RS485 must be connected opposite to the polarity marked on the breakout board. The yellow trace is connected to T/R- which is connected to the + pin in the transmitter. It does not work if connected as labeled.I don't know if they are swapped on the DB9 or the breakout board.

I opened the package, plugged the USB cable into my Windows 10 machine, and viola! Windows found the drivers and behold I had a COM port listing for the adapter. With a terminal program I was instantly transmitting and receiving. I uses it for experimental work with microcontrollers. As one reviewer mentioned, the lights blur into each other. I might try his trick to open the case and put heat shrink tubing over the sides of the LEDs, but really not a big deal, anyhow.

Needed to test an ASCII laser sensor before connecting to PLC. The sensor required a separate 24V power supply in addition to RS422 4-wire connections. Device worked perfectly, the RX\TX light indicators were very useful when first connecting the device to determine correct wiring; the labelled terminals also a nice sanity check. No problem installing the drivers in windows 10 1809.
