Figure 3 - Operating Mode Transitions
The above figure shows the relationship of the three primary operational modes and
how Asset-Link transitions from one mode to another.
2.4.2.3 Full-Power Mode
This is the full operational mode for the FCP. In this mode either the AMPS Cellular
Radio or the GSM module and the GPS receiver are powered on continuously. The
Asset-Link continuously monitors analog and digital I/O inputs, the power supply
voltage levels, and exceptions that have been enabled. The Asset-Link continuously
receives GPS position fixes and the AMPS Cellular Radio or GSM module is in a
standby mode waiting for a page.
If the communication via the AMPS Cellular Radio or GSM module is necessary, the
FCP will communicate the appropriate information via the appropriate radio.
When in Active mode, “Full-Power enabled” action can cause Asset-Link transition
to the Full-Power mode. While in Full-Power mode the device shall support all
routines and activities, as follows:
