Firmware Refresh/Module Recovery using the HarvestMaster Service Utility

10 Feb 2025

Description

The HarvestMaster Service Utility is used for multiple purposes. This technical note will describe how, on your HarvestMaster system, to use this utility when trying to recover a DSP or Actuator module which is exhibiting a fault, no communication, or red LED error indicator light.

With instruction from a HarvestMaster support representative, the Service Utility can also be used for upgrading or downgrading the firmware on all electronic modules on HarvestMaster GrainGages, Planter/Sprayer Controls, and other HM Generic Harvest Systems.    

Steps for Module Recovery

  1. Identify the type of module exhibiting the fault. You can find that using the silkscreen label on the face of the module.
  2. Ensure your GrainGage, Planter/Sprayer Controls, or Generic Harvest System device is powered ON and connected to your tablet through the Controller as normal.  
  3. With Mirus closed, open Windows File Explorer on your Tablet.
  4. Navigate to "C:\HarvestMaster\Mirus\Devices\H-SeriesGG\Tools" and open the HM.ServiceApp.exe. 
    1. Under “ID Name” you will see your HarvestMaster Modules connected.
    2. To the right of the Module, you will see its current firmware version listed.
    3. If you do not see any modules listed, verify that your Grain Gage is connected to the tablet via the Controller, and press the refresh button in the bottom right corner of the Service App. 

Note: Your faulty module may not show a current firmware version listed.
