    Default Upgrading Nntn7585 APX dual charger firmware

    I've got a dual charger I need to update firmware on. Is this accomplished via the normal Impres field upgrade unit or do you somehow use the USB port on the back of the charger? Also, if it's not through the USB port, what is that port used for?

    Thanks !
    What?!? Hiring a guy who USES the equipment daily to FIX the equipment? You mean, instead of a college preppie who only knows the theory behind how it is SUPPOSED to be used? Woah, what a novel idea!

    What's the latest version? I've got a brand new v1.05 unit that I've never used.

    I came across this section in the User Guide document for the NNTN75[8-9]x series Dual-Unit chargers which seems to positively confirm the original question of whether or not you use the Mini-USB port for software/firmware:

    Anyone know what the latest version is? is there anything beyond 1.05 and, if so, any release notes?

    I'm floored they actually used a standard, common and cheap off the shelf connector instead of some newly created $500.00 Motorola proprietary connector. The design team must be slipping.

    Now off to find at least 1.05 firmware. I have a pile of NOS impress batteries that refuse to charge because they are at zero volts.. so frustrating!
