Overview of the serial console Direct link to this section

The serial console is an interface that allows you to restart or reconfigure an appliance when you connect to it using a cable or AirConsole adapter. This is typically used for troubleshooting when other methods do not work.

This is typically used for troubleshooting when:

• Other configuration methods do not work.
• You are configuring an appliance to use a proxy server.

This page describes the hardware requirements for the serial console, as well as how to use the serial console.

Requirements Direct link to this section

This section details the hardware and driver requirements to use the serial console for each model.

Hardware requirements Direct link to this section

These are the hardware requirements for serial console sessions:

Install the required drivers Direct link to this section

This section guides you through the installation of required drivers to use the serial console.

AWN101 serial console session driver Direct link to this section

To install the required driver for the AWN101 sensor:

1. If you are using a Mac, and this Mac was previously used for another console session, run this command in a terminal to uninstall the previously installed driver:

   sudo rm -rf /System/Library/Extensions/ProlificUsbSerial.kext

2. Download the driver from Prolific, and install it.

   Note: macOS requires approval before installation. You are prompted to enter your password during the installation.

3. Use the cable identified in Hardware requirements to connect the sensor and your computer.

Console session drivers for all other appliances Direct link to this section

To install the required driver on all other appliance models:

1. Use the cable identified in Hardware requirements to connect the appliance to your computer.

2. In a terminal, run the following command to identify the serial device name:

   ls /dev/tty* | grep -i usb

   This may return multiple USB device names for the computer.

3. Run the following command, where <usb_serial_device> is one of the serial USB device names from the previous step:

   sudo screen /dev/<usb_serial_device> 115200

   For example, for Linux, you might enter sudo screen /dev/ttyUSB0 115200.

AirConsole requirements Direct link to this section

AirConsole is a portable, battery powered RS232 serial port over WiFi or a Bluetooth adapter. If you cannot use a physical cable, and you own an AirConsole adapter, you can use it instead.

For AirConsole, you need the:

• AirConsole adapter
• IP or hostname address of the AirConsole adapter
• AirConsole driver downloaded and installed

To connect AirConsole:

1. Launch the AirConsoleOSX application on your Mac.
2. Change AirConsole from Auto to Manual.
3. Enter the hostname of the AirConsole. For example, aircon1.
4. Connect to the AirConsole device with this command, where <serial_number> is the serial number of the device:

   sudo screen /dev/cu.Airconsole-1 <serial_number>
