Cellular transmission stops
Symptom
:
Counter stops transmitting despite good cellular signal
strength.
1.
Cause:
Extremely low battery. To protect the counter from damage,
the electronics, fan and CO
2
are automatically shut down. To
view the battery voltage range during the last 24 h, go to
Dashboard -> Location table
and scroll the horizontal bar
until you see the column “Voltage Range”.
Note
: A 12 V battery is considered 0 % charged when the
voltage is below 11.8 V, and fully charged, when voltage is
above 12.8 V.
Solution
: Replace or charge battery.
2.
Cause
:
Counter needs reset.
Solution
:
•
Disconnect power
•
Wait 30 seconds
•
Reconnect power
•
Insert hand into the funnel to block the sensor
•
Wait 4 beeps that indicate power (4 beeps if battery is
fully charged)
•
After 15-90 seconds, verify cellular signal strength beeps
(1-5 long beeps, corresponding to 1-5 signal bars); if the-
re
are only two short beeps, there is no cellular connec
-
ti
vity
•
Right after the cellular signal indication, there will be 5
additional short beeps followed by a long beep.
•
Power-cycle the counter once more
•
After 30 minutes, go to the website and verify if new
transmissions have been recorded.
Cellular signal & Transmission
Checking cellular connectivity
If the counter is in a location with weak cellular signal, the
cellular data connection to the server may be unreliable.
The signal strength at the deployment site can be checked
as follows:
Connect counter to power, then pay attention to beeps:
1.)
Immediately
: One to four beeps indicate battery voltage:
•
4 beeps: fully charged
•
3 beeps: partially charged
•
2 beeps or 1 beep: discharged, counter and trap will not
run
2.)
After 10-90 seconds
, check for 1-5 long beeps that indi-
cate cellular signal strength (like the bars on a cell pho-
ne):
•
3-5 beeps: strong signal
•
2 beeps: marginal signal
•
1 beep: weak signal
•
2 short beeps: no connection
Cellular signal too low
Symptom:
Two short beeps about 1-2 minutes after connecting the trap
to power.
Cause:
Weak or no cellular reception at the present location.
Solutions:
•
Move trap to a location which has stronger reception.
•
Continue using the trap: data will be saved and uploaded
upon the next time there is reception.
Irregular transmission times
Symptom
:
Trap doesn’t transmit data when scheduled.
Cause
:
Weak cellular connection or cellular network is busy.
Solution
:
See “Cellular signal is too low”.
