Console Port Pin Assignments

The DB-9 DCE serial port on the front panel of the SMC2555W-AG is used to connect to the access point for out-of-band console configuration. The on-board menu-driven configuration program can be accessed from a terminal, or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following tables.

Wiring Map for Serial Cable

Signal (serial port)	Pin	Signal (management console port)

GND (ground)	5	GND (ground)
Unused	6	Unused
CTS (clear to send)	7	RTS (request to send)
RTS (request to send)	8	CTS (clear to send)

Note: The left hand column pin assignments are for the female DB-9 connector on the access point. Pin 2 (TXD or “transmit data”) must emerge on the management console’s end of the connection as RXD (“receive data”). Pin 7 (CTS or “clear to send”) must emerge on the management console’s end of the connection as RTS (“request to send”).
