Router Configuration

Power the router by connecting the power cable to the SERIAL connector of the GMSplus.
The GMSplus must already be configured to power the modem, as described in the GMSplus manual

Before connecting the router to the GMSplus, we recommend checking that it is possible to surf on the internet. with the already connected computer. The GXX-4GM series router acts as a DHCP server and therefore no fixed IP must be set in the computer. As soon as the connection is established ( ), open a web browser and visit a couple of websites which are known to be online, using the web browser on the computer.
If the websites are not accessible, you may need to set APN settings manually (check with your GSM service provider for the correct settings). Open a web browser and enter the IP 192.168.168.1 which is the default IP address of the GXX-4GM series.
Log in with the username “admin” and password “123456”.
The APN settings can be entered under “Carrier” -> “Settings”

Hardware Configuration

4.1. Internal / External Antenna
The GXX-4GM router can be used with the internal antenna (default) or with an external cable/antenna in case the cellular reception on the measurement site is weak. To use the external antenna connector, first unscrew the SMA antenna which is labelled “ANTENNA” on the modem. The SMA connector for the external antenna connector can now be unscrewed from its place holder and connected to the modem. The SMA antenna can be mounted on the SMA place holder not to lose it.
