ib_temp (C)

iButton temperature measurement
(from iButton register page.)

ib_mission_start

Time when the mission starts (unix timestamp format).
(from iButton register page.)

ib_mission_samples_counte

(from iButton register page.)

ib_alarm_duration (minutes)

Alarm duration.
(from Alarm Timestamps page.)

ib_is_alarm_high (0,1)

0 : high alarm temperature;
1 : low alarm temperature.
(from Alarm Timestamps page.)

ib_hist_XXXX

Temperature histogram value.
XXXX is histogram binary address, from 0800 to 087C.
0800 corresponds to -38.5 and lower temperature
0802 corresponds to -38.0 .. -36.5
0804 corresponds to -36.0 .. -34.5
...
087A corresponds to +82.0 .. +83.

mileage (km)

hdop

HDOP

sat_mode

sat_fix

FS indicator:
0 – invalid
1 – Fix not available
2 – 2D Fix
3 – 3D Fix

is_fixnow

Sattelite Mode indicator 0 – no fix 1 – Autonomous GNSS Fix 2 – Differential GNSS Fix 3 – Estimated/Dead Reckoning Fix

ign (0,1)

Ignition

fake_ign (0,1)

“Fake Ignition” flag. If the device detects movement for at least 15 seconds or detects a point farther than MaxGuardDist, it raises this flag. If there is no movement for more than 15 seconds the device clears this flag.
