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. Figure 3 shows 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 XC-NT200 LAN interface is configured as DCE (Data Communications
Equipment), just like a 10/100BaseT/TX network hub or a switch. Therefore, it
"expects" to connect to a DTE (Data Terminal Equipment) device such as a PC
or a router. When connecting to a DTE it typically uses a straight through cable
as shown in figure 4 below.
