Safety Rules
• Incorrect wiring of this product may damage it and cause other hazards.
• The product must be installed by a qualified professional.
• Make sure the product has been wired correctly before turning on the power.
• Before wiring, removing, or mounting the product, be sure to turn off the power. Failure to do so may result in electric shock.
• Do not touch electrically connected parts, such as power terminals. Doing so may result in electric shock.
• Do not disassemble the product. Doing so may result in electric shock or malfunction.
• Use the product within the operating ranges recommended in the specifications (temperature, humidity, voltage, shock, mounting
direction, atmosphere, etc.) Failure to do so may result in fire or malfunction.
• Tighten the electrical wires on the connector. Insufficient tightening of the wires on the terminal may cause a fire.
• Disconnect the power supply before installation or maintenance to avoid electric shock or property damage.
• Use only copper conductors. Make all connections in accordance with local, state, and national electrical codes.
• To reduce the risk of fire or electric shock, install the equipment in a controlled environment relatively free of contaminants.
• This equipment is intended for use as a monitoring and control device only. To avoid loss of data or damage to the equipment, do
not use it for any other purpose.
• The cover or front panel of the Hub should not be removed. No configuration or maintenance action of the components (e.g. jump-
ers or battery) by the user requires the removal of the cover; all elements are accessible as connectors on the top, bottom, and side
of the Hub.
• The Hub must be mounted on a DIN rail in a cabinet or in an electrical box.
• When the Hub is mounted inside an enclosure, make sure the enclosure is designed to maintain the required operating temperature
range (allowing for 24 watts of dissipation by the controller). This is especially important if the Box is mounted inside an enclosure
with other heat-producing equipment.
• This product is intended for indoor use only.
• Do not install the Hub in an area:
- Where there is excessive moisture, corrosive fumes, or explosive vapours
- Where vibration or shock is likely to occur,
- Subject to electrical noise, e.g. near large electrical contractors, electrical machinery, welding equipment, etc.
• This equipment is not suitable for use in areas where children may be present.
• The Hub is not compatible with a Power-Over-Ethernet (POE) network. Connecting the Hub to a network segment carrying power
may cause a failure. In this case, you must disconnect the Hub from the POE network segment, turn it off and on again.
• To avoid any risk of injury caused by a fall, the Hub should not be installed more than 2 meters from the ground.
EN 60730-1 Power supply considerations
• Electrical safety in building automation and control systems relies primarily on the use of extra-low voltage, strictly separated from
the mains voltage.
This low voltage is either SELV or PELV, according to EN 60730-1.
• Protection against electric shocks is ensured by the following measures:
- Voltage limitation (low voltage supply 24Vdc DC ±10%, SELV or PELV),
- Protective separation of the SELV system from all circuits other than SELV and PELV,
- Simple separation of the SELV system from other SELV systems, PELV systems and the ground.
• Field devices such as sensors, status contractors, or actuators connected to the low voltage inputs and outputs of the I/O modules
must comply with SELV or PELV requirements. Interfaces to field devices and other systems must also comply with SELV or PELV
requirements.
• When power for SELV or PELV circuits is obtained from higher voltage power systems, it shall be provided by a safety transformer
or converter designed for continuous operation to power the SELV or PELV circuits.

• Make sure you have 2 Ethernet cables.
• Connect the cables to the Ethernet port of the Hub ETH1 and ETH2.
• Connect the cables to the 2 devices.
• Check that the LED ETH1 and ETH2 lights up.
To connect 3 or more devices
- Have an Ethernet cable for the Hub.
- Have as many Ethernet cables as equipment to connect.
- Have an Ethernet switch.
- Connect the switch to the power supply.
• Connect an Ethernet cable to the Ethernet port of the Hub ETH1 or EHT2.
• Connect the other end of this cable to the Ethernet switch.

• Check that the ETH1 or ETH2 LED lights up
• Connect all equipment to the switch via the Ethernet cables.
To configure each one of the equipment:
• Using the technical documentation of the equipment, find its IP address and TCP port (and if necessary, for some devices, the address
of the slave "Slave ID").
• If the equipment does not have an IP address, assign one to it, 192.168.1.1 for the first device, then 192.168.1.2 for the second device,
192.168.1.3 for the third device, and so on.
• Write down the IP address and TCP port (and if necessary, for certain devices, the address of the Slave ID), the brand and model of
the equipment, and any information that allows it to be identified. This information will be necessary for the installation configuration
and to retrieve data.
- From the BMS software, perform an extract of the available properties: list the data types provided by the different devices to
which the BMS has access.
- If it is impossible to retrieve this information, get the IP address and TCP port (and if needed, for some devices, the slave
address (Slave ID), the brand, and model of the equipment, and extra identifying information. This information is necessary for
the installation configuration and to retrieve data.
• In the case of a BACnet IP network
- Write down the BACnet port of the network. This information will be necessary for the installation configuration and to retrieve
data.

Setting up a BACnet IP Network on the Hub
NB - These instructions assume that the LoRa sensors/devices have already been added to the hub.
Setting up an Ethernet port on the hub
There are 2 Ethernet ports on the hub, ETH1 and ETH2. It doesn’t matter which you use, but if one is already used it’s probably best to have
the other configured for a different domain, for example:
• If ETH1 is configured for 192.168.1.xxx, then enter 192.168.0.xxx or 10.0.20.xxx for ETH2 for example.
Click on the Hub ‘Configuration’ tab on the Sontay User Console, then click on the ‘Connectors’ tab. A list of available connections should be
visible, including ETH1 and ETH2 at the top of the list.
Click on the edit icon to the right of the Ethernet port you want to use. Here, you can set up the Ethernet port configuration.
By clicking on the ‘Method’ drop-down box, the initial options are either;
• Manual – the allows you to define the IP address and subnet mask, or
• DHCP (Dynamic Host Configuration Protocol), which will allow the hub to be automatically assigned an IP address from the DHCP
server on your network (if installed and enabled).
NB – If you choose DHCP, you may not immediately be able to tell what IP address has been assigned.
If DHCP is selected, all that needs to be done to finish the connector configuration is to click the ‘Save’ button at the bottom right of the screen.
If you elect to use manual settings, you will need to fill in the ‘IP Address’, ‘Netmask’ and ‘Gateway’ fields (see next page).

• Make sure you don’t use an IP address that’s already taken on the same domain and network – if you do, you’ll lose comms to both
devices.
• Leave ‘Netmask’ at the default setting of 24 (unless you have reason to change it)
• Adding a Gateway IP address is optional, but if you know the IP address of your network gate, it’s always useful to use it.
• When you’ve filled in the settings, don’t forget to click the ‘Save’ button at the bottom right of the screen.
Setting up a BACnet IP Gateway
Click on the ‘Hub Configuration’ tab of the Sontay User Console, then click on the ‘Gateways’ tab.
Click on the ‘Create new gateway’ button.
Fill in all the required fields.
• Give the Gateway a name (for example, Test BACnet IP).
• The description, though optional, should be filled in, as a reminder for later.
• From the drop-down list of Protocols, select BACnet IP Gateway.

• Give the Gateway a name (for example, Test BACnet IP).
• The description, though optional, should be filled in, as a reminder for later.
• From the drop-down list of Protocols, select BACnet IP Gateway.
• Now, you’ll see extra fields to complete.
- From the ‘Physical Connector’ drop-down, select the Ethernet port you set up during “ Setting up an Ethernet port on the
hub” (ETH1 or ETH2)
- Leave the ‘UDP Port’ settings as they are.
- If required, you can change the ‘Device Instance’ and ‘Network number’. For example set the ‘Network number’ to 1 and ‘
Device Instance’ to 662001
- Here you can also give the hub a name and location.
NB - Click ‘Save’ at the bottom of the screen when complete.
