Prescriptions

Prescribe implement behavior using maps that you can adjust any time

Updated September 13, 2021

Your fields are not uniform, and neither is your treatment of them. By adding prescriptions to your 20|20 system, you can let it know which parts of your field need to be handled differently.

Import Prescriptions onto Your 20|20

If you have external prescriptions that you'd like to use on your 20|20 system, you can import them with a USB drive.

Before you begin, make sure that each prescription is saved on your USB drive in either .2020 format or as a set of three shapefile-based files (.shp, .dbf, and .shx).

All files must be saved at the top level of the USB drive or in a folder called SendTo2020. If they are hidden in other folders, the 20|20 will not be able to find them.

Once you're ready,

  1. Insert the USB drive into the port on the left side of your 20|20 monitor.
  2. Navigate to the Data page.

    • From the Home screen, press Setup (bottom right).
    • Then press Data (bottom right).
  3. Press Import (top right) and then Prescriptions (top center).
  4. Select which system the prescription applies to: Seeding, Liquid, Granular, or Depth.
  5. A popup will appear, listing available files. Select which ones to import by tapping on them, then press Import.

  6. Optional – If you want to use a single prescription file for multiple systems, repeat steps 4 and 5 for each system.

Assign Prescriptions to Specific Fields

Once you have prescriptions imported into your 20|20, you will need to assign each one to its intended field.

  1. Navigate to the Fields page.

    • From the Home screen, press Setup (bottom right).
    • Then press Fields (top right).
  2. Select the appropriate Client, Farm, and Field for the prescription you want to work with.
  3. Select which system the prescription will be used for: Seeding, Liquid, Granular, or Depth.
  4. Find and select the prescription to use for this field by tapping on the prescription file box to browse existing prescriptions.

  8. Optional – If you want to assign prescriptions to additional fields, repeat steps 2-7 for each one.

Use Prescriptions to Control Your Implement

After you have assigned a prescription to an active field, you can use it to control the implement.

  1. From the Home screen, press the control button for the system you want to control, such as vDrive, mSet, Nitrogen, Depth, and Granular.
  2. Toggle the system from Manual to Prescription control at the top of the screen. When Prescription is selected, the system will be controlled by the assigned prescription.

    Below is the screen. Notice the active Prescription toggle on the center right

Export Prescription Files

If you've made changes to a prescription since importing it, you may want to save it for future use. You can do that by exporting it to a USB drive.

  1. Insert a USB drive into the port on the left side of your 20|20 monitor.
  2. Navigate to the Data page.

    1. From the Home screen, press Setup (bottom right).
    2. Then press Data (bottom right).
