Ethernet
HUBBCOM smart controllers have dual Ethernet ports. Use the RJ45 jack furthest from the USB port to
connect to the Ethernet network. The RJ45 jack closest to the USB port can be used to connect a PC.
1.
Plug the Ethernet cable from the network into the RJ45 jack furthest from the USB port.
2.
Install a clamp on ferrite core as close as possible to the RJ45 plug.
3.
(Optional) Plug an Ethernet cable from a PC into the remaining RJ45 jack.
