1.1. Connection and Communication
Step 1:
Unscrew the front panel of the enclosure and remove the board from the
enclosure. The board should slide out easily without excessive force needing to
be applied.
Fig. 1.2 – SIM card holders
Slide open the primary SIM cardholder labelled “PRI” (see Fig. 1.2) and insert the
SIM card (ensure that the SIM card is not PIN protected). Lock the SIM card in
place once inserted.
Step 2:
Place the board on a non-conductive surface (e.g. A wooden table or a book).
Connect the 12V and ground terminals to a suitable power supply (at least
12V/1A). You should see the LED light up red and then flash green quickly,
indicating that power is connected and the unit is operating normally. After
approximately 10 seconds (network dependant) the LED should flash green
slowly (1 second intervals) indicating that the device has successfully established
communication with the cellular network.
