Charging Mechanism
The Micronet SmarTab 8 provides a smart charging mechanism. When connected to a power source
(e.g., wall mount power supply, PC USB, SmarTab 8 cradle), the battery is charged and powers the CPU
in parallel. On reaching temperatures above 45°C, the internal battery turns off charging from the
power source (current is limited to only draw 10uA). After interrupting charging, the power source from
the SmarTab 8 battery reconnects and provides power to the CPU. This mechanism prolongs the life of
the battery.
Charging Temperature
The Micronet SmarTab 8 battery charging temperature is as follows:
•
Charge: 0°C to ~ +45°C, 45~85% RH
•
Battery operating temperature: 0°C to ~ +45°C, 45~85% RH
NOTE:
The operating system blocks charging when the battery temperature is over the
defined (45°C). By this function, the device is protected while in operation.
Motion Control
The Micronet SmarTab 8 tablet provides an accelerometer, compass, and gyroscope module. The
accelerometer is an electromechanical device used to measure acceleration forces. Such forces may be
static like the continuous force of gravity or as is the case with many mobile devices dynamic to sense
movement or vibrations.
Communication Interfaces
Serial Communication
The Micronet SmarTab 8 tablet provides serial communication ports through the cradle.
The standard cradle model includes one serial port, and the enhanced cradle model includes five serial
communication ports. Please refer to the detailed description of the standard cradle
