Basic but functional.

The converter works as expected; Driver installation is usually not necessary, but if they do, there's at FTDI the latest downloads. By dissolved by hardware transmit enable control and no hardware handshake is required. The unusually also dissolved in hardware echo cancellation could possibly, result in software that expects the echo irritation - but has not yet come across me. The plug connector is completely oversized for the purpose, but of course functional when one considers that the wires to be connected shall not be thinner than 0.5 mm, because they are clamped otherwise incorrect.

However, the designer has the USB / serial part by jumpers from the serial / RS-485 part separately or made separable. So far so good ... but unfortunately runs between the 4 jumpers a fifth connection to enable control of the RS-485 chips, which is barely visible through the paint the board. Who believes now, to electrically disconnect the RS-485 transmitter by pulling the jumper, toasting with the smallest common-mode voltage to the one or both still connected logic pins!
Whoever wants to exclude any (additional) risk, should place the GND jumper soldering a bridge.

The price is ok, the delivery speed was sensational. So who knows, will not be disappointed with this part.
