the correction level of the follower.
- For highest accuracy or for implement guidance applications, the leader must have the higher correction signal.
- Follower: the implement receiver for AutoTrac Implement Guidance and Active Implement Guidance, or the grain cart tractor receiver for Machine Sync combine harvest automation.
- The follower may have the lower correction level, but the overall system accuracy matches the accuracy of the leader.
AutoTrac Implement Guidance and Active Implement Guidance
Shared signal enables StarFire receivers to share information when paired using implement guidance. This allows a StarFire receiver using a lower accuracy to be used on the implement for an implement guidance system and take advantage of the higher accuracy used by the machine receiver. The following table describes the accuracy expected from this system:

AutoPath
Shared signal enables StarFire receivers to share information when paired using AutoPath.

Machine Sync combine harvest automation
Shared signal enables StarFire receivers to share information when paired using Machine Sync combine harvest automation. This allows the two vehicle receivers to maximize system performance during harvest. To ensure optimal performance and compatibility, always update receivers to the most current software version available on StellarSupport™ portal.
