4 Getting Started with the Configuration
Manager
The VisionNet 202ER includes preinstalled program called the
Configuration Manager, which provides an interface to the software
installed on the device. It enables you to configure the device
settings to meet the needs of your network. You access it through
your web browser from any PC connected to the VisionNet 202ER
via the LAN port.
This chapter describes how to use the Configuration Manager.
Note
The VisionNet 202ER may already be configured to provide Internet
connectivity for your network. If it works properly with the
preconfigured settings, then you may not need to use the
Configuration Manager. Contact your ISP to determine which
settings you may need to change, if any.
Accessing the Configuration Manager
The Configuration Manager program is preinstalled into memory on
the VisionNet 202ER. To access the program, you need the
following:
A PC or laptop connected to the LAN port on the device as
described in the Quick Start chapter.
An web browser installed on the PC. The program is
designed to work best with Microsoft Internet Explorer®
version 5.0, Netscape Navigator® version 6.2, or later
versions.
You can access the program from any computer connected to the
VisionNet 202ER.
1. From a LAN computer, open your web browser, type the
following URL in the web address (or location) box, and
press <Enter>:
http://10.0.0.2
These are the predefined IP addresses for the LAN ports on the
VisionNet 202ER.
A login screen displays, as shown in Figure 7.

2. Enter your user name and password, and then click
.
3. The first time you launch the program, use these defaults:
Default User Name: admin
Default Password : visionnet
Note
You can change the password at any time (see Changing Your
Login Password on page 35). The user name cannot be changed.
The System View page displays each time you launch the
program (shown in Figure 8 on page 31).
