(6) Operation time acquisition function
While the hour meter signal is ON (while the engine is in operation), the time is counted,
and the count value is integrated. Get the total operating time. Note that total operating
time is stored in nonvolatile memory.
(7) GPS information acquisition function
Acquisition of GPS information shall be made every 30 minutes (0 minutes, 30 minutes
per hour). After starting the device, the GPS module is started immediately.
When the GPS information can be positioned normally, the date and time of the GPS
information is reflected on the RTC of the apparatus. When the positioning fails,
the RTC is not updated. The time correction shall be implemented 24 hours after
the previous implementation times. Positioning satellites (NMEA sentences) shall be
GPS only (GLONASS is not used). GPS data is received (application acquires data)
At ｔｈe time of GPS positioning. However, when the application does not perform
positioning even after one minute has passed from the GPS information acquisition time
(start), the acquisition processing is ended as non-positioning.
(Surveyor system: WGS-84)

and to make the processing only fail-safe and not to occur frequently.
A) Reset by CPU's WDT time-up
b) Reset by CPU independent WDT time up
C) Restart by software at system error
d) Regular Reset of Communication Module
(11) Serial communication function with personal computer
Communicate with the personal computer using RS232C 1ch.
(12) Display (LED) function
a) When the engine is on and it is within range, blinking at a slow cycle
(1000ms on / 1000ms off)
b) When the hour meter signal is ON, and when it is out of service area,
it blinks earlier (200ms on / 200 m turn off)
c) It turns off when the hour meter signals OFF or when the battery on the
construction machine side is not connected (when the built-in battery is operating)
(13) Date and time setting function
