The new instrument firmware, now at version 1.06, adds additional error checking during the download via the CMC39 infra red interface adaptor. Some customers had reported trouble when downloading in varying levels of background lighting conditions. The software engineers have now added extra error checking during the transfer of the data blocks from the dBadge to the computer to minimize any failed data transfer.

If any errors now occur when sending a particular block of data due to the presence of stray IR light in the area where the download is happening then the software requests for the corrupted block to be resent until it is received safely. This adds a very slight delay to the download when there are many runs in the memory but significantly improves the reliability of the download process on those occasional difficult situations where errors are happening.

Due to the fact that IR light is invisible to the naked eye it is not always possible to spot when this may be a problem so this new improvement will help users get more reliable downloads should this problem arise.

All dBadges returned to Casella USA for annual recalibration will be automatically upgraded to the latest version of firmware and a new install CD will be provided to go with the kit of dosimeters. Otherwise, customers can download the small update file here and carry out the firmware upgrade themselves. The process only takes a couple of minutes per dBadge and uses the CMC39 IR adaptor to upload the new program into the instrument. A help file is included, PLEASE BE SURE TO READ THE HELP FILE BEFORE STARTING THE UPGRADE!!

Click here to download the zipped file to upgrade your own dBadges too. Save the file in a temp folder on your hard drive then unzip the 3 files and follow the instructions given in the text file UPGHELP.TXT.

Read the Upgrade HELP file here first before proceeding. All stored run data MUST be downloaded to dB35 BEFORE starting the upgrade as the memory will be lost after the upgrade has taken place.
