2 Setting the Operating Environment

PC settings and web browser settings required for using a web bro wser to monitor air conditioner units and perform operations are explained in the following pages.

2-1 Setting the PC IP Address

Set an IP address on the PC that enables GB-24A to connect via a web browser. For instance, if the GB-24A IP address is [192.168.1.1], the PC IP address will need to belong to the same system [192.168.1.101]. If the GB-24A is connected to an existing LAN, ask the LAN administrator to decide what PC IP address to use.

Note: When using a GB-24A dedicated LAN, it is recommended that the GB-24A main unit be given an IP address

within the range [192.168.1.1] — [192.168.1.40] and the PCs connected to the GB-24A 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

Connections] and the Network and Dial-up Connections window will open. Double click on [Local Area Setting] and the [Local Area Connection Status] dialog will open. Click [Properties].

(3) In the [Local Area Connection Properties] dialog, click [Internet

Protocol] to select it and click the [Properties] button.

(4) In the [Internet Protocol (TCP/IP) Properties] dialog, click [Use the

following IP address] and enter the IP address (for example, “192.168.1.101”) that you want to set in the IP address field. You normally set [255.255.255.0] as the subnet mask.

Note: Ask your LAN administrator to provide the IP addresses and subnet mask.

(5) Click the [OK] button to close this dialog, and then close the other open

dialogs to complete the network setting.

2-2 Setting the Web Browser

Necessary web browser settings must be performed to enable the web browser to connect to the GB-24A.

Note: The settings and screen images used as examples in this manual are based on Internet Explorer 6.0.

Exceptions field of the Proxy Setting dialog and click the [OK] button to close the dialog and then close the other open dialogs to complete the setting.

Note: If connecting to more than one GB-24A, you can specify multiple IP addresses

like [192.168.1.1; 192.168.1.2], however, it is also possible to use the asterisk (*) and specify [192.168.1*].

3 Performing Operations

Text below explains how to connect to the GB-24A and how to perform various settings.

Note: If the GB-24A is restarted due to a power interruption etc., wait until the screen on the GB-24A main unit displays the normal

operation screen (it takes several minutes before the normal operation screen is displayed) before using a web browser to access the GB-24A. If access is attempted while the GB-24A is still starting up, the most recent data might not be displayed or communication errors could occur.

Note: Default IP address of GB-24A is "192.168.1.1". (Factory setting)

3-1 Entering the User Name and the Password, and Connecting to

the GB-24A

(1) Enter the web page address in the address field of the web

browser as follows:

http:// [IP address of the GB-24A]/g-50/ administrator.html

Press the [Enter] key on the keyboard. A screen appears for login.

Note: For example, type “http://192.168.1.1/g-50/administrator.html” if the

GB-24A IP address is [192.168.1.1].

(2) To make connection easier for the next time, click the web

browser menu item [Favorites], click [Add to Favorites], then add the address to the Favorites folder. Once this address is added to the Favorites folder, it is not necessary to input the address of (1). Simply select it from the Favorites folder and the GB-24A page will appear.
