Generation 4 Displays Software Update 20-1 Release Notes

Onscreen Operators Manual

A copy of the Generation 4 display operators manual is now available within the Help Center application on the display. This content will be updated with future software releases. Supplemental onscreen help pages are also available via Help Center. Always read the latest Operator's Manual before operation. Obtain a copy from your dealer or visit techpubs.deere.com.

Guidance

Operators can now create a duplicate track in the guidance application for straight tracks and AB curves. Duplicate track creates a copy of the active guidance track, defaulting the new name to the original track name plus "(1)". The track name can be modified. The new track can be centered on the machine or shifted left or right. If the original track used the A + Heading or Lat/Lon + Heading method, the new track heading can also be modified.

Note: Track spacing for duplicate tracks cannot be modified. Ensure correct track spacing is set up before creating a duplicate track.

Diagram: Shows the 'Edit Guidance Track' interface with fields for Track Name, Method, and Heading, and buttons for 'Duplicate', 'Cancel', and 'OK'. An arrow points to the 'Duplicate Track' interface, displaying 'Track Attributes' with fields for Name, Field, Client/Farm, Heading, and Shift Increment, along with navigation buttons and 'Cancel'/'OK' buttons.

AutoTrac™ Health

The AutoTrac™ Health page is available in the diagnostics center to monitor tracking performance, conditions, GPS health, and resume switch status. Tracking performance and conditions are continuously calculated when AutoTrac™ is active (4/4 status). Values do not update when AutoTrac™ status drops to 3/4 or 2/4, and display "---" at 1/4 status. Tracking performance values are shown as a 95th percentile.

Diagram: Illustrates the 'AutoTrac Diagnostics' screen with stages like 'Install', 'Configure', 'Enable', 'Activate', and a 'Health' section. An arrow points to the 'AutoTrac Health' screen displaying 'AutoTrac Status' (Active/Off, Last Exit Code) and 'Tracking Performance' metrics like 95% Off-Track Error, 95% Heading Error, and Yaw Rate, along with 'Conditions' like Surface Roughness and Wheel Slip.

Information available on AutoTrac™ Health page:

• AutoTrac™ Status: Displays the AutoTrac™ pie chart and steering on/off toggle.
• Last Exit Code: Indicates why AutoTrac™ most recently deactivated or why it does not activate.
• 95% Off-Track Error: Distance from the closest track to the machine. Values should be equal to or less than the following in good conditions:

95% Heading Error: Relationship of machine direction to the current track. Values should be equal to or less than the following in good conditions:

95% Yaw Rate: Machine rate of turn affecting tracking performance. Values should be equal to or less than the following in good conditions:

Surface Roughness: Measures surface condition using pitch, roll, and speed from the StarFire™ Receiver. A value over 50 may negatively impact AutoTrac™ performance. Outside optimal range shows a yellow LED status indicator; within optimal range shows a green LED status indicator.

Wheel Slip: Percentage of wheel slip compared to GPS speed. Over 6% may negatively impact AutoTrac™ performance. Outside optimal range shows a yellow LED status indicator; within optimal range shows a green LED status indicator.

Accuracy: Position accuracy of the receiver, displayed as a percentage. 100% accuracy is required for advertised performance.

Signal Strength: Quality of the StarFire™ correction signal.

AutoTrac™ Resume Switch: Indicates On when pressed, Off when released.

Single-line Shift

Operators can now temporarily adjust the position of a single guidance line left or right without affecting the original track's location or shape. The single-line shift resets to zero at the end of a turn or when a new line is selected. It can be applied up to 40% of track spacing, and AutoTrac™ remains active. A new single-line shift run page module is available in the guidance application and can be added via Layout Manager. This option is available for straight tracks and AB curves.

Diagram: Shows the 'Guidance 1' interface with map view, current track information, and controls. A finger icon points to the 'Single Line Shift' feature, indicating its adjustment.

COM Port Settings

A diagnostics page for RS232 devices is now available under COM port settings to help customers and dealers diagnose RS232 communication issues more quickly.

Diagram: Shows the 'COM Port Settings' screen with options for COM Port 1 and COM Port 2, including Device Type and Manufacturer. An arrow points to the 'COM Port Diagnostics' screen, detailing 'Device Type', 'Communication Status', and data messages like GGA, GSA, RMC, and Speed.

Information available on the COM port diagnostics page:

• Device Type: User-selected value (Serial GPS, GreenSeeker®, N-sensing, Field Doc™ Connect).
• Manufacturer: User-selected value.
• Communication Status: Indicates if the COM port device is sending messages; becomes inactive if no message is received within 10 seconds.
• GGA: Essential fix (position) data providing 3D location and accuracy. Active status means the display is receiving this data.
• GSA: GPS dilution of precision (DOP) and number of satellites used. Active status means the display is receiving this data.
• RMC: NMEA version of GPS data (position, velocity, time). Active status means the display is receiving this data.
• Speed: Speed value received from serial GPS.
• AR Message: Required from Field Doc™ Connect control unit for proper operation. Active status means the display is receiving this data.
• RC Message: Required from GreenSeeker® control unit for proper operation. Active status means the display is receiving this data.
• D2 Message: Required from the nitrogen sensor for proper operation. Active status means the display is receiving this data.

Activations

Installation of 20-1 software transitions Data Sync activation into base functionality. Any display installing 20-1 software will receive the Data Sync activation during installation.

Fields & Boundaries

Base station settings for John Deere RTK radio 869 can now be saved to each field and automatically recalled. This feature saves RTK settings from the StarFire™ VT page to the selected field. Saved RTK settings are recalled when the field is selected. RTK settings can still be manually changed via the StarFire™ VT page. This feature requires enabling via the Fields & Boundaries application, then Advanced Settings. Saved RTK settings can be imported/exported via USB. This feature is available for John Deere RTK Radio 450 or 900 with 19-2 or newer display and receiver software.

Requires: StarFire™ 6000 receiver with 20-1 or newer software, John Deere RTK Radio 869, and Generation 4 display with 20-1 software.

The most recently used boundary offset values from the GPS offset point for driven boundary creation will now persist on Generation 4 displays. If a value is modified, the "Start Recording" button must be selected to save the change. These values reset to default only upon a factory data reset. This eliminates the need to manually enter values each time a new boundary is recorded. This change does not affect boundary offset values from the offset point associated with the implement/work point.

Diagram: Shows the 'Fields & Boundaries' interface for 'Create Driven Exterior Boundary'. It displays 'New Boundary Offset Point' options (GPS, Implement/Work Point), 'Offset Location', and 'Boundary Offset' value, with buttons for 'Cancel' and 'Start Recording'.

Overlap Control

Overlap Control now allows operators to manually turn off a section or group of sections. This feature improves documentation accuracy for areas not being harvested or areas with crop damage. For platform headers, operators can configure 2 to 24 manually controllable groups. If the number of groups does not equally divide the header width, smaller groups are placed on the outside edges. For row crop headers, each row is manually controllable, and the number of groups cannot be adjusted. If more than 12 groups are configured, a left/right toggle button allows switching between manual control of the left and right sides of the header. Manual control can be used with automatic control. Manually disabled groups override other section states and display with a black fill color.

Diagram: Shows the 'Overlap Control' interface with Master, Headland Control, and Boundaries settings. It includes 'Manual Overlap Control' with 'Number Of Groups' and 'Total Width', and controls for 'Enable All', 'Left', 'Right', 'Disable All', and individual section widths.

Section Control

Generation 4 displays can now visualize the Section Control look ahead on the map. This is calculated based on mechanical delay times and machine ground speed. The front line of the look ahead window indicates where an ON or OFF command needs to be sent to accurately start or stop product flow at the work point relative to the desired ground location. This tool optimizes operational behaviors to reduce operator-induced errors in Section Control performance. For best results, avoid changing ground speed or heading while the look ahead window is in a command transition area.

Diagram: Shows the 'Section Control' interface with a map view displaying a 'look ahead' line. The 'Information & Settings | Section Control' panel shows options like 'Continuous Tillage' and 'Visualize Mechanical Delay Look Ahead'.

Flags

The flag icon size has been increased in the perspective map view for easier viewing.

Diagram: Compares flag icon sizes in perspective map view for '19-3 and prior' versus '20-1'.

Mapping

A map layer for varieties has been added to planting and seeding operations. Up to ten different colors are used to distinguish varieties; colors repeat if more than ten varieties are used. This map layer is available if one or more varieties have been used within the current field.

Diagram: Shows the 'Guidance' interface with a map displaying 'Variety Map' layers, including a 'Map Legend' listing 'VARIETY9' through 'VARIETY4'.
