You will need to lookup your network's information such as default gateway and subnet mask if you are looking to assign a static IP address to your device. Otherwise you can use DHCP. Make sure your 100C is properly connected to your network. Then follow these steps:
Access Admin Settings
Press and hold the M/OK button for a few seconds. If the device displays an Admin Affirm message along with a padlock icon, an admin must place their finger on the scanner to authenticate.
Navigate to Network Settings
Enable/Disable DHCP
Set Web Server Mode
Reboot the Device
Then login to AMG and enter the device into the software.
