GDI XC300 Owner's Manual page 10

The XC300LT 10/100BaseT/TX interface is configured as DCE (Data Communications
Equipment), just like a 10/100BaseT/TX network hub. Therefore, it "expects" to connect
to a DTE (Data Terminal Equipment) device such as a PC. This typically uses a
crossover cable. The Figure 9 diagram shows the cable wiring for connecting the
XC300LT to a 10/100BaseT/TX hub.

Connecting the LAN (10/100BaseT/TX) Ethernet Port to a PC (DTE)
The XC300 LAN (10/100Base-T) interface is configured as DTE (Data Terminal
Equipment). If you wish to connect the XC300 to another DTE device such as network
interface card (NIC) in a PC (or XC300 in a back-to-back arrangement), you must use a
crossover cable as shown in Figure 9.
XC300LT LAN (10/100BaseT/TX) Port
NOTE: When connecting to a 10/100BaseT/TX Switch that is equipped with crossover
detection it is not necessary to use a crossover cable from the XC300LT to the switch.
The need to crossover will be automatically detected within the switch and the
connection will be made.
