Product and Architectural Design information SRT MN-01
Functional description
The Scandinavian Reach Technologies AS SRT MN-01 Mesh Node is a wireless network device
intended to transport data in a Mesh network structure within steel confined areas. Several nodes
are connected via built-in radio transmitters. The data is collected from SRT PT-01 or other adequate
sensors via Bluetooth protocol. The end node is connected to a Gateway computer, collecting data
sent through the network.
The MN-01 Mesh node includes a pressable button in order to reset the node if necessary.
Furthermore, a LED diode is visible through the SRT MN-01 surface when the network is activated.
Installation manual:
The following steps cover necessary information to install and start MN-01
1. Plug one MN-01 via USB connection to the Gateway computer
2. Plug remaining MN-01 including power adapter into to power sockets in all relevant areas.
Areas to be defined in order confirmation.
3. Install MN-01 on appropriate surface with SRT supplied double sided tape.
4. MN-01 will start up and autonomously form the wireless mesh network.
a. This requires the backend to be configured with appropriate “white-lists” of allowed
devices on beforehand. Typically this is done by Scandinavian Reach Technologies AS
User manual:
Manual handling of MN-01 is not required in operation mode. Depending on application, any
deviation from normal functionality will be provided in relevant Graphical User Interface.
In case a reset is required, press the MN-01 front surface and hold for 3 seconds.
Software/Firmware specification
The mesh node is from factory equipped with firmware which serves two main purposes:
Participate in a mesh-network
The SRT MN-01 will when started try to join a mesh network using credentials already supplied on
internal flash. Joining a network can either happen by direct communicating with a “root” (the single
device connected to a computer), or by communicating with the root via other mesh nodes. A
combination of credentials and whitelisting ensures only known devices will be able to join the
network. After having joined a mesh network a mesh node will communicate with nearby mesh
nodes in order to act as a forwarder of received data and to balance the network according to signal
conditions where the node is placed.
