“Nicly built, and at a reasonable price. One of the problems with RS485, is that it's not electrically isolated as standard. Ethernet (RJ45) is. There are plenty of low cost RS485 modules out there, but few of them are isolated, and those that are usually carry a high premium. So this was a nice find, and works great. Oh, and also nice to have a switchable terminator. Usually these are either absent or you have to get your soldering iron out. Top marks.”
