I’m using rs422 to connect to a very old legacy system. The other comments where people say this doesn’t work are wrong. It’s their lack of understanding how computers and electronics work.
Firstly, the driver is ftdi. By default this should work plug and play with windows 10+ and Linux. If it doesn’t, just download the correct ftdi driver for your operating system.
Second, people saying the signal is too weak and such… ugh, it’s because they don’t have the gnd connected. I get it, the schematics don’t display a common gnd, so people don’t bother. But you need a common gnd on all electronics. It’s how each device can reference voltage! The schematics didn’t display it because it’s common sense.
Carbon emissions from the lifecycle of this product were measured, reduced and offset.
