Console Port and Auxiliary Port Connection Guidelines
The RP has two EIA/TIA-232 (formerly RS232) serial RJ-45 connection ports:
• Console port—RJ-45 interface for connecting a data terminal device to the router, which you need to
• Auxiliary port—RJ-45 interface for connecting a modem.
Note The console and auxiliary ports are asynchronous serial ports. Ensure that devices connected to these ports
are capable of asynchronous transmission.

Console Port Signals

The RP console port is an RJ-45 interface for connecting a terminal to the router. The console port does not
support modem control or hardware flow control and requires a straight-through RJ-45 cable.
Before connecting a terminal to the console port, check the terminal setting for the data transmission rate, in
bits per second (bps). The terminal transmission rate setting must match the default rate of the RP console
port, which is 115200 bps. Set the terminal to these operational values: 115200 bps, 8 data bits, no parity, 1
stop bits (115200 8N1).
The following table lists the signals used on the RP console port.

etc through USB disk. Also, it can be used to transfer
router log from the internal eUSB to the external
memory stick. Signal type is NRZI.
For Cascading two Cisco ASR 9001 Router systems.
