1 INTRODUCTION
1.1 Wireless network
Wireless sensors are vital in monitoring construction sites, large structures and landslide areas. They are
extensively used in applications where geotechnical and other sensors are used for data collection and
transfer it to a central server for access by multiple users. Encardio-rite offers an innovative network
solution that allows real-time monitoring of geotechnical and structural sensors in challenging conditions
with reliable data transfer without any delay.
In Encardio-rite's comprehensive wireless monitoring system, the sensors are seamlessly integrated into
a long-range, low-power radio frequency (RF) network via suitable nodes, connecting them to a gateway.
This efficient setup allows the sensors to transmit recorded data to the gateway via the RF network with
utmost reliability. Subsequently, the gateway effortlessly uploads the collected data from the sensors to a
central or cloud server.
The system operates on ISM sub 1 GHz operating frequency bands adjustable to requirement of each
territory. The system can be adjusted to different frequency bands; for example: .
India 865 – 867 MHz
Europe 868 MHz
USA/Canada/Singapore/Australia 915 MHz
A detailed reference for frequency bands allowed in different Countries is available at:

1.2 Conventions used in this manual
WARNING! Warning messages calls attention to a procedure or practice that if not properly followed could
possibly cause personal injury.
CAUTION: Caution messages calls attention to a procedure or practice, that if not properly followed may
result in loss of data or damage to equipment.
NOTE: Note contains important information and is set off from the regular text to draw the users’
attention.
1.3 How to use this manual
This users’ manual is intended to provide you with sufficient information for making optimum use of
Gateways in your applications.
To make the manual more useful we invite valuable comments and suggestions regarding any additions
or enhancements. We also request to please let us know of any errors that are found while going through
the manual.
NOTE: Installation personnel must have a background of good installation practices and knowledge
of fundamentals of geotechnics. Novices may find it very difficult to carry on installation work.
The intricacies involved in installation are such that even if a single essential but apparently
minor requirement is ignored or overlooked, the most reliable of instruments will be rendered
useless.

2 GENERAL DESCRIPTION
2.1 Gateway
The Encardio-rite model EWG-01 wireless Gateway is used as a main networking hardware, which uploads
data gathered from all the geotechnical sensors connected to suitable nodes, to the remote server.
The gateway enabled with wireless network provides reliable data transfer over long distances, without
any delay. It is a rugged outdoor unit (IP66) specifically designed for long-term monitoring in harsh
environments. By enabling continuous data logging and real-time monitoring, it plays a crucial role in
providing early warnings for potential failures, allowing ample time for corrective actions or even safe
evacuation if required.
One of the notable advantages of the wireless system is its ability to eliminate the need for extensive cable
installations. This proves particularly beneficial in areas where sensors are spread over a wide
geographical range, making cable routing both challenging and risky. Additionally, stakeholders have
round-the-clock access to the collected data, ensuring constant availability and collaboration.
Furthermore, through the implementation of our cloud-hosted data management and configuration
software, the system can be tailored to automatically generate reports and trigger alerts via SMS or email
whenever readings surpass pre-defined alert thresholds. This intelligent automation streamlines operations
and enhances responsiveness.
Gateway features
Design, configuration and supervision of entire wireless sensor network.
Data collection from various sensors in the network.

4 PRE-INSTALLATION PREPARATIONS
4.1 Pre-installation checks
Before installation please check the gateway for any physical damage.
Open the gateway box to check if the internal wirings are intact.
4.2 Selecting location for Gateway
Selecting correct locations for Gateway and nodes is important, especially in case more than one nodes
are being installed at site and connected to single gateway.
The first step is to install the Gateway at a location that is in line of sight with all the installed nodes or in
line of sight with most of the nodes. The best location will have to be determined at the site itself. For best
results, the link between the gateway and the node should be strong, preferably better than -100 dBm.
Please note, the stronger the link better will be the results.
4.3 Setting up the Gateway & Nodes
It is recommended that the setting up and configuration of nodes and gateway is done before mounting the
nodes and gateway at respective installation location.
The gateway configuration needs to be done before nodes. Configuration of gateway is discussed in
Section 6 of this manual. For setting up and configuring the nodes and wireless tilt meters, please refer to
respective User’s Manual.

7 INSTALLATION PROCEDURE
Sites being different from each other must be properly surveyed to determine the best place for mounting
the gateway. Generally, the gateway should be in line of sight of all the nodes and if this is not possible in
line of sight with most of the nodes. In a hilly region, the best place to mount a gateway may be a portable
cabin from where all the nodes are visible.
A good place to mount the gateway maybe on a mast on the tallest building in the neighbourhood. To
achieve better coverage/transmission of data, it is recommended that the gateway (antenna) be mounted
at the site as high as practicably possible.
7.1 Wall mounting
Gateway box is provided with mounting holes. To install the Gateway on pole, fix the gateway mounting
plate provided with the supply to the gateway box. Fix the pole mounting bracket to the pole. Fix both the
antenna at the top of the pole using antenna mounting bracket as shown in the figure below.
Figure 7-1 Gateway mounting holes details
7.2 Mast mounting
Mounting the gateway on a tall mast is a good solution to achieve better height. Extra precaution must
however be taken for protection of the equipment.
Type of mast to be used for any application depends on the site conditions. Mast maybe a small pole
mounted to the roof of any structure or a tall pole in an open field structured on a strong foundation. If
required, the mast maybe supported with guy wires.
Once a stable mast is ready the gateway can be fixed on it using suitable clamps and the mounting plate.
A typical installation photograph is shown in figure -2 for reference. A protection box may be provided,
depending on site requirement.
NOTE: Mast, mounting accessories, protection cover and necessary civil work is in the scope of the
client.
Installation may have to be improvised or tailor made depending upon site conditions.

NOTE: Depending on the type of antenna used, cellular and RF antenna can be either installed over
the mounting bracket fixed on pole, or can be directly mounted on the respective connecters
provided at the bottom of gateway.

8 TROUBLESHOOTING
If the gateway is not connecting to the internet automatically, please follow these troubleshooting
steps:
Verify that all deployment steps have been executed accurately, giving particular focus to the cabling.
It is crucial to confirm that the gateway has been appropriately connected before powering it on.
Incorrect cabling can result in the gateway booting up without network connectivity or a SIM card.
Attempt to reboot the gateway using the ON/OFF switch. After the reboot, check if the gateway
successfully establishes an internet connection.
Verify that the 4G antenna is securely and properly connected. Ensure that the antenna connecting
cable is undamaged and correctly attached.
If the above steps do not resolve the issue, please refer to the user manual for further guidance or
contact ER for additional assistance.
Unable to connect Gateway over Bluetooth
Android phone’s Bluetooth may not be enabled.
Bluetooth modem may be out of Bluetooth range from android phone.
Bluetooth modem may not be paired with android phone.
Check Bluetooth modem baud rate settings. It must be configured for 115200 and hardware flow
control should be OFF.
Turn OFF the Node and then turn ON again.
Remove the power from node, wait for 30 seconds and then connect the power again. Now try to
connect.
Unable to communicate with Nodes
Check the antenna for loose connection.
Antenna to RF modem connecting cable may be damage.
Antenna itself may be damaged try with another antenna.
