As stated in reply #74, I am on FW 2.02.
There are (at least) two versions of the iCon 1:
Early version simply reads "iCon" on the front. This one supports all the tools listed above.
Later versions read "iCon 1". Those only support the iTool. Ersa split the iCon series into the iCon 1, 1C (remote control interface), 1V (Variotools etc.), 2 and so on for profit reasons I guess.
