1 Introduction
A special feature of Mitsubishi Electric Corporation’s “Central Controller G-50A” and "Central Controller
GB-50A" are that a PC con nected to a LAN can be us ed to m onitor the operat ion condition of air c ondit ioners
and perform air conditioner operations.
In this manual, the procedures to monitor the status of and to operate the central controller G-50A and GB-50A
on the Web browser are described.
Hereinafter, the central controller G-50A and GB-50A, unless otherwise specified, will be called "G-50A".
Note: License of "W eb Monitor" or "GB-50 A License Pack (available o nly in GB-50A) " is necessary to
operate or mointor the air conditioners. Register the license on the registration screen.

2 Setting the Operating Environment
Given below is an explana tion of the PC settings and web browser settings that are requir ed 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 addr ess on the PC that will enable you to connect to t he G-50A using a web browser.
For instance, if the G- 50A IP address is [192.168.1.1], the P C IP address will need to belong to the s ame
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 Netw ork and Dial-u p Connec tion s windo w 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) Prop erties] 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 admini stra tor to provide the IP addresses and subnet
mask.
(5) Click the [OK] button to close th is dialog, and then clos e 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.
2-2-1 Not connecting to the Internet
If the PC you use for monitoring air conditioners and performing operations is not going to be connected to the

3 Performing Operations
Given below is an ex planation of ho w to connect to the G -50A and how to m onitor 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 operati on 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)

operation, click [OK] and the operation settings for only the
adjusted items will be sent to all the air conditioner units contained
in the selected block. To return to the previous screen without
performing any operations, click [Cancel].
Note: When resetting the filter sign as part of a one-block batch operation, the
accumulated ON time used to trigger the filter sign will be reset in all
units belonging to the selected block, irrespective of whether or not the
filter sign was triggered. Use the reset filter sign operation in a batch
operation in a case such as when all the unit filters in the same batch
are cleaned at once.
Note: When allowing remote controller operation under K control, all prohibit
remote controller operation items must be set enable.
3-3-3 Performing air conditioner operations that target all groups
(1) Click [Batch Operation] from the operation condition monitoring
screen that displays all groups in a list. If the system contains both
air conditioner gr oups and LOSSNA Y groups, a select ion screen
appears asking you to select whether to set air conditioners or

and the screen to set the batch operation will appear.
If the system has only air conditioner groups or only LOSSNAY
groups, this selection screen will not appear.
(2) After you have made the settings on the screen for batch
operation, click [OK] and the operation settings for only the
adjusted items will be sent to all the air conditioner units.
To return to the previous screen without performing any
operations, click [Cancel].
Note: When resetting the filter sign as part of an all-groups batch operation,
the accumulated ON time used to trigger the filter sign will be reset in all
units, irrespective of whether or not the filter sign was triggered. Use the
reset filter sign operation in a batch operation in a case such as when all
the unit filters are cleaned at once.
