BloxOsLite (UbiSwitch, SwitchBlox Industrial)

Physical UART Connection

The CLI is accessed using the UART port on the SwitchBlox Industrial. The UART port is typically connected to another UART port on a management PC, or to a USB port on a management PC through a UART to USB converter.

This following pins on the UbiSwitch Module are used for the UART port.

USART_RX (input to module)

USART_TX (output from module)

The ground reference must also be connected to the UART device. Any of the ground pins on the board module can be used for this.

<aside> ⚠️ Note that the UART connection is not isolated, thus from the main ground on board. Therefore, make sure board and the connected UART device share the same ground. You can get around this limitation by using a isolated line driver or isolated UART to USB converter.

</aside>

Extension header shows UART TX, RX along with 3.3V and GND lines.

CLI Bringup

Follow the steps below to access the CLI on SwitchBlox Industrial
