What you need
Your Qscan will connect to power and the internet using POE (power over ethernet).
One ethernet cable will run from your router to your POE device. The second cable will run from the POE device to your Qscan. Each Qscan should come with a tan ethernet adapter into which you will plug the second ethernet cable running from the POE device.
The Ethernet cables should be CAT6 to ensure a reliable connection. "CAT6" is the type of cable.
