To Connect to the unit over Ethernet
Make sure you have your ethernet cable plugged into the back of the exciter
unit. Navigate on the front of the exciter screen to the IP window and capture
the IP and Netmask address. On your computer, you will need to go under your
network settings and change your IP address to something on the same network.
In the example of the IP screen shown above, the IP address is 010.000.012.098 and the Netmask is 255.255.255.0 so you will need to go into your computer network settings and change your address to 010.000.012.010 or something. The last digit must be different than what is in the Exciter. Set the Netmask to 255.255.255.0.
Open your browser and enter the exciter IP address and you should come to the exciter login screen. Enter the username and password.
- Default Username: admin
- Default Password: system
You should now be connected to the exciter and see the main page.
To Change the IP address of the exciter
Connect to the exciter as shown above. From the main screen, left click on the
SYSTEM tab in the bottom corner to open it. This will open the system menu.
Under the Admin section, you can select LAN and there you can change your
exciter IP address. Once changed, you will be disconnected and must relog in.
You will also need to change your computer network setting to be back on the
same network you put the exciter on.
