Data reports consist of a single record that contains all location data and system status. The device comes pre-configured and ready to use from the factory. The PM-L appears to a user or a server application as a single endpoint device. It can be queried, updated and configured either through a serial connection, or an over the air LTE or WCDMA IP connection, or through SMS messaging.
The Input Voltage monitors and battery voltage monitor are internal analog inputs scaled such that the DC value of the voltage input pin to the PM-L system and internal battery voltage is measured. This value is scaled to span the most significant 8 bits of the A/D and consequently...
The PM-L supports OTA field upgrades of the resident application. An over the air TFTP (Trivial File Transfer Protocol) connection is made over an IP connection. A replacement file is then transferred from a server to the PM-L and that file replaces the previous application image.
Any hardware or software reset will return the device to full power mode. 3.5 Report The PM-L captures data and forms a report record with that data. A report is a data structure containing all of the sensory and other typically useful data on the device. Reports are generated in response to specified events, such as periodic timeout, speed threshold, geo-fence crossing, etc., or in response to a Report Now command.
