The RS232 serial cable connects the Microrouter to the PC port labelled COM 2. The RS232 cable is the long, thin cable fitted with a 9 pin D female
connector at one end and a 25 pin D male connector at the opposite end. Connect the 25 pin D male end of the RS 232 cable to the 25 pin D female
RS 232 port on the righthand side panel of the Microrouter. Connect the remaining 9 pin D female end of the RS 232 cable to the 9 pin D male COM2
port on your PC. Note - a 9 pin to 25 pin adapter may also be required if your COM port has a 25 pin connection.

PC Terminology: The COM ports on your
PC may be labelled as Serial ports. Most
COM ports have a 9 pin D MALE
connector, though some older computers
may be fitted with 25 pin D MALE
connectors. The Parallel port on your PC
may be labelled as the Printer port. The
printer port has a 25 pin FEMALE
connector.
