If you have successfully updated a device (receiver, Central Box, sensor, etc.) to the latest version of the FW, in which there are new setting options and functions are available, then the latest “Devices” definition files have to be uploaded to the transmitter prior to effectively use the new features. These "device definition" files in the transmitter show all the possibilities of the new features.

If you only see the ID number of the receiver in the JETI DC / DS transmitter (device explorer) and its settings can’t be opened, it's necessary to update it to a newer FW. Older versions of the FW didn't support these setting possibilities.
