8.4. Power Subsystem
8.4.1. Overview
The Power Subsystem APIs can be used to get and set the configuration of
power subsystem. By invoking the Power Subsystem APIs, the users can:
1. Get the firmware version number of the Power Subsystem.
2. Set all the settings of the Power Subsystem to the default values.
3. Get/Set the status of the remote switch(ENABLE or DISABLE).
4. Get the battery voltage.
5. Get/set the status of the battery monitor (ON or OFF).
6. Get/set the delta value which identifies how much the battery voltage can be
lower than the nominal voltage. When the voltage is lower than the tolerable
voltage, the power subsystem turns off the system.
7. Get/set the Soft Off delay.
8. Get/set the Hard Off delay.
9. Get/set the Power On delay.
10. Get/set the Shutdown delay.
The power subsystem connects to the main system via the COM port. On the
Linux platform, the actual port number to which the Power Subsystem
connects is determined by the Linux. The default supported COM interfaces
on Linux are COM1~COM4. Users must take extra steps to configure Linux
kernel in order to support COM ports which do not fall into the range COM1 ~
COM4. Please refer to Appendix A for more information. Users don’t need
extraordinary setup on Windows platform to support COM ports.
