Hardware Reference Guide - NX-Series NetLinx Integrated Controllers
LAN 10/100 Port
All NX-series controllers feature a LAN 10/100 port to provide 10/100 Mbps communication via Category cable. This is
an Auto MDI/MDI-X enabled port, which allows you to use either straight-through or crossover Ethernet cables. The
port support IPv4 and IPv6 networks, as well as HTTP, HTTPS, Telnet, and FTP.
The LAN port automatically negotiates the connection speed (10 Mbps or 100 Mbps), and whether to use half duplex or
full duplex mode.
FIG. 35 displays the LAN port for the NX-series controllers.
