Asynchronous Serial Ports

Figure D-7 shows the RJ-45 breakout cable with pinouts for the 68-pin SCSI port and the RJ-45 serial port. Table D-14 contains the pinout for the RJ-45 end, and Table D-15 contains the pinout for the 68-pin SCSI type connector.

Table D-14. Asynchronous Breakout Cable Pinout (8-Pin RJ-45)

8 Pin RJ-45	Signal	Direction
1	CTS
2	DSR/DCD
3	RXD
4	RXD/GND	-
5	TXD/GND	-
6	TXD
7	DTR
8	RTS

NOTE

The Asynchronous breakout cable is equivalent to a console or auxiliary port with a roll-over RJ-45 cable attached. See Table D-17 for asynchronous device connection options.
