2. Setting the Operating Environment
This chapter explains how to make PC settings and Web browser settings to monitor and operate the air
conditioning units.
2-1. Setting the IP Address of the PC
Follow the instructions below to set the PC’s IP address for the Web browser to recognize the AE-200 unit.
The PC’s IP address must have the same network address as the AE-200/AE-50’s IP address.
(i.e., AE-200’s IP address: [192.168.1.1], PC’s IP address: [192.168.1.101])
When connecting an AE-200/AE-50 to an existing LAN, consult the system administrator to decide the IP
addresses.
Note: When using an AE-200/AE-50-dedicated LAN, it is recommended that the AE-200 unit be assigned an IP address
between the range [192.168.1.1] and [192.168.1.40], the AE-50 unit be assigned an IP address between the range
[192.168.1.211] and [192.168.1.249], and that the PC connected to the AE-200/AE-50 be assigned an IP address
between the range [192.168.1.101] and [192.168.1.150].
(1) Click [Control Panel] in the Start menu.
(2) Click [Network and Sharing Center]>[Local Area Setting].
In the [Local Area Connection Status] window, click [Properties].
(3) Click [Internet Protocol Version 4 (TCP/IPv4)] to select it, and click
[Properties].

4
WT07139X01
(4) In the [Internet Protocol Version 4 (TCP/IPv4) Properties] window,
check the radio button next to [Use the following IP address].
Enter the PC’s IP address (e.g., [192.168.1.101]) in the [IP address]
field, and enter the subnet mask [255.255.255.0] (unless otherwise
specified) in the [Subnet mask] field.
In the [Default gateway] field, enter the gateway address as necessary.
Note: Consult the system administrator to decide the IP, subnet mask, and
gateway addresses.
(5) Keep clicking [OK] or [Close] to close all windows.

Note: The license “Personal Web” is required to register up to 50 general users and to specify the accessible unit groups for
each general user. Refer to section 8-2 “User Registration” for details.
Note: It is recommended to change the default user name and password so that the users other than the building managers
and general users will not be able to change the settings.
Note: When one or more AE-50 controllers are connected, log in to the AE-50 Web browser to monitor or operate the units that
are under the control of AE-50 controllers. The Web browser cannot be switched between the AE-200 and the AE-50.

WT07139X01
Encrypting the communication data and logging in to the Web browser
(HTTPS connection)
AE-200/AE-50 can encrypt communication data using HTTPS (SSL).
When connecting the AE-200/AE-50 to the LAN that is accessible to the general public, it is recommended that
the following settings be made so that the units are monitored and controlled on the encrypted web page.
Note: Depending on the operating system or the Java version, HTTPS encrypted communication may not be enabled properly.
If this happens, use an HTTP connection as explained in the previous page.
(1) Prefix the web address with [https], enter the rest of the address, and
press the [Enter] key.
https://[IP Address of each AE-200/AE-50]/administrator.html
Note: If the IP address of the AE-200/AE-50 is [192.168.1.1], the web page
address is [https://192.168.1.1/administrator.html].
The encrypted data communication will begin, and the Login screen
will appear.
If a security certificate error page appears instead of the Login screen,
go to step (2) below.
(2) If the security certificate is invalid, a security certificate error page (as
shown at right) will appear.
Click [Continue to this website (not recommended)].
(3) If the connection is successfully made, the Login screen will appear.
Note: Although the address bar will turn red and a message “Certificate error”
will appear, you can still access the Web browser.
