• Check that voltage and power available at installation is within range specied for modem. It can be
found on this guide and labelled on gateway.
• Do not install any gateway that is obviously damaged or suspected of having been damaged.
• In order to provide strain relief and to avoid transmitting excessive vibration to the device during
installation, all cables connected to EasyTunnel must be secured or clamped immediately adjacent
to the device’s connectors.
• To protect the power supply cables, and in order to comply with the re safety requirements, when
the unit is powered from a battery or a high current supply, a fast 1.25A fuse should be connected in
line with the positive supply.
• No compatible component or product must not be connected to EasyTunnel.
• Note! EasyTunnel distributors and sales ofces may refuse warranty claims where evidence of product
misuse is found.
1.2 Safety requirements and protection regulations
PLEASE READ THESE SAFETY INSTRUCTIONS AND KEEP A COPY OF THEM
• EasyTunnel, for any type of operation, is only accessible for instructed and skilled installers, testers
and technical engineers.
• Before any type of handling of EasyTunnel, it must be ensured that it has been de-energized to allow
for electrical work to be carried out and it cannot be inadvertently re-energized.
• Always ensure that use of EasyTunnel is permitted. The modem may present a hazard if used in
proximity to personal electronic medical devices. As a rule, the modem must not be used in hospitals,
airports or planes.
• This equipment is not suitable for use in locations where children are likely to be present.
• Never use the device at a gas station, refuelling point, blasting area or in any other environment
where explosives may be present.
• Operating the device close to other electronic devices, such as antennas, television sets, and radios
may cause electromagnetic interference.
• This product is intended to be used with the antenna or other radiating element at least 20cm away
from any part of the human body. In applications where this rule cannot be applied, the application
designer is responsible for providing the SAR measurement test report and declaration.
• You are responsible for observing your country’s safety standards, and where applicable, the relevant
wiring rules.

1.3 SIM Card Precautions
Before handling the SIM card in your application, ensure that you are not charged with static electricity.
Use proper precautions to avoid electrostatic discharges.
• When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card holder.
• Caution! Do not touch these connectors! If you do, you may release an electrical discharge that could
damage the modem or the SIM card.
• When designing your application, the SIM card’s accessibility should be taken into account. We
always recommend that you have the SIM card protected by a PIN code. This will ensure that the SIM
card cannot be used by an unauthorized person.
1.4 Antenna Precautions
If the antenna is to be mounted outside the device, consider the risk of lightning. Follow the instructions
provided by the antenna manufacturer. Never connect more than one modem to a single antenna. The
modem can be damaged by radio frequency energy from the transmitter of another modem.
• Like any mobile station, the antenna of the gateway emits radio frequency energy. To avoid EMI
(electromagnetic interference), you must determine whether the application itself, or equipment in
the application’s proximity, needs further protection against radio emission and the disturbances it
might cause. Protection is secured either by shielding the surrounding electronics or by moving the
antenna away from the electronics and the external signal cable.
• The gateway and antenna may be damaged if either of them comes into contact with ground potentials
other than the one in your application. Beware: ground potentials are not always what they appear
to be.
1.5 Radio Frequency (RF) Exposure and SAR
Your wireless device is a low-power radio transmitter and receiver (transceiver). When it is turned on, it
emits low levels of radio frequency energy (also known as radio waves or radio frequency elds).
Governments around the world have adopted comprehensive international safety guidelines, developed by
scientic organizations such as ICNIRP (International Commission on Non-Ionizing Radiation Protection)
and IEEE (The Institute of Electrical and Electronics Engineers Inc.), through periodic and thorough
evaluation of scientic studies. These guidelines establish permitted levels of radio wave exposure for
the general population. The levels include a safety margin designed to assure the safety of all persons,
regardless of age and health, and to account for any variations in measurements. Specic Absorption
Rate (SAR) is the unit of measurement for the amount of radio frequency energy absorbed by the body
when using a transceiver. The SAR value is determined at the highest certied power level in laboratory
conditions, but the actual SAR level of the transceiver while operating can be well below this value. This
is because the transceiver is designed to use the minimum power required to reach the network.
EasyTunnel device has been approved for applications where the antenna is located more than 20cm
from the body of the user. In all other congurations the user is responsible for meeting the local SAR
regulations.
Users of the EasyTunnel gateway are responsible for ensuring that they meet the SAR regulatory
requirements of the countries in which they intend to operate the device and that their documentation

contains the relevant SAR declaration, certication information and user guidance as appropriate.
1.6 SAR information
Wireless Modules models: EC21 is marketed without a dened antenna.
The Maximum Antenna Gain when using indoor antennas depends on the distance from the antenna to
any nearby persons when in normal operation. It should not exceed the values shown on the table below.
According to the limit in 47 CFR 1.1310, we get the value of the maximum antenna gain as follows:
The maximum measured power output in the 900 MHz band is 1995.26 mW (33 dBm).
The maximum permissible exposure dened by 47 CFR 1.1310 is f/1500 = 0.6 mW/cm².
The maximum measured power output in the 1800 MHz band is 1000 mW (30 dBm).
The maximum permissible exposure is dened as 47 CFR 1.1310 with 1 mW/cm².
According to the limit in 47 CFR 1.1310, we get the value of the maximum antenna gain as follows:
S = P*G/4πR²; G = 4πR² (S / P)
S = 0.6 mW/cm² or 1 mW/cm²
P = 1995.26 mW or 1000 mW
R = 20 cm or 50cm
π = 3.1416
G(dBi)=10*log(G)
Solving for G; the maximum antenna gain is:
BAND P (mW/ dBm) S ( mW/ cm²) DISTANCE MAX.GAIN (dBi)
900MHz 1995.26 / 33 0.6 20cm 1.79
900MHz 1995.26 / 33 0.6 50cm 9.75
1800MHz 1000 / 30 1 20cm 4.79
1800MHz 1000 / 30 1 50cm 14.97
1.7 Personal Medical Devices
Wireless devices may affect the operation of cardiac pacemakers, hearing aids and certain other
implanted equipment. If a minimum distance of 15 cm (6 inches) is maintained between the EasyTunnel
device radiating antenna and a pacemaker, the risk of interference is limited. If the user’s application is
likely to be situated in the vicinity of personnel, a suitable warning should be contained in the equipment
manual to this effect.

1.8 SAR Requirements Specic to Portable Mobiles
Mobile phones, PDAs or other portable transmitters and receivers incorporating a GSM module must
be in accordance with the guidelines for human exposure to radio frequency energy. This requires the
Specic Absorption Rate (SAR) of portable EC21 based applications to be evaluated and approved for
compliance with national and/or international regulations.
Since the SAR value varies signicantly with the individual product design, manufacturers are advised
to submit their product for approval if designed for portable use. For European markets the relevant
directives are mentioned below. It is the responsibility of the manufacturer of the nal product to verify,
whether further standards recommendations or directives are in force outside these areas.
Products intended for sale in US markets
EN 50360: Product standard to demonstrate the compliance of mobile phones with the basic restrictions
related to human exposure to electromagnetic elds (300MHz – 3GHz)
Please note that SAR requirements are specic only for portable devices and not for mobile devices as
dened below:
• Portable device: A portable device is dened as a transmitting device designed to be used so that the
radiating structure(s) of the device is/are within 20cm to the user’s body.
• Mobile device: A mobile device is dened as a transmitting device designed to be used in other than
xed locations and to generally be used in such a way that a separation distance of at least 20cm is
normally maintained between the transmitter’s radiating structure(s) and the user’s body or that of
nearby persons. In this context, the term “xed location” means that the device is physically secured
at one location and cannot be easily moved to another location

2 I0 DI Digital input #0
3 D+ IO RS485 positive line
4 D- IO RS485 negative line
5 + PWR Positive power supply input
6 - PWR Negative power supply input
Power supply input is externally connected on terminal block, positive signal at pin 5 and negative signal
at pin 6. Operating range values are specied at (table 2.2).
EasyTunnel gateway is equipped with a RS485 half-duplex interface with external connection on terminal
block type connector. D+ signal has to be connected on pin 3 and D- signal on pin 4.
Formerly, TIA/EIA-RS485 specication identies A signal as equivalent to D- and B signal as equivalent
to D+, nonetheless, some semiconductor manufacturers adopted the opposite relationship, so it is
recommended to follow D+ and D- signal identication.
RS485 interface features ESD protection with internal network termination resistor and fail-safe
polarization network.
A general-purpose digital input is included within EasyTunnel gateway, available on the terminal block
type connector on pin 2.
To activate any input externally, it must be shorted to V- input on pin 6 of terminal block so it is recommended
to use external dry-contact type devices, as relays or open-drain/collector transistors.
Finally, a general-purpose digital output is included within EasyTunnel gateway in this terminal block.
Operating range values are specied at (table 2.2).
2.9 Antenna Connection
EasyTunnel device provides SMA female connector to attach external antenna. This connector allows
radio frequency (RF) transmission signals between the modem and an external customer-supplied
antenna. EasyTunnel is tted with a 50Ω SMA female coaxial connector.
These external antennas must be matched properly to achieve the best performance regarding radiated
power, DC-power consumption, modulation accuracy and harmonic suppression.

Consider the following requirements:
• The antenna must be designed for one of the frequency bands in use; please ask your network
provider for more information.
• Frequency according to band of chosen 4G module
• The impedance of the antenna and antenna cable must be 50Ω
• Antenna connector should be SMA-M type
• Antenna power should be at least 500mW as maximum power is 316.23mW.
• Maximum Output RF load mismatch ruggedness at antenna is 10:1 VSWR
The antenna should be placed away from electronic devices and other antennas. The recommended
minimum distance between adjacent antennas, operating in a similar radio frequency band, is at least
50cm. If the signal strength is weak, it is useful to face a directional antenna towards the closest radio
base station. This can increase the strength of the signal received by the modem. The LoRa module’s
peak output power can reach 320mW.
RF eld strength varies with antenna type and distance. At 10cm from the antenna the eld strength may
be up to 70V/m and at 1m it will have reduced to 7V/m. In general, CE-marked products for residential /
commercial areas and the light industry can withstand a minimum of 3V/m.

Possible communication disturbances include the following:
• Noise can be caused by electronic devices and radio transmitters
• Path-loss occurs as the strength of the received signal steadily decreases in proportion to the distance
from the transmitter.
• Shadowing is a form of environmental attenuation of radio signals caused by hills, buildings, trees or
even vehicles. This can be a particular problem inside buildings, especially if the walls are thick and
reinforced.
• Multi-path fading is a sudden decrease or increase in the signal strength. This is the result of
interference which is caused when direct and reected signals reach the antenna simultaneously.
Surfaces such as buildings, streets, vehicles, etc., can reect signals.
• Hand-over occurs as you move from one cell to another in the GSM network. Your mobile application
call is transferred from one cell to the next. Hand-over can briey interfere with communication and
may cause a delay, or at worst, disruption.
2.10 SIM Card Reader
EasyTunnel device is tted with two Mini SIM card readers designed for 1.8V and 3V Mini SIM cards. It is
the bar push type with tray and can be accessed through the front panel.
EasyTunnel presents the possibility of mounting two cards, one as a backup. In the front panel is identied
SIM card priority with the numbers 1 and 2.
