2.6Web interface features
Web-based administration
The gateway services and the transmitters network can be quickly configured through a web-
based service.
Role-based access control
Access to the web-based service is restricted only to registered users. The security policy is
based on the authentication mechanism through the username and password with a function
permission scheme that sets the level of access to certain resources and the authorization to
perform certain operations.
Modbus slave-server
Support for Modbus RTU protocol (through RS-485 port) and TCP (Ethernet port). The gateway
exposes a Modbus slave (RS485) or Modbus server (TCP / IP) providing all the information of
the transmitters connected in a map of holding registers.

DUOS IoT GATEWAY Product Manual

Integration with cloud service providers
The DUOS IoT Gateway is incorporated in the Internet of Things, connecting to an application
running in the cloud through an IoT platform. Native integration with Tekon IoT Platform. It
can be integrated into other external platforms through the REST API interface.
Event-driven, scalable, distributed architecture
Inter-communication between the internal services of the gateway is achieved through a
distributed architecture and controlled by events. Messages delivered to multiple recipients
at once are carried accross the TCP protocol, which allows applications outside the gateway's
network to have access.
3. Updates
Firmware and web interface updates for the Duos IoT Gateway are reserved exclusively for
Tekon Electronics. In case of a severe error, contact technical support to assess the problem
with your device.
4. Initial configuration
4.1. System requirements
The right use of DUOS IoT Gateway is relying on a set of requirements that must be
guaranteed.
4.2. Wireless network
The dedicated wireless network created by the DUOS IoT Gateway allows access to the device
directly for consultation and configuration, namely the IP address that was assigned by the
network to which it is connected via the Ethernet port.
When connecting to the dedicated wireless network, you can access to the gateway interface
by accessing IP address 192.168.128.1. If you are using mobile devices, make sure you have
your mobile data turned off.
More information on how to perform these steps can be found in the DUOS Installation
Guide, in topic 5, available for consultation on the Tekon Electronics website.
