Hello,
I have two DT80 Series 2 and one DT80 Series 3 with firmware versions 9.10.4890 and 9.14.5407, respectively. I want to update them to version 9.18 or even higher to be able to use the dEX software or dEX 2.
Do I need to install each version one by one, or can I directly install the latest version, which is 9.26? Or should I install an older version that works well with all my sensors and settings?

Thank you for your help.

Hi jport,

You can upgrade the firmware directly to 9.26, there is no need to perform a step upgrade.

Please download the firmware from this link: https://downloads.thermofisher.com/ANZ_Software_Uploads/DT80-9261045-usbdisk.zip
