Updates
The E-Stim Systems 2B contains on board programs, the 'Firmware', that can be updated by the user. To do so you will need a PC or Mac computer running Windows or MacOS, and a Digital Link Interface system, available from E-Stim Systems. The software required to perform the update 'UpLink' is only available as part of the Digital Link Interface.
Where to Buy
Digital Link Pack (UK/ Europe)
Digital Link Pack (US / Rest of the World)
Or any good stockist of E-Stim Systems Products.
To switch the 2B into Bootloader Mode, remove ALL cables from the 2B, press and hold the Select switch and then turn your 2B on. The display should now show a 'B'. This is the bootloader mode.
