Console Port Connections
Console Port Connections
The C111x has both EIA/TIA-232 asynchronous (RJ-45) and USB 5-pin micro Type B, 2.0 compliant serial
console ports. The console ports do not have any hardware flow control. Shielded USB cables with properly
terminated shields are recommended.
EIA/TIA-232
Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the
cable. Only one port can be used at the same time.
The default parameters for the console port are 9600 baud, 8 data bits, 1 stop bit, and no parity. The console
port does not support hardware flow control. For detailed information about installing a console terminal, see
the Connecting to a Console Terminal or Modem section.
For cable and port pinouts, see the Cisco Modular Access Router Cable Specifications document located on
Cisco.com.
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
micro USB Type-B cable. The USB Console supports full speed (12Mb/s) operation. The console port does
not support hardware flow control.
Note
Always use shielded USB cables with a properly terminated shield.
The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. For detailed
information about installing a console terminal, see the Connecting to a Console Terminal or Modem section
on page 3-19.
For operation with a Microsoft Windows OS version older than Windows 7, the Cisco Windows USB Console
Driver must be installed on any PC connected to the console port. If the driver 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, and 115200 bps.
Note
4- pin micro USB Type-B connectors are easily confused with 5-pin micro USB Type-B connectors. Only
the 5-pin micro USB Type-B is supported.
