How does the HAH attach to my home internet connection.

The HAH just plugs into a spare port on your internet router (using a standard RJ45 network patch cable). The HAH uses the DHCP server on the router to acquire an IP address. If you have fitted the optional LCD to your HAH, the IP address assigned to the HAH, by your internet router, will be shown on power up. After that, the LCD is fully addressable via xAP for displaying any text that you want.

Note that you generally can't use a Cat5 cable to connect your HAH directly to a network card on the back of your PC or laptop.
