2 Setting the Operating Environment
PC settings and web browser settings required for using a web browser 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 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
(3) Enter the user name and the password in the login screen, and click the [Login] button. A screen will
appear in which various setting are made. Procedures for making proper settings on each screen will be
explained in the following pages.
The table below shows the default user names and passwords for maintenance users and managers, as
well as available functions.
Note: The user name and the manager’s password are the same as those of the manager of the Web for monitoring/operation.
Note: Maintenance users can make available to the administrator only the information necessary for normal operation (group
name setting etc.)
Note: It is recommended to change the user name and password, so users other than the manager are not permitted to change
the settings.
(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].
