Antenna Port Type
Table 4.2.: WLAN antenna port types
Attention: Following points must be observed when installing the antennas:
– A minimum clearance of at least 40 cm between people and the antennas must always
be ensured.
– If one WLAN inerface transmit simultaneously with other collocated radio transmitters
the separation distance of 20 cm between the antennas must be maintained at all
times.
– WLAN antennas must only be installed in buildings or within vehicle hulls.
– WLAN antennas may have an amplification of maximum 3dBi in the relevant frequency
range. WLAN antennas with a higher amplification may be used with the NetModule
router "Enhanced-RF-Configuration" software license and the antenna gain and cable
attenuation that have been correctly configured by certified specialized personnel.
4.4. Installation of the GNSS Antenna
The GNSS antenna must be mounted to the connector GNSS. Whether the antenna is an active or
passive GNSS antenna has to be configured in the software. We recommend active GNSS antennas
for highly accurate GNSS tracking.
Attention: Following points must be observed when installing the antenna:
– A minimum clearance of at least 40 cm between people and the antenna must always
be ensured.
– Antennas which are installed outside a building or the vehicle hull must limit transient
overvoltages (according to IEC 62368-1) to below a peak of 1500 V through external
protection circuits.
4.5. Installation of the Local Area Network
Up to two 10/100/1000 Mbps Ethernet devices can be directly connected to the router, further devices
can be attached via an addtional Ethernet switch. Please ensure that the connector has been plugged
in properly to ETH and remains in a fixed state, you might otherwise experience sporadical link loss
during operation. The Link/Act LED will lit up as soon as the device has synced. If not, it might be
necessary to configure a different link setting as described in chapter 5.3.2.By default, the router is
configured as a DHCP server and has the IP address 192.168.1.1.
