2.2
Antennas Interfaces
SMA female connectors
ANT
and
DIV
are intended to be used for connection of the cellular
antennas to the router.
The GNSS antenna’s SMA female connectors are shared with the
cellular connectors and can be connected to the
ANT3
for the L1 band and to the
ANT1
for
the L5 band. In addition, RP-SMA female connectors
WIFI1
are available for the connecting
the WiFi antennas.
Do not run the router without connected cellular antennas as the energy from the trans-
mission is effectively reflected by the open end and can damage the equipment.
Recommended tightening moment for screwing the antenna to the SMA connector is 0.9 Nm.

Ethernet Interfaces
The RJ45 panel socket is used for four ETH0 (switched) and one ETH1 Ethernet interfaces.
The pinout of the socket is shown in Figure
and described in Table

Table 4: Ethernet Connector Pinout Description of RJ45 Socket
All four ETH0 ports can be used for
PoE PSE
if the router is equipped with this feature. For
more information about the PoE, see Chapter
; for technical parameters, see Chapter
The isolation barrier of the Ethernet ports against the ground is 1500 V.
