Serial port connections

The diagram below shows the types of serial connections supported by the ports at the rear of the NION.

The NION RS-232 serial port performs two main functions:

• In console mode it allows a user to log on to the NION Linux Kernel via a serial terminal session and change the configuration settings.
• When console mode is disabled, you can control the NION using external protocols like PASHA.

By default, console mode on the NION RS-232 serial port is disabled.

The RS-485 serial port can be used to communicate with external devices in the same way as the RS-232 port, and using the same protocols, but cannot be used for serial terminal connections to the NION.
