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) 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.

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].

(3) Check the radio button next to [Never dial a connection] in the middle

of the window, and click [OK] to close the window.

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].

(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 System Maintenance Engineer

(1) Enter the web page address in the address field of the Web browser as follows:

http ://[IP address of the EB-50]/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/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.

1. Click [Tools] in the menu bar, then click [Internet options].

2. On the [General] tab, click [Delete] in the middle of the window.

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.

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]/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/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.
