How to use

If necessary, install any device drivers provided by the operating system or device manufacturer to enable communication. Verify the correct COM port assignment in your system settings or application before starting data transfer.

Recommendations

For reliable operation, use the cable for short connections (desk or bench setups) and avoid routing across high‑interference environments. Install the latest drivers from the device or OS vendor when prompted, and check that the serial communication parameters (baud rate, parity, data bits, stop bits) match between the PC and the connected device.
