I purchased this adapter to parameterize devices in industrial environments which require a RS485 interface for parameterization. The RS232 / RS485 adapter used previously worked with a USB / RS232 (serial) adapter together under certain conditions, also an external power supply (AC adapter) for the RS485 was necessary. The acquired adapter is based of course on a virtual COM port, combining funktionier previously but with devices from different manufacturers without any problems. As a special advantage, I feel that I no longer need the external power supply since the adapter provides the RS485 from the USB power out. One point deduction is available for the lack of documentation, this I have found only after consultation with the manufacturer on the website of the company in the local shop. In addition, no switches or screw is labeled on the casing - a little sticker would be very helpful here.
