1 Introduction

A special feature of Mitsubishi Electric Corporation’s “Central Controller G-50A” and "Central Controller

GB-50A" are that a PC connected to a LAN can be used to monitor the operation condition of air conditioners

and perform air conditioner operations.

2 Setting the Operating Environment

Given below is an explanation of the PC settings and web browser settings that are required for using a web

browser to monitor air conditioner units and perform operations.

2-1 Setting the PC IP Address

You need to set an IP address 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 same

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

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

Perform the necessary web browser settings to enable the web browser to connect to the G-50A.

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

2-2-3 Connecting to the Internet using a proxy server (Using an existing LAN)

If the PC you use for monitoring air conditioners and performing operations is going to access the Internet via

proxy server by connecting to an existing LAN such as a LAN within your company, use the procedure given

below to set the web browser environment settings.

By performing these settings, your PC will connect to a proxy server only when connecting to the Internet.

(1) Click the web browser menu item [Tools] and then click [Internet

Options…] to select that option.

(2) In the [Internet Options] tabbed dialog, click the [Connections] tab to

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 G-50A, 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

Given below is an explanation of how to connect to the G-50A and how to monitor and adjust the operation

condition of air conditioners. Follow the directions given here when performing operations.

Note: If the G-50A is restarted due to circumstances like a power interruption, wait until the screen on the G-50A 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 G-50A. If access is attempted while the G-50A is still starting up, the most recent data

might not be displayed or communication errors could occur.

Note: Default IP address of G-50A (GB-50A) is "192.168.1.1". (Factory setting)

address is [192.168.1.1].

(2) To make it easier to connect the next time, click the web browser

menu item [Favorites] and click [Add to Favorites] to select that
