Template:FMM640 Advanced Trip Settings
Advanced Trip Settings[edit source]
Remember iButton functionality. If Remember iButton and Trip parameters are enabled, ignition is on and iButton is attached then FMM640 remembers iButton ID. iButton ID is saved and sent to the server with every record. If new iButton is attached during the Trip, FMM640 remembers new iButton ID. FMM640 forgets iButton ID after ignition is off and ignition timeout is reached.
