The DWM-321D/DWM-321 requires at least two of the four external antennas
to function correctly. The included antennas are interchangeable.
1. Attach the LTE antennas to the ports labelled CELL1 Main and
CELL1 Aux. Turn clockwise to fasten the antenna.
(Optional*)
To utilize CELL2, attach the two remaining
LTE antenna’s to CELL2 Main and CELL2 AUX.
(Optional)
To utilize the Wi-Fi function, attach the two
Wi-Fi antenna’s to 2.4G/5G WIFI ports.
(Optional)
To utilize the GNSS function, attach a third
party antenna to the GNSS port.
