Hardware Installation
(1) Setting the indoor unit address
•By considering the entire installation configuration connecting to one BACnet Gateway, set the
unique address for each indoor unit. (We recommend to reflect it to the installation drawing.)
•Two hexadecimal digits 00~FF can be set to the address of the indoor unit.
•For the Multi V product, in order to identify the system component, we recommend to set the outdoor
unit number to the first digit of the address and the indoor unit number to the second digit.
•The ventilating product can be also installed and controlled by the BACnet Gateway.
(However, the address of the ventilation product cannot be set to overlap the address of the air
conditioner.)

(3) Connecting PI485 –BACnet Gateway
1. When connecting two or more PI485s to one BACnet Gateway, connect each BUS-A/BUS-B of
other PI485s to be connected to BUS-A/BUS-B of the PI485.
2. Connect the BUS-A of the PI485 to the TX of the BACnet Gateway and the BUS-B to the RX.
•Connect LG-NET 1~4 to any of the BACnet Gateway. (Connect the LG-NET to the RS485 port)
•64 outdoor units at maximum can be connected to each 485 port of the BACnet Gateway and the
number of indoor units to be connected to the BACnet Gateway is 256 at maximum.
Note: Disconnect the connector from the 485 port of the BACnet Gateway, connect the BUS-A to
the TX and the BUS-B to the RX by using the (-) driver, and then connect the connector to the
485 port of the BACnet Gateway. Because the 485 communication line has a polarity, connect
the line correctly.
