Flasher Hub - UART Port

Example setup using Flasher Hub's UART Port

UART Port, formerly known as "UART Transceiver", is a feature of Flasher Hub-12 that makes it possible to communicate with a target UART.

Usage

The UART Port can be used to communicate with a target UART for e.g.

1. Running tests on the target after it was programmed
2. Writing and reading calibration data on the target after it was programmed
3. ...

A typical workflow that uses the UART Port looks as follows:

1. Make sure the UART Port feature is active
2. Configure and enable the UART Port for the desired module position
   • This can be done via the terminal (see #TERMINAL command) or the web interface
3. Open a TCP/IP connection to the UART Port
4. Data sent to the UART Port via TCP/IP is forwarded to the target UART
5. Data sent by the target UART is forwarded via TC/IP to the connected client

Configuration

Flasher Hub web interface UART page

The UART Port feature can be activated using the Config → Flasher Hub page of the web interface. The base port setting determines the port numbers that Flasher Hub will open for its modules:

Module UART Port number = Base port + Module position

For the default base port (2000), the following ports result:

Module position	UART Port number
1	2001
2	2002
3	2001
[...]	[...]
24	2024

Once the UART Port feature is active, UART Ports for selected modules can be enabled using

• the UART page of the web interface or
• the terminal command #TERMINAL

UART Settings

The following list of parameters can be configured for a module's UART Port:

• Baudrate
• Number of data bits
• Parity
• Number of stop bits

Connection

An example configuration for connecting to Flasher Hub's UART Port using PuTTY as TCP/IP client application

Once a modules' UART Port is enabled, a TCP/IP client can connect to it by opening a raw connection to Flasher Hub's IP address and the respective UART Port number.
Both are displayed on the UART page of the web interface for convenience.
