Configuring Limit 8 M4 Encoder to Catapult Spec – Catapult Thunder Support

Adjusting the Limit 8 M4 to desired network properties

The Limit 8 M4 comes standard with a static IP of 10.1.1.131. To adjust the IP address, connect your PC directly to the Limit 8 M4 via Ethernet connection and adjust the IP address of your PC network adapter to 10.1.1.100 with a subnet mask of 255.255.255.0.

Once adjusted, you should now be able to access the web user interface of the Limit 8 M4 device by typing the IP address, 10.1.1.131, in a web browser.

Once you access the login page, use the default credentials of admin for the username and admin for the password

Once logged in, navigate to the System option on the left hand side of the UI. From here you can Toggle DHCP if desired or change the Static IP of the Limit 8 M4 to match your network scheme.

At this point you will lose connection to the Limit 8 M4 and will need to set your PC network adapter to an IP which matches the Limit 8 M4’s new network scheme. Once adjusted, you should be able to access the Limit 8 M4 using the new IP address implemented.
