RoadRelay 4 Software Download

Each of the RoadRelay 4 software calibrations is in a zip file. The calibration tool install program sets up the correct COM port, data link, and protocol so that a RoadRelay 4 software calibration can be downloaded to your RoadRelay 4. The steps for running the RoadRelay 4 software download are listed below.

1. Make the proper connections between the PC you are using to download the RoadRelay 4 software and the RoadRelay 4. You can either use the RS-232 data extraction cable (only for 40059XX models of the Roadrelay 4) between the RoadRelay 4 and the PC, or you can use a Cummins INLINE adapter and data link cable interface between the PC and either the J1708/J1587 or J1939 public data link. If you have a 40032XX model of RoadRelay 4, you must use the data link interface option.
2. Turn the vehicle key switch to the "On" position.
3. Check the model number (40059XX or 40032XX) of your RoadRelay 4 (you can find this on the label on the back of the unit) and also check the software bootloader and application versions by pressing key 5 and selecting "Software Version."
4. Download one of the RoadRelay 4 zip files by clicking on the desired button above (the "A" calibration is the standard calibration for RoadRelay 4 and works with all models, while the "E" extended memory calibration is for Portuguese and Italian language support and will work only on 40059XX models).
5. Unzip the calibration file and save it in whatever folder you prefer on your PC.
6. Run the RoadRelay 4 calibration tool executable program.
7. Select the correct PC COM port, data link, and protocol. Choose the calibration file you just downloaded into your preferred folder.
8. Select "Start." The calibration tool utility will now download the latest software calibration into your RoadRelay 4. The RoadRelay 4 will "beep" twice and the display will go blank. It takes approximately 5 minutes to download a calibration over the J1939 data link, while it takes about 25 minutes to download a calibration over the J1587 data link or the RS-232 serial port.
9. After the download has completed, verify that the correct software is now in your RoadRelay 4 by pressing key 5 and selecting "Software Version." The bottom number is the application version and it should match the name of the ".cal" file you just downloaded.
