¢ Configuration procedure
The following procedures presume that all VRF indoor/outdoor units are commissioned and opera-
tional, and that BACnet network toward the BMS workstation is operational.
1. Turn on the device.
Power supply working with any of the voltage range allowed is necessary. Once connected the
LED power will turn on.
2. Connect to BACnet interface.
Connect the communication cable coming from the network hub or switch to the Ethernet port
of the gateway. The cable to be used is a straight Ethernet STP CAT5 or higher cable.
In case there is no response from the BACnet devices to the frames sent by gateway, check
that they are optional and reachable from the network connection used by the gateway.
Check the gateway Ethernet interface sending pings to its IP address using a PC connected to
the same Ethernet IP network. If the problem persists communicating through the LAN of the
building, contact the network administrator.
BACnet gateway for VRF systems comes with DHCP functionality enabled by default.
3. Connect to VRF network.
Use the Lon connector in the left bottom corner of the gateway in order to connect the VRF net-
work to BACnet gateway.

4. Connect to PC (Configuration tool).
This action allows the user to have access to configuration and monitoring of the device. Two
methods to connect to the PC can be used:
• USB cable: To connect the device to the PC the USB cable supplied should be plugged to
USB console port. (This method is recommended.)
• Ethernet: Using ETH port of the gateway
NOTE: Install the configuration tool to the PC before connecting to the gateway.
5. Execute the configuration tool from the PC and perform necessary settings.
For details, refer to Instruction manual.
6. Perform scan from the configuration tool, and check that all VRF indoor/outdoor units are de-
tected and available.
7. Remove the USB cable from the gateway, and close the case.
In this stage, BACnet gateway should be accessible from the BMS workstation. Integration of
BACnet system is ready to be performed.
