• 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
Use a LAN cable (Direct cable) and connect it to Ethenet1 of the BACnet Gateway
(Ethernet2 is reserved in case)
