Overview Appendix C Console Cable Pinouts Overview The access point requires a special serial cable that connects the access point serial console port (RJ-45 connector) to your PC's COM port (DB-9 connector). This cable can be purchased from Cisco (part number AIR-CONCAB1200) or can be built using the pinouts in this appendix. Console Port Signals and Pinouts Use the console RJ-45 to DB-9 serial cable to connect the access point's console port to the COM port of your PC running a terminal emulation program. Note Both the Ethernet and console ports use RJ-45 connectors. Be careful to avoid accidently connecting the serial cable to the Ethernet port connector.
