4.4. Installation of the GPS Antenna
The GNSS antenna must be mounted to the connector GPS . Whether the antenna is an active or
passive GPS antenna has to be configured in the software. We recommend active GPS antennas for
highly accurate GPS 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 six 10/100 Mbps and 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 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 .
4.6. Installation of the Power Supply
The router can be powered with an external source supplying between 12 V
DC
and 48 V
DC
. It is to be
used with a certified (CE or equivalent) power supply, which must have a limited and SELV circuit out-
put. The router is now ready for getting engaged.
Attention: Only CE-compliant power supplies with a current-limited SELV output voltage
range may be used with the NetModule routers
