Console Port Signals - Cisco 7206 - VXR Router Installation Manual

Chapter 3 Installing the Cisco 7206
Connecting I/O Controller Cables
Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports
Note
must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device;
for example, most modems are asynchronous devices.)
Before connecting a terminal to the console port, configure the terminal to match the router console port
as follows: 9600 baud, 8 data bits, no parity, 2 stop bits (9600 8N2). You need an EIA/TIA-232 DCE
console cable to connect the terminal to the console port. After you establish normal router operation,
you can disconnect the terminal.
You must supply your own interface cable between the auxiliary port and the equipment you are
connecting. For console and auxiliary port pinouts, refer to the following sections "Console Port
Signals" and "Auxiliary Port Signals."

Console Port Signals

Table 3-1 lists the signals used on the console port. The console port does not support modem control or
hardware flow control. Both Data Set ready (DSR) and Data Carrier Detect (DCD) signals are active
when the system is running. The Request To Send (RTS) signal tracks the state of the Clear to Send
(CTS) input. The console port requires a straight-through EIA/TIA-232 cable.
