For older CmDongles with a specific controller version, there is no firmware version 2.x, because these controllers do not possess sufficient memory for the changed firmware update procedure that was introduced as part of version 2.0. However, future firmware updates will provide error corrections for these CmDongles, which are then delivered as version 1.xx using the Update Server.

The following CmDongle item numbers will permanently be limited to firmware versions 1.x: 1001-01, 1010-01, 1011-01. On CmDongles with standard casing, you can find the item number on the bottom of the case.
