8INSTALLING THE INTERNET BRIDGEINSTALLING THE INTERNET BRIDGECheck 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 beconnected. (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 theperson 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 correspondingsocket 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.Mobile App Usage Environment<Recommended Specification>* According to the smart phones, some functions may not work or some screens may not be dis-played properly. * This app is optimized for the above recommended specifications, some actions can not in otherenvironments.* This App may not work in Tablet.Mobile App may be updated to improve usability / design or to reinforce the contents.
