INSTALLING THE INTERNET BRIDGE
Check list before installing the internet bridge
• When you configure the internet bridge network, you can connect up to 16 outdoor units.
Internet bridge composes the network with RS-485, and up to 16 outdoor unit PI485s can be
connected. (But, you can connect up to 31 SINGLE / Ventilation PI485s.)
• Internet bridge can connect up to 16 indoor units or Ventilator.
• During the configuration of the internet bridge RS-485, check the polarity.
RS-485 is divided to BUS-A and BUS-B.
If the corresponding Port is switched, there will be no communication, so be careful.
(RS-485 communication line can be used up to 1Km.)
• Internet bridge can be connected to internet.
You need to request the internet bridge’s IP address, Gateway address, and Netmask to the
person in charge of the network in the corresponding site.
• Check if other installed central controllers are set as Slave mode.
Internet bridge only works as Master mode, and it cannot interface with in master mode cen-
tral controller.
• Power socket shall be near the internet bridge power connection part, and the corresponding
socket shall be easily accessed.
• SSID and password of wireless router supports only ASCII code.
• Internet bridge supports only wireless router that uses the signal of 2.4GHz band.

• When it is installed as wired cables
Connect wired LAN cable of 10m or less to the internet bridge.
Protect the exposed wired LAN cable with cable pipe.
• Power connection
Internet bridge shall be installed within 2m from the power socket.
Arrange and connect the power cable.
• RS485 cable
It shall be installed at a place where it is connected to RS485 connecting to the outdoor unit.
• Indoor installation
Internet bridge shall be installed indoor, not outdoor.
Do not install at a place exposed to rain or with a lot of moisture.
Do not store or use flammable gas or inflammables near the product.
10 INSTALLING THE INTERNET BRIDGE
Note : Indoor unit address setting completed site
- The site that already completed the indoor unit address does not require address setting
again.
Note : How to set the indoor unit’s central control address
- According to the indoor unit product or the type of the remote controller, the methods of
setting the central control address may be different, so refer to the indoor unit product or
wired remote controller manual for the address setting.
Note : Assignment of outdoor unit and indoor unit number
- If the outdoor unit product is Multi V, it is recommended to set the first digit of the address
with outdoor unit number, and set the second digit with indoor unit number, so that the sys-
tem composition and division can be easily identified during the address setting.
Indoor unit address setting
The addresses of the indoor units connected to one internet bridge shall be assigned without
overlapping. You can set the indoor unit address as hexadecimal 00 ~ FF.
The following is an example of assigning addresses to the indoor unit.

When you install PI485, you need to set DIP switch.
(For DIP switch setting, refer to each PI485 manual.)
After installing PI485, connect RS-485 cable.
To connect PI485 and the internet bridge, two RS-485 cables shall be connected to PI485’s
BUS_A and BUS_B.
Refer to the following figure to connect RS-485 cable.
If several PI485’s are connected to the internet bridge, connect the cable’s BUS_A part to BUS_A
connector of each PI485, and connect cable’s BUS_B part to BUS_B connector of each PI485.
