Cisco Systems 1200 manual Console Port Signals and Pinouts, Txd Rxd Gnd

Appendix E Console Cable Pinouts

Overview

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.

Note When your configuration changes are completed, you must remove the serial cable from the access point.

Table E-1lists the signals and pinouts for the console RJ-45 to DB-9 serial cable.
