Battery Isolator
The battery isolator jumper must be connected so as the database (users, iFobs, events etc) can be retained in RAM
(random access memory) upon removal of operating system power.
Memory
The 16 bit Control PCB hardware includes:
512K Words of Flash Program Memory (that's 1M bytes or 8M bits)
8M Words of SD-RAM Data Memory (that's 16M bytes or 128M bits)
We can increase the size of the Flash and SD-RAM in the future simply by fitting bigger memory chips. This does mean
replacing the Control PCB but the reason for fitting smaller memory values at the moment is to keep the cost down.
Status LED's: The new hardware includes 2 status LED's to show Power Status and Processor status.
Control PCB Serial Number (CPSN): The new Control PCB will have an electronic serial number. This will allow us to
track what Control PCB's are fitted to what system. This will also be used as security for enabling the cost options that
are available such as Mileage Logging, Key Booking etc.
