ALARM report
Alarm report(s) is also configurable. User can customize the events generated by the in-vehicle input to be sent
to the server. To enable the particular trigger reports by click the box.
Sleep mode (when ACC OFF)
(1) HEU can go to sleep mode when ACC goes off. (The average lasting time after ACC OFF is 5 minutes.) In
sleep mode, both GPS & GPRS will be disabled.
All the auto report (Time, Distance, Intelligent…) will not be send when ACC goes off.
(2) During the sleep mode, the system can wait up automatically and send a wake up diagnostic report.
(3) The automatic wakeup time is configurable. (Minimum duration is 5 minutes; maximum duration is 1000
Hours).
(4) If any of the inputs are triggered while in the sleep mode, the system will wake up automatic report and then
send reports to the server. The input triggers for waking the device up are selectable. If the GPRS connection is
failed, for emergency purpose, HEU will send out SMS report if number is defined.
[Button description]
(1)Initialize: clear all saved parameters in HEU.
(2) Request All: request all parameters that is saved previously in HEU
(3) Request: request parameters in the current page
(4) Apply: set the parameters in the current page
(5) Apply All: save all the parameters into HEU
(6) Load: load the saved configuration file (*.heu)
(7) Save: save the parameters into a files (*.heu).
(8) Exit: exit the PC-Setup program; the system will exit the PC setup mode into the working mode.
INTERNAL BATTERY PROTECT MECHANISM:
To protect internal battery, we added a mechanism to HEU, when the internal battery voltage drop to 9v,HEU will keep to
detect battery voltage for 2 minutes, if the battery voltage keep 9v continuously during this 2 minutes period. HEU will
send a “battery shut down event” to server to notice user. After this event is sending out, HEU only can work another 30
minutes.
After HEU goes into “battery shut down” mode, HEU will check the battery continuously, if the battery charges to 12v
for 2 hours, it can work again.
