ARK-1388V User Manual 48
All the in-vehicle installed systems require a sophisticated power management. The
new Advantech solution based on the Box IPC ARK-1388V designed especially for
in-vehicle applications offers due to its outstanding hardware and firmware design in
microcontroller based safe boot and safe shut down functions. The rugged industrial
PC works with both 12 volt and 24 volt battery systems. The innovative power man-
agement system is dedicated primarily for taxicabs, trucks, wagons, mining, and city
buses. This chapter will introduce how to setting the relative parameter of the power
management system.
4.1 Power mode selection
ARK-1388V can work as a normal Box IPC or in-vehicle Box IPC. But the power solu-
tion of these two applications is quite different. The connector CN18 is designed for
selecting whether the power input is in-vehicle power or not. If the two pins of CN18
are leaved open without any jumper on it, then ARK-1388V will work as an in-vehicle
Box IPC. Its power management firmware design in PIC microcontroller will start to
work.
