ETHERNET: Connect the unit to the network permanently with RJ45-RJ45 "straight through" (not
2
"crossover") networking cable. Use cable suited to the network type, e.g. 10/100 base-T (most home
networks). This allows the unit to be plugged into a computer network, and is strongly recommended
where a wired connection is already available or can be installed. Standard UTP RJ45 networking
cable should be used to connect the unit to the networking router.
