• 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 Bridge should not be removed. No configuration or maintenance action of the components (e.g. jumpers 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 Bridge.
• The Bridge must be mounted on a DIN rail in a cabinet or in an electrical box.
• When the Bridge 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 Bridge 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 Bridge is not compatible with a Power-Over-Ethernet (POE) network. Connecting the Bridge to a network segment carrying power may cause a failure. In this case, you must disconnect the Bridge from the POE network segment, turn it off and on again.
  • To avoid any risk of injury caused by a fall, the Bridge 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.

  • To Connect the Bridge to the BMS

To Connect the Bridge to the BMS

• Determine the type(s) of network(s) associated with the BMS (communication protocols between the BMS server and the technical equipment).
• Obtain, if possible, the schematic of the communication network(s) of the BMS.
• Identify where and how the BMS server connects to the building’s network.

IP Network Connections

• Make sure to have an Ethernet cable
•  Connect the cable to the Ethernet port of the Box ETH1 or ETH2.
• Connect the Box to the switch (IP network) on which the supervision PC/BMS server is connected.
• Check that the ETH1 or ETH2 LED lights up.

Configuration

• If there is no DHCP server on the network, attribute a static IP address, its mask and the gateway if necessary to the Box (Discuss with the building’s IT manager).
• If there is a DHCP server on the network, the address is automatically assigned.

Information to retrieve in preparation for the configuration:

• For each device that communicates in Modbus IP
  • 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 Bridge

• NB – These instructions assume that the LoRa sensors/devices have already been added to the Bridge.
• Setting up an Ethernet port on the Bridge
• There are 2 Ethernet ports on the Bridge, 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 Bridge ‘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 Bridge 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 ‘Bridge Configuration’ tab of the Sontay User Console, then click on the ‘Gateways’ tab.
