Console and Auxiliary Port Considerations
• USB Serial Console, page 3-2
EIA/TIA-232 Port
Depending on the cable and the adapter used, this port will appear as a data terminal equipment (DTE)
or data communications equipment (DCE) device at the end of the cable.
For connection to a PC running terminal emulation software, your router is provided with an
RJ-45-to-DB-9 cable.
To connect the router to an ASCII terminal, use the RJ-45-to-DB-9 cable and a DB-9-to-DB-25 adapter
(provided).
The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The
console port does not support mode control. For detailed information about installing a console terminal,
see the “Connecting to the Console Port with Microsoft Windows” section on page 4-14.
For cable and port pinouts, refer to Cisco Modular Access Router Cable Specifications.
USB Serial Console
The USB serial console port connects directly to the USB connector of a PC using a USB Type A to 5-pin
mini Type-B cable. The USB Console supports full speed (12Mb/s) operation. The console port does not
support hardware flow control.
The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The
console port does not support mode control. For detailed information about installing a console terminal,
see the “Connecting to the Console Port with Microsoft Windows” section on page 4-14.
For operation with Microsoft Windows, the Cisco Windows USB Console Driver must be installed on
any PC connected to the Console port. If it is not installed, prompts guide you through a simple
installation process.
The Cisco Windows USB Console Driver allows plugging and unplugging the USB cable from the
console port without affecting Windows HyperTerminal operations. No special drivers are needed for
Mac OS X or Linux.
Only one console port can be active at a time. When a cable is plugged into the USB console port the
RJ 45 port becomes inactive. Conversely, when the USB cable is removed from the USB port the RJ 45
port becomes active.
Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 bps.
Note 4-pin mini Type-B connectors are easily confused with 5-pin mini Type-B connectors. They are not
compatible Only the 5-pin mini Type-B can be used.
