Console and Auxiliary Signals

You can configure the console interface by using Cisco IOS command line interface (CLI) commands.
The console interface and the AUX port can be accessed simultaneously. Also, the console port and the
AUX port can be accessed simultaneously. For example, you can connect a terminal to the console
interface and an external modem or a GPS modem to the AUX port.
The console port signals are provided through the multifunction header:
•
•
•
The AUX port is a serial asynchronous port that works at speeds of 1.2 kbps, 2.4 kbps, 4.8 kbps,
9.6 kbps, 19.2 kbps, 38.4 kbps, 57.6 kbps, and 115.2 kbps.
The AUX port supports the following:
•
•
•
•
•
•
When zeroization is enabled, it is activated through the polling of pin 25 on the AUX port.
Note
A +5-V power supply is provided for a device connected to an AUX port. Typically the +5-V power
supply current to GPS modems should be limited to less than 200 mA.
