I bought a couple of these units to test Modcom RTU communications over an RS485 bus in a solar farm installation using Modscan and Modsim software with PV Powered inverter interfaces and Watts-on transducers. They work good for 2 wire. They dont have 4 wire capability. When I tested them between two laptops I had to turn off the terminators and not use the ground wire. In the field, I had to turn off the terminators, but use the ground wire. Also note the older version Windows drivers worked, but the newer drivers on the Startech.com website did not. Not sure why that was the case, but for my test bed the older drivers worked.
