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 EB-50 unit.
The PC's IP address must have the same network address as the EB-50's IP address.
(i.e., EB-50's IP address: [192.168.1.1], PC's IP address: [192.168.1.101])
When connecting an EB-50 to an existing LAN, consult the system administrator to decide the IP address of the
PC.
Note: When using an EB-50-dedicated LAN, it is recommended that the main EB-50 unit be assigned an IP address
between the range [192.168.1.1] and [192.168.1.40] and that the PC connected to the EB-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
(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. (Refer to section 4-2-5 for details.)
Note: Consult the system administrator to decide the IP, subnet
mask, and gateway addresses.
(5) Keep clicking [OK] or [Close] to close all windows.

2-2. Setting the Web Browser
Web browser setting varies with the Internet connection type. See the sections below for how to make Web
browser settings for different types of Internet connection.
To prevent unauthorized access, always use a security device such as a VPN router when
connecting the EB-50 to the Internet.
2-2-1. No Internet connection
To monitor and operate the air conditioning units from a PC with no Internet connection, follow the instructions
below to set the environment for the Web browser.
(1) Click [Tools] in the menu bar, then click [Internet options].
(2) In the [Internet Options] window, click the [Connections] tab.
(3) Check the radio button next to [Never dial a connection] in the middle
of the window, and click [OK] to close the window.

6
2-2-2. Dial-up Internet connection
To monitor and operate the air conditioning units from a PC that connects to the Internet through a dial-up
connection, follow the instructions below to set the environment for the Web browser.
(1) Click [Tools] in the menu bar, then click [Internet options].
(2) In the [Internet Options] window, click the [Connections] tab.
(3) Check the radio button next to [Dial whenever a network connection
is not present] in the middle of the window, and click [OK] to close the
window.
By making these settings, a message will appear asking whether
or not to use a dial-up connection when an Internet connection is
necessary. Follow the message to connect to the Internet.
2-2-3. Connecting to the Internet via proxy server using an existing LAN
To monitor and operate the air conditioning units from a PC that connects to the Internet through a proxy server
by connecting to an existing LAN, such as a LAN within your company, follow the instructions below to set the
environment for the Web browser.
(1) Click [Tools] in the menu bar, then click [Internet options].

7
(2) In the [Internet Options] window, click the [Connections] tab.
(3) Check the radio button next to [Never dial a connection] in the middle
of the window.
(4) Click [LAN settings] under [Local Area Network (LAN) settings].
(5) In the [Local Area Network (LAN) Settings] window, check [Bypass
proxy server for local addresses], and click [Advanced].
(6) In the [Proxy Settings] window, enter the EB-50’s IP address (e.g.,
192.168.1.1) in the [Exceptions] field. Then, keep clicking [OK] or
[Close] to close all windows.
If connecting multiple EB-50 units, enter the addresses of all EB-50
units (e.g., [192.168.1.1; 192.168.1.2]). It is also possible to use an
asterisk as a wildcard (e.g., [192.168.1.*]).

3. Logging in to the Web Browser for Initial Settings
(1) Enter the web page address in the address field of the Web browser as follows:
http:// [IP address of the EB-50]/init/administrator.html
Press the [Enter] key. A login screen will appear.
Note: If the IP address of the EB-50 is [192.168.1.1], the web page
address is [http://192.168.1.1/init/administrator.html].
Note: Default IP address of EB-50 is [192.168.1.1].
Note: If the login screen does not appear then take the steps below
to delete the temporary files.
<Internet Explorer>
1. Click [Tools] in the menu bar, then click [Internet options].
2. On the [General] tab, click [Delete] in the middle of the
window.
3. In the [Delete Browsing History] window, click [Delete].
<Java>

2. Click the [Java] icon to launch the Java Control Panel.
3. On the [General] tab, click [Settings] in the [Temporary
Internet Files] section.
4. Click [Delete Files].
5. In the [Delete Files and Applications] window, click [OK].
Note: The web page will be displayed in the same language as the operating system on the PC.
The web page can be displayed in other languages by entering the web page address as follows:
Chinese http://[IP address of the EB-50]/init/zh/administrator.html
English http://[IP address of the EB-50]/init/en/administrator.html
French http://[IP address of the EB-50]/init/fr/administrator.html
German http://[IP address of the EB-50]/init/de/administrator.html

Encrypting the communication data and logging in to the Web browser
(HTTPS connection)
EB-50 can encrypt communication data using HTTPS (SSL).
When connecting the EB-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 the EB-50]/init/administrator.html
Note: If the IP address of the EB-50 is [192.168.1.1], the web page address is
[https://192.168.1.1/init/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.
