Note: Circuits must tolerate voltages of + / - 15 V with respect to a ground reference and be able to withstand

indefinite short circuit to ground. Minimum outputs for the IR809 and IR829 are +/- 5 V.

RS232 Port

The RS232 signal names in

Serial 1 ports on the IR809 and IR829. It is the direction of the data and flow control signals that differs. The

RS232-DCE port, Serial 0, is designed to be connected to a far-end DTE port, or to another DCE port via a

crossover (null-modem) cable. The RS232-DTE port, Serial 1 is designed to be connected to a far-end DCE

port, or to another DTE port via a crossover (null-modem) cable.

CAUTION: please read the following three caution statements.

• This port is not shared with the Console port as is seen on some routers and switches in the Cisco Enterprise

• The pinout is also different from the connector pinout that was used for a Cisco RS232 console delivered

• Serial 0 and Serial 1 use EIA-561 standard for RS-232 signals on an RJ-45 style physical port. This

RS232 is Point to Point – DTE to DCE
