Slide bracket to the rightThe DFNEXT observatories usually ship without modems as many of them are deployed with WiFi or Ethernet connectivity and different areas of the world require different modems.
If you wish to network your DFNEXT observatory via mobile broadband instead of WiFi or Ethernet you need to source a modem and request a modem installation care package from DFN Camera Help.
The recommended modems are the Sierra Wireless AirPrime MC Series MC7455 (for the Americas, Europe, the Middle East and Africa) and the MC7430 (for Asia Pacific including Australia).
Installation Steps
Once you have the modem, installation care package (containing the modem adaptor board, USB cable, modem bracket and screws) and a SIM card, you can install the modem by following the steps bellow.
Connect the modem USB cable to the modem.
Insert the modem into the adaptor board.
Press modem down and fasten with the two small screws.
Take the modem bracket and two large screws.
Fasten the modem bracket using the two large screws and the threaded holes below the PCB.
Ensure the bracket is installed as far to the right as possible to allow the connector to clear the PCB standoff above the modem bracket.
Use a hot air gun to bend the USB cable out of the way of the modem.
Lift one side of the PCB to clear the modem's USB connector which should face upwards.
Firmly slide the modem into the bracket ensuring it reaches the bottom. (The slots in the bracket may require some filing.)
Attach the short GSM antenna pigtail to the main antenna port on the modem using your fingers or some needle-nose pliers.
Ensure the U.FL connector is seated correctly.
Tuck the excess USB cable under the PCB and connect the USB connector to the PC.
