1. Overview
The 4G router series GXX-4GM consists of GXX-4GM and GXX-4GMPC subtypes for use with GMSplus and
a computer respectively. The GXX-4GM for use with GMSplus is conveniently installed in an IP66 protected
housing and provides in addition to the internal antennas an option for installing an external antenna. GXX-
4GM is supplied with all cables needed for installation with a GMSplus. GXX-4GMPC on the other hand is
delivered without any housing, but with necessary cables and connectivity.

Before proceeding, please make sure that:
- SIM card is not locked by a PIN code.
- the modem is NOT powered.
2.1. GXX-4GM
To access the SIM card slot on the GXX-4GM, remove the cover of the protective ABS housing of the router
and loosen the four screws holding the black modem (see red circles in Figure 3) and carefully lift and tilt the
modem until you see the SIM card slot.
Push in the SIM card completely to its full stop. There will be a small click sound.

Due to the small slot in the housing, a tool like a screwdriver might be required to fully push the
SIM card in.
3. Router Configuration
a
The router must be configured from a computer prior to use with the GMSplus.
Remove the cover of the protective ABS housing of the router and unplug the Ethernet cable. Plug in the
supplied standard Ethernet cable and connect the other end to the computer.
Power the router by connecting the power cable to the SERIAL connector of the GMSplus.
a
The GMSplus must already be configured to power the modem, as described in the GMSplus
manual
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 enter the IP 192.168.0.1 which is the
default IP address of the GXX-4GM series.
Log in with the username “admin” and password “admin”.
Under the “Carrier” section (see Figure 5), enter the “Access Point Name”, “User Name”and “Password”
provided by your GSM service provider. Make sure to configure any other parameters specifically given by
your provider, otherwise leave everything at default values.
Click “Submit” when done and leave the web interface by clicking “Logout”.
After a short while, before connecting the router to the GMSplus, we recommend checking that it is possible
to surf on the internet with the already connected computer. Therefore visit a couple of websites which are
known to be online, using the web browser on the computer. Those websites should be reachable before the
GMSplus can be connected to the router. In case of trouble check with your GSM service provider.

4. 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.

Figure 7. External antenna configured.
4.2. Preparation of the GMSplus
When used with the GXX-4GM series, the GMSplus requires no special hardware / jumper settings, but only
a certain configuration of operational settings.
Configure the GMSplus according to the GMSplus manual making sure that the Ethernet gateway will be the
GXX-4GM series and that the powering for the modem is done via GMSplus.
5. Electrical Connection
5.1. GXX-4GM
The GXX-4GM is supplied with all cables needed for use with GMSplus. Connect the two cables to the
Ethernet connector and the Serial connector of the GMSplus. The router will be both powered and have
communications with the GMSplus. Optionally an external antenna can be installed –see section 4.1.
