SERIAL INTERFACE
The 102PC-SE provides an EIA-232 interface accessed via a 9 pin male connector (labeled ‘COM’ on the unit). This
is used to access the Command Line Interpreter (CLI), and to attach serial devices to the network over Ethernet. The
pin-outs are shown below:

Serial Cable
Connect the serial COM port of your PC and the 102PC-SE Protocol Converter using a standard straight through
cable. You will need a cable with a 9-pin or 25-pin sub-D female connector for the PC end (DTE device), and a 9-pin
female sub-D connector for the 102PC-SE end (DCE device).
The following table shows the pin-out and the connections for a straight through cable:
