Connecting to a Console Terminal or Modem
Console Port Connections
The router has an EIA/TIA-232 asynchronous serial console port (RJ-45). Depending on the cable and
the adapter used, this port will appear as a DTE or DCE device at the end of the cable.
Your router is supplied with an RJ-45-to-DB-9 adapter cable for connecting to a PC that is running
terminal emulation software.
To connect the router to an ASCII terminal, use the RJ-45-to-DB-9 cable and a DB-9-to-DB-25 adapter.
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 on page 4-5.
For cable and port pinouts, see the online document Cisco Modular Access Router Cable Specifications.

Connecting to the Console Port
If a console terminal or PC is connected to the console port, you can configure the router locally. Follow
these steps to connect a console terminal or PC that is running HyperTerminal or similar terminal
emulation software to the console port on the router:
Step 1 Use the blue RJ-45-to-DB-9 console cable to connect the router to a terminal.
Note On the Cisco 1800 series fixed-configuration routers, the console port is color-coded blue.
Step 2 Configure your terminal or terminal emulation software for 9600 baud (default), 8 data bits, 1 stop bit,
and no parity; set flow control to “none.”
Note Because hardware flow control is not supported on the console port, do not connect modems to
the console port. Connect modems only to the auxiliary port.
Auxiliary Port Connections
The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control.
Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the
cable.
Your router is supplied with a DB-9-to-DB-25 adapter for connecting to a modem.
For detailed information about connecting devices to the auxiliary port, see the “Connecting to a Console
Terminal or Modem” section on page 4-5.
For cable and port pinouts, see the Cisco Modular Access Router Cable Specifications online document
on Cisco.com.
