CONNECTING THE LAN (ETHERNET) INTERFACE
The RJ-45 port labeled “LAN” is the 10/100BaseT/TX interface. This port is designed to
connect directly to a 10/100BaseT/TX network. Figures 6 & 7 show the signal/pin
relationships on this interface. You may connect this port to another Ethernet device via
a Cat 3 or Cat 5 cable that is up to 328 ft long.

Connecting the LAN (10/100BaseT/TX) Ethernet Port to a Hub
The XC300NT 10/100BaseT/TX interface is configured as DTE (Data Terminal
Equipment), just like a 10/100BaseT/TX network interface card in a PC. Therefore, it
"expects" to connect to a DCE (Data Communications Equipment) device such as a
Hub. This typically uses a straight-through cable. The Figure 8 diagram shows the cable
wiring for connecting the XC300NT to a 10/100BaseT/TX hub.
