–
the device is registered to the cellular network, it has an IP address, but
cannot login to the server
Possible reason: the primary and the secondary server is not available/accessable
Visible sympthoms:
•
the opening of the TCP/UDP port was not succesful (e.g. wrong server
settings applied),
•
unsuccesful data sending
•
timeout when tries to receive data or wrong answer
The signal will be active, until the device will be succesfully signaling to a server.
IN1, IN2: Input #1, #2 is active -
green
When the input is active (if the 2 pair wire closed; or in case of voltage the power voltage is 5-
24VDC) then the
INx LED
will light according to the related input.
OUT: Output is active
–
yellow
The output active indicator
OUT LED
shows the status of the primer-side of the relay. When the
output is active (the relay pair of wires are closed), then the output
OUT LED
will light.
MDM RDY: Modem stand-by
–
red
During the inicialization the
MDM LED
blinks quickly (approx. twice per seconds). When the
modem is already accessible and operating and has an active communication on the GSM
network, then it will flashing with less frequency.
Main important lights:
•
not lights:
the module was turned off
•
longer periodic flashing:
600 msec filling in / 600 msec filling out: the module not
registered to the network (possible causes: no SIM card, PIN authorization failure,
network search is in progress, login is in progress, etc.)
