(4) Connecting Internet – BACnet Gateway
• In the case connecting a BACnet Gateway to the internet which is already installed in the site, there
should be a HUB which is already installed.
In the case, being able to inter-work with the BMS system using the internet and connecting a
BACnet Gateway to the internet which is already installed in the site : Use the HUB
Note: Through the test operation of BACnet Gateway, it can be judged whether the installation is
properly done or not (instead of using the HUB, connecting the BACnet Gateway with a cross
cable)
• Be aware the type of the cable youʼre using (the Direct cable or the Cross cable)
• Prior to the Connecting, Check whether the cable works properly or not through the LAN tester.
• After applying the power to the DC adapter provided, Turn on the power switch.
■ In the case using HUB

(Ethernet2 is reserved in case)
