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 central 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.

Note : Indoor unit address setting completed site

-The site that already completed the indoor unit address does not require address setting again.

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 system composition and division can be easily identified during the address setting.

Outdoor unit (group) number Indoor unit number

The following is an example of assigning addresses to the indoor unit.

Connecting PI485 cable (for MultiV SuperIII model or lower)

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.

10V GND BUS_A BUS_B

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.

12 INSTALLING THE INTERNET BRIDGE

Connecting PI485 cable (for MultiV Super IV)

1Connect the central controller communication line (RS485 cable) to the central control connector (CEN_A, CEN_B) of the external board.
