2.2 Antenna

Connect cellular antenna to the router to main (ANT) SMA connector.
Only run the router with a cellular antenna connected to the main antenna connector, as
the energy from the transmission is effectively reflected by the open end and can damage
the equipment.
Recommended tightening moment for screwing the antenna to the SMA connectors is 0.9 Nm.

2.3 Ethernet Interfaces

The panel socket of RJ45 is used for Ethernet interface. The pinout of the socket is shown
in Figure 13 and described in Table 5.
