How to use
Connect the RS-232 connector of the adapter to the serial port of your device and plug the USB 2.0 end into an available USB port on your computer. Install the required driver if the operating system does not automatically recognise the adapter. After installation, configure the serial port parameters (baud rate, parity, data bits, stop bits and flow control) in your terminal or application to match the connected device.
Usage recommendations
 Use a stable USB port on the host computer and avoid USB hubs that may not provide consistent power or bandwidth. Verify and install the manufacturer-recommended driver for your operating system version. For reliable serial communication, match baud rate and flow control settings between devices and keep cable connections secure to prevent intermittent disconnection.
