1-Wire Bus Interface 

The 1-Wire bus interface can be connected to sensors that support the 1-wire serial protocol 

such as Temperature sensors or driver identification. 

 

3.3V Power Out 

 

3.3V Power output is available to power peripheral sensors such a cargo sensor. The power is 

turned on only when the peripheral sensor is being read to save power. 

 

Input Voltage and Battery Voltage Monitor 

 

The Input Voltage monitorsand battery voltage monitor are internal analog inputs scaled such 

that the DC value of the voltage input pin to the PM-H system and internal battery voltage is 

measured. This value is scaled to span the most significant 8 bits of the A/D and consequently 

covers a scale from 0 to 32V for Input Voltage and 0 to 9V for internal battery voltage 

 

Timers 

 

Timers resident on the GSM baseband chip generate periodic interrupts for power down 

wakeup, watchdog support, report generation and other timer related functions. Report timers 

are supported by related AT command and cause generation of periodic reports. 

 

Watchdog 

 

MT6276 chipset provide internal software Watchdog, and a physically dedicate Watchdog 

circuit requirement is optional. 

 

Motion Detect 

 

Configurable through AT commands the unit can go to a low power mode when the main 

power is removed until motion is detected. Upon wakening, a report can then be generated, 

and the GPS enabled to detect drive events.
