2 Setting the Operating Environment
Given below is an explana tion of the PC s ettings and web browser settings that are requir ed for us ing a web
browser to monitor air conditioner units and perform operations.
2-1 Setting the PC IP Address
You need to set an IP addr ess on the PC that will enable you to connect to the G -50A using a web browser.
For instance, if the G-50A IP address is [192.168.1.1], the PC IP address will need to belong to the sam e
system (for example [192.168.1.101]).
If the G-50A is connected to an existing LAN, ask the LAN administrator to decide what PC IP address to use.
Note: When using a G-50A dedicated LAN, we recommend the G-50A main unit be given an IP address within the
range [192.168.1.1] — [192.168.1.40] and the PCs that will be connected to the G-50A be given an IP address
within the range [192.168.1.101] — [192.168.1.150]
(1) Click on [Control Panel] under [Start] to open the Control Panel.
(2) In the Control Panel window, double click [Network and Dial-up
