Analog and Digital Input lines
The SmarTab 8 tablet provides seven automotive input lines (0-32V) through its enhanced cradle. The
input lines can be read as digital (state 0 or 1) or analog (voltage level) lines. Note, however, that the
automotive input 1/output 1 line is a part of the Standard Cradle Dev Cable.
Digital inputs
IGN (automotive voltage state) is for monitoring the ignition switch signal. The other seven input lines can
be used for any purpose, like sensing door opening, sensing bus amber lights, etc.
Note:
OS Burn using Fastboo t only works through the USB TYPE - C plug – not the cradle.
