"Pin assignments: 8691omSF module Management port" (page 130) shows the pin assignments for this connector.

Pin assignments: 8691omSF module Management port

Connector	Pin number	Signal
	1	Output transmit data + (TX+)
	2	Output transmit data - (TX-)
	3	Input receive data + (RX+)
	6	Input receive data - (RX-)
	4, 5, 7, 8	Not used

Console serial port

The Console serial port is implemented as a DB-9 connector. This port can operate as a data terminal equipment (DTE) or data communication equipment (DCE) device. Use the switch to the left of the port to set the port to DTE (right) or DCE (left). Default settings for this port are 9600 bits/s, 8 data bits, no parity, and one stop bit.

Connection to TXD and RXD signals and GND is sufficient for the console serial port to fully function. The Console port does not support any inbound flow control; that is, the port does not toggle control lines to indicate an input buffer full condition.

"Pin assignments: 8691omSF module Console port" (page 130) lists the pin assignments for the Console port for both the DTE and DCE settings.

Pin assignments: 8691omSF module Console port

Connector	Pin number		Switch position
		DCE (left)		DTE right)
	2	TXD (Output)		RXD (Input)
	3	RXD (Input)		TXD (Output)
	4	DSR (Input)		DTR (Output)
	5	GND		GND
	6	DTR (Output)		DSR (Input)
	7	CTS (Input)		RTS (Output)
	8	RTS (Output)		CTS (Input)

Modem serial port

The Modem serial port is implemented on a DB-9 connector wired as a DTE connection.
