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.
