Download a calibration to a Programmable Datalink Device
Use the Equipment Dashboard to find a Programmable Datalink Device (PDD) and transfer a calibration to it.
Expected result
The PDD is detected, opened, and receives the selected calibration through the standard calibration process.
Important notes / prerequisites
Connect the service computer to the equipment and open the Equipment Dashboard. The PDD must be detected before it can be opened.
Important: When using Calibration Files to download the PDD calibration to the PC or mobile device, select Programmable Datalink Devices. The page defaults to Engine Controller; leaving that selection unchanged can return the wrong calibration results.
What is a PDD?
A Programmable Datalink Device is a connected Cummins device that can receive a calibration through DTK. A PDD may be an engine-related component or an emissions, charging, or air-handling device rather than the engine ECM itself.
Examples technicians may see include turbochargers, dosers, and smart alternators. The device name displayed in DTK depends on the equipment and connection.
Note: This is an example list, not a complete list of supported PDD devices. Use the device detected by Scan for Public Cummins Devices.
Windows procedure
- From the Equipment Dashboard, select Scan for Public Cummins Devices.
- Wait for the device scan to complete.
- Select the detected PDD device. The device should be clickable so you can open it.
- Open the PDD and select Calibrate.
- In Calibration Files, select Programmable Datalink Devices instead of the default Engine Controller before searching for or downloading the calibration.
- Follow the standard calibration process to select and transfer the calibration to the PDD.
- Wait for the calibration transfer to complete and verify the result.
Common problems
If the PDD is not listed or cannot be selected, scan again from the Equipment Dashboard and verify the connection before continuing.
DTK Mobile differences
DTK Mobile uses the same calibration screens and PDD workflow as DTK Windows. Follow the procedure above: scan for Public Cummins devices, select the PDD, open Calibrate, and select Programmable Datalink Devices in Calibration Files before searching or downloading. Follow the displayed transfer instructions and verify completion.
