Download Files to USB Device

On Files, you can sync files (uploaded to a site) to the site’s assets [if they have paired EC520 grade control devices (GCDs)].  

However, there may be the following instances where this isn’t possible:

  • Usage of legacy CB460 GCDs.

  • Not having the required asset subscription and optional plan.

  • Disrupted network or unavailability of cellular internet on the site.

Despite these obstacles, you can now directly download files (uploaded to a site) onto a USB device. You can then plug the device into the asset and transfer the files to the onboard display.

This is supported for the following GCDs:

  • EC520 and EC520-W (Cat Grade or Trimble Earthworks)

  • CB460 (Cat AccuGrade or Trimble GCS900)

Unzipping and Transferring Files to a USB Device

After downloading the zipped files onto your device, you’ll need to unzip them before transferring to your USB device. Otherwise, the files won’t be read by the asset.


• For optimized performance, it's recommended to use a USB device the fits the following criteria:
         ◦ Metal housing
         ◦ FATF-formatted
         ◦ Minimum 16GB storage space
• Ensure the USB device is empty and doesn’t contain any pre-existing content.

To unzip and transfer files:

  1. Navigate to the folder path where you placed the downloaded files.

  2. Right-click the file and select Extract All.

  3. On Extract Compressed (Zipped) Folders, select which folder you want the unzipped files placed in. Or you can leave it as the default (which places the folder in the same place as the zipped file).

  4. Click Extract.

  5. Open the folder.

  6. The subfolders displayed vary depending on which grade control device you selected when downloading the files. They can be one or all the following:

    • Machine Control Data: Applicable for CB460 devices (Grade/Earthworks).

    • ProjectLibrary: Applicable for EC520 and EC520-W devices (AccuGrade/GCS900).

  7. Open the respective folder(s) to find your files categorized in corresponding subfolders (for example, Design containing design files and Geodata containing geodata files).

  8. Select the main folder(s) and either right-click > select Copy or press Ctrl+C.

  9. Navigate to the USB device root directory path on your computer. You can find this under This PC.

  10. Either right-click > select Paste or press Ctrl+V.

  11. Once pasted, safely eject the USB device. Insert it into your respective grade asset display and transfer the files.
