N-Tron 102PC-SE - Manual (Page 12)

CONNECTING THE UNIT
For DCE serial devices (like a modem) use a null modem RS-232 cable to connect to the 102PC-SE. For a
DTE serial device (like a computer) use a straight through RS-232 cable.
For the 10/100 Base-TX port, plug a Category 5E twisted pair cable into the RJ45 connector. Connect the
other end to a PC or a network through a hub or switch. A standard straight through or cross-over Category
5E cable may be used to connect to either device. The MDIX mode of the 102PC-SE can be changed using
jumper J1 on the board. By factory default the device is set up to use a straight through cable for a PC. Any
N-Tron switch will automatically determine what MDIX the 102PC-SE is using and will connect it to the
network.
