- Connect the cable to the Ethernet port of the Hub ETH1 or ETH2.
- Connect the Hub 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 not a DHCP server on the network, attribute a static IP address, its mask and the gateway if necessary to the Hub (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, recuperate 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.
In the case of the LON IP-852 network
Connection:
- Make sure to have an Ethernet cable.
- Connect the cable to the Ethernet ports of the Hub ETH1 or ETH2.
- Connect the other end of the cable to the IP-852 server on the LON network.
- Verify that the ETH1 or ETH2 LED lights up
- Register the IP address of the Hub on the IP-852 server of the LON network; the IP-852 server’s password is probably required.

- If the signal quality is insufficient: move the original antenna out of the cabinet; use an RF extension cord with an SMA connector up to 2 meters + 1 adhesive support to hold the antenna.
- If the signal quality is still insufficient: use a High-gain antenna with a maximum of 10 meters of cable; this antenna can for example be used outside or in other floors to obtain the best signal quality.
For each sensor:
- Add the sensor to the Desktop Application by naming it so it can be identified.
- Send the configuration to the Hub.
- Activate the sensor; to do this, use the manufacturer’s technical documentation.
- Check on the Desktop Application that the sensor is detected.
GSM Antenna
We recommend connecting the GSM antenna to allow remote support to the Hub when needed.
In that case:
- Connect the standard GSM antenna supplied with the Hub.
- Wait for the GSM LED to flash.
- If the quality of the GSM signal is good: keep the original antenna installed on the Box.
- If the signal quality is insufficient: move the original antenna out of the cabinet; use an RF extension cord with an SMA connector, up to 2 meters, + 1 adhesive support to hold the antenna.
- If the signal quality is still insufficient: use a high-gain antenna with a maximum of 10 meters of cable; this antenna can, for example, be moved to the outside or to the other floors to obtain a better signal quality.
- Please note that, beyond 15 meters of cable, the GSM signal is significantly weakened.
