Buzzer: It is disabled automatically after being released from
jamming.
Device will send an alert after recovering the GSM network.
It takes about 2 minutes or more for the device to complete a
jamming detection.
Default : 0
JAM_CHK_DIST
‘0’ ~’60000’
Meter
This is complementary to the detection function of device
described above on the GPRS jamming by utilizing a
distance value as a parameter when jamming is done.
Once jamming on the GPRS network starts being detected,
the device will also check the distance between the current
location of the vehicle and the First geographical Point (
‘Fp’)
where the jamming started being detected.
If the distance is greater than JAM_CHK_DIST for a while
triggered by JAM_DET mode.
If
‘0’, skip this procedure.
Default : 500 meters
JAM_CHK_TM
‘0’ ~ ‘43200’
Sec.
It is complementary to the function of GPRS jamming
detection in an area
‘without GPS connectivity’ (‘No GPS’).
After detecting jamming first in such a bad GPS connecting
area, the device begins to count the 2 time-length factors (
A
and B
) to make a sum (
A + B = C
) if the vehicle moves in the
area:
A: time length that needs to complete the
jamming detection
B: time length that the vehicle driver needs to
complete driving in the area.
If
C
(the sum) is longer than the length of the jamming
detection (
‘JAM_CHK_TM’) the device judges that jamming
was done in the area. Please refer to the table for more
details.
If the has not moved in the area, ignore jamming detection
until the jamming detection function is released.
If
‘0’, skip this procedure.
Default: 300 seconds.
VI_ON_THRES
String
1/255G
Threshold value for Motion Virtual Ignition On
Range : 3~30
Default : 5
VI_ON_DELAY
String
Sec.
Delay time for Motion Virtual Ignition On
Range : 3~999
Default : 10
VI_ON_PERCENT
String
%
Percent for Motion Virtual Ignition On.
