15. Connect the other end of the RS-232C cable to your computer's RS-232C port.

RS-232C interface cable

The RS-232C port on your newly installed RS-232C interface has a DB-25 (standard 25-pin serial) female
receptacle, which accepts a male DB-25 cable plug. Your computer's port may have either a DB-25 or DB-
9 (9-pin) receptacle.
If necessary, see the chart below for detailed information on the pin assignment for your fax machine's
RS232C port.
Note: For more information on the computer's serial interface port, see the computer's operating
instructions.
Note: Please use an RS-232C interface cable that is shorter than 3 meters.
