1. Welcome to NetModule
Thank you for purchasing a NetModule product. This document should give you an introduction to the
device and its features. The following chapters describe any aspects of commissioning the device,
installation procedure and provide helpful information towards configuration and maintenance.
Please find further imformation such as sample SDK script or configuration samples in our wiki on
http://wiki.netmodule.com.

User Manual for NRSW version 4.5.0.100
2. Conformity
This chapter provides general information for putting the gateway into operation.
2.1. Safety Instructions
Please carefully observe all safety instructions in the manual that are marked with the symbol .
Compliance information: The NetModule gateways 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.
Information about the accessories / changes to the device:
– Please only use original accessories to prevent injuries and health risks.
– Changes made to the device or the use of non-authorized accessories will render the
warranty null and void and potentially invalidate the operating license.
Information about the device interfaces:
– All systems that are connected to the NetModule gateway interfaces must meet the
requirements for SELV (Safety Extra Low Voltage) systems.
– Interconnections must not leave the building nor penetrate the body shell of a vehicle.
– Connections for antennas may only exit the building or the vehicle hull if transient
overvoltages (according to IEC 62368-1) are limited by external protection circuits
down to 1 500 Vpeak. All other connections must remain within the building or the vehicle
hull.
– Always keep a distance of more than 40 cm from the antenna in order to reduce
exposure to electromagnetic fields below the legal limits.
– Devices with a WLAN interface may be operated only with applicable Regulatory Do-
main configured. Special attention must be paid to country, number of antennas and
the antenna gain (see also chapter 5.3.4). The maximum allowed gain is 3dBi in the
relevant frequency range. WLAN antennas with a higher amplification may be used
with the NetModule gateway "Enhanced-RF-Configuration" software license and the
antenna gain and cable attenuation that have been correctly configured by certified
specialized personnel. A misconfiguration will lead to loss of the approval.
– Cellular antennas attached to the gateway must have an antenna gain of equal or less
than 2.5 dBi. The user is responsible for the compliance with the legal regulations.
– Only CE-compliant power supplies with a current-limited SELV output voltage range
may be used with the NetModule gateways.

NG800
User Manual for NRSW version 4.5.0.100
General safety instructions:
– Observe the usage limitations of radio units at filling stations, in chemical plants, in
systems with explosives or potentially explosive locations.
– The devices may not be used in airplanes.
– Exercise particular caution near personal medical aids, such as pacemakers and hear-
ing aids.
– The NetModule gateways may also cause interference in the nearer distance of TV
sets, radio receivers and personal computers.
– Never perform work on the antenna system during a thunderstorm.
– Protect them against aggressive chemical atmospheres and humidity or temperatures
outside specifications.
– We highly recommended creating a copy of a working system configuration. It can be
easily applied to a newer software release afterwards.
2.2. Declaration of Conformity
NetModule hereby declares that under our own responsibility that the gateways
comply with the relevant standards following the provisions of the RED Directive
2014/53/EU. The signed version of the Declaration of Conformity can be obtained
from http://www.netmodule.com/downloads
2.3. Waste Disposal
In accordance with the requirements of the Council Directive 2012/19/EU regard-
ing 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.
2.4. 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.

The following table describes the NG800 status indicators.
Housing Label Software Label Color State Function
STAT SYS Shows the overall system state. This
could be derived from health indicators
such as:
– all services up and running
– overall throughput is normal
– CPU load is normal
– the supervisor
– . . .
– User application (state set by
user in SDK or container)
lg On System operation state: normal
lg Blinking System operation state: during startup
lr On System operation state: emergency,
watchdog, failure
LINK WAN lg On The hotlink connection is up.
lg Blinking The hotlink connection is established
or changing the interface.
mOff The hotlink is disabled.
Table 3.3.: NG800 Status Indicators
3.4.3. Reset
NG800 does not have a built-in reset button. An external reset can be triggered as described below
(e.g. by installing an external reset button). The reset button has two functions:
1. Reboot the system:
Apply reset signal for at least 3 seconds to release a system reboot.
The reboot is indicated with the blinking STAT LED.
2. Factory reset:
Apply reset signal for at least 10 seconds to release a factory reset.
The start of the factory reset is confirmed by all LEDs lighting up for a second.
The RS232 receive input (RS232-RXD, Pin L1 of X48 connector) also serves also reset input. To
assert a reset condition, the input is tied to a positive voltage >5.0 VDC. It is possible to connect to the
battery (12 VDC, 24 VDC).
When the input is asserted for longer than 100 micro-seconds (a character time) the receiver de-
tects a break condition which is treated as reset active indication. Further processing of the signal is
performed by software.

User Manual for NRSW version 4.5.0.100
When the serial interface is not used, a push button can be connected from the positive battery port to
the serial interface receive input (X48:L1) as shown in the following image.
Figure 3.1.: Reset Input (Serial Interface not used)
If the serial interface is used in the application, a break-before-make switch must be used. The switch
is required to protect the terminal equipment from the battery voltage.
In the inactive position the serial interface is connected between the terminal and the device, allowing
serial communication. In the active position, the terminal is disconnected, and the receiver input is
connected to the battery.
