Hi Team,

As title, just a quick check.

Does GD75232 can support RS-422 protocol ?

I think the answer is No, right? It can only support RS-232.

Since RS232 is single end signal.

RS-422 / RS-485 are differential signal.

Thanks!

Kai,

That is correct, RS-422/RS-485 are differential signal schemes that require a specific physical interface. RS-232's physical interface does not match this.
