2.2 Antennas
Connect cellular antennas to the router to main (ANT) and diversity (DIV) SMA connectors
on the front panel. Connect WiFi antenna to the WiFi SMA connector on the side of the router.
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.
The diversity antenna improves the radio capability of the router at low signal strength.
2.3 Ethernet Interfaces
The maximum length of the cables connected to the Ethernet ports is 30 meters to meet
the EMC immunity conditions.
The panel socket of RJ45 is used for Ethernet interface. The pinout of the socket is shown
in Figure 15 and described in Table 4.
