Console Port Connector and Cables
The Cisco uBR924 router provides an RJ-45 serial connector for asynchronous serial console access.
The console port is a DCE device, so connecting it to another DTE device, such as the serial port on a
laptop PC, requires a straight-through DCE-to-DTE cable.
Table B-3 lists the pinouts for the console port and for the cabling required when connecting to a DTE
device that uses an RJ-45, DB-25, or DB-9 connector.
