NB1600 User Manual

4.4. Installation of the GSM/UMTS Antenna

NetModule routers will only operate efficiently in the cellular network if there is a good
signal. The stub antenna will be suitable for most applications. However, in some
circumstances it might be necessary to use remote antennas together with an extended
cable to reach a better location offering an adequate signal. In doubt, please contact us
and we would be pleased to assist you in figuring out the best matching antenna setup
for your application.
Keep in mind that effects caused by Faraday cages such as large metal surfaces (elevators,
machine housings, etc.), close meshed iron constructions and others may reduce signal
reception significantly.
The antenna or antenna cable has to be mounted to the Mobile 1 connector and should
be fixed with a wrench.

4.5. Installation of the WLAN Antennas

Any WLAN antennas must be mounted to the connectors WLAN1 and WLAN2 . The
number of attached antennas can be configured in the software. If only one antenna is
used, it must be attached to WLAN1 . However, for better diversity and thus better
throughput and coverage, we highly recommend using two antennas.

4.6. Installation of the Local Area Network

Up to two 10/100 Mbps Ethernet devices can be directly connected to the router, fur-
ther 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 other-
wise 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.

4.7. Installation of the Power Supply

The router can be powered with an external source supplying between 12 V and 48 V .
DC DC
It is to be used with a certified (CE or equivalent) power supply, which must have a
limited and SELV circuit output. The router is now ready for getting engaged.
