1 Conformity
This chapter provides general information for putting the router into operation.
1.1 Safety Instructions
NetModule routers must be used in compliance with any and all applicable national and
international laws and with any special restrictions regulating the utilization of the communication module in prescribed applications and environments.
We would like to point out that only the original accessories, shipping with the router, must
be used in order to prevent possible injury to health or damage to appliances and to ensure
that all the relevant provisions have been complied with. Unauthorized modifications or utilization of unapproved accessories may void the warranty. The routers must not be opened.
However, it is possible to replace any pluggable SIM cards even during operation.
All circuits connected to the interfaces of the router must comply with the requirements of
Safety Extra Low Voltage (SELV) circuits and have to be designed for indoor use only. Interconnections must not leave the building nor penetrate the body shell of a vehicle. Possible
antenna circuits must be limited to over-voltage transient levels below 1 500 VDC (according
to IEC 62368-1, TNV-1 circuit levels) by using safety approved components.
HotSpot routers shall only be used with a certified (CE or equivalent) power supply which
must have a power limited and SELV circuit1output.
They are basically designed for indoor use. Do not expose the communication module to
extreme ambient conditions and protect the communication module against dust, moisture
and high temperature.
We remind the user of the duty to observe the restrictions concerning the utilization of radio
devices at petrol stations, in chemical facilities or in the course of blasting works in which
explosives are used. Switch off the communication module when traveling by plane.
You need to pay increased attention when using the communication module close to personal medical devices, such as cardiac pacemakers or hearing aids. NetModule routers may
also cause interference in the nearer distance of TV sets, radio receivers and personal computers.
Avoid any installation of the antenna during a lightning. Always keep a distance of more
than 40 cm from the antenna in order to reduce exposure to electromagnetic fields below
the legal limits. This distance applies to
λ
4
- and
λ
2
-antennas. Larger distances may apply to
antennas with higher gain.
Any Ethernet cabling must be shielded, the Ethernet section of this manual provides more
information.
Devices with a WLAN interface may be operated only with applicable Regulatory Domain
configured. Special attention must be paid to country, number of antennas and the antenna
gain. A misconfiguration will lead to loss of the approval.
Cellular antennas attached to the router must have an antenna gain of equal or less than 2.5
dBi. If an extension cable is used to attach the antenna, the antenna gain may be higher by

Note: Power supplies for routers with the Pb option (72-110 VDC) cannot be a SELV circuit, since the voltage is
greater than 60 VDC.

the amount of cable attenuation. The user is responsible for the compliance with the legal
regulations.
We highly recommended creating a copy of a working system configuration. It can be downloaded using the Web Manager and easily applied to a newer software release afterwards as
we generally guarantee backward compatibility.
1.2 Declaration of Conformity
NetModule hereby declares that under our own responsibility that the
routers comply with the relevant standards following the provisions of
the RED Directive 2014/53/EU. The signed version of the Declarations of
Conformity can be found on the NetModule web page.
1.3 Waste Disposal
In accordance with the requirements of the Council Directive 2002/96/EC
regarding Waste Electrical and Electronic Equipment (WEEE), you are
urged to ensure that this product will be segregated from other waste
at end-of-life and delivered to the WEEE collection system in your country
for proper recycling.
1.4 National Restrictions
This product may be generally used in all EU countries (and other countries following the
RED Directive 2014/53/EU) without any limitation. Please refer to our WLAN Regulatory
Database for getting further national radio interface regulations and requirements for a
particular country.

HOTSPOT Manual, Version 1.1
4.2 Advanced Settings
Two operational modes are available. The terms-only service (ToS) mode shows a Terms of
Service page and the user has to accept these terms before getting access to the Internet.
The second mode is for using an RADIUS configuration, which requires an external RADIUS
server. In this mode the user is getting an captive portal web page with user login and
password field before he can reach the Internet.
4.2.1 ToS
Figure 4.2: ToS
Parameter
Bandwidth Limitation This option limits the bandwidth (up and download) of each
user/device which is connected and authenticated to the
Hotspot interface. This option is available with ToS only.
Traffic Limitation With this option it is possible to limit the data consumption
per user/client. After reaching the given traffic limitation the
user/client will be redirected to the login page again. This option is available. with ToS only.
11
HOTSPOT Manual, Version 1.1
Parameter
Inactivity Timeout If a station does not send anything within this timeout the user
will be automatically logged out. This option is available with
ToS only.
Access local interfaces If selected, the user can reach services which are connected
on a local interface of the router
4.2.2 RADIUS
Figure 4.3: RADIUS
Parameter
RADIUS Server The IP address of the radius server. This option is available
with RADIUS configuration only
Shared Secret This option defines the shared secret of the radius server (RA-
DIUS configuration only)
Authentication Port The authentication port of the radius server. This option is
available with radius only.
Accounting Port The authentication port of the radius server. This option is
available with radius only.
12
HOTSPOT Manual, Version 1.1
Parameter
Accounting Interval This interval specifies in which seconds the Hotspot process
will report accounting information to the radius server. This
option is available with radius only.
Account external traffic
only
If enabled the Hotspot process will report external traffic only.
This means the internal traffic like Walled Garden traffic will
be ignored. This option is available with radius only.
Access local interfaces If selected, the user can reach services which are connected
on a local interface of the router
4.3 UAM
With the Universal Access Method (UAM) settings it is possible to configure external services
for hotspot e.g. external custom landing page.
Figure 4.4: UAM
Parameter
External UAM Server The URL of the web server for client authentication
13
HOTSPOT Manual, Version 1.1
Parameter
UAM Port If an unauthenticated client tries to access the internet the
client will be redirected to this port of the local IP address of
the router
External UAM Homepage The URL of the homepage where unauthenticated clients were
redirected
UAM Secret The shared secret between external UAM server and hotspot
process.
Note: If not using an external UAM server or UAM hompage, leave the configuration param-
eter empty to use the default values.
4.4 Walled Garden
Figure 4.5: HotSpot Feature Walled Garden
With the Walled Garden settings it is possible to offer free services like web pages to the
customer/user without having an account or without accepting the ToS agreements. The
services which are configured via an URL and a description will be ignored by the captive
portal and the user will reach the services directly.
