Hi all I'm looking to get two systems on isolated power setups talking over serial. Doesn't need to be high baud or anything. Would an optocoupler setup be the way to go for this, and if so, are there any particular models or characteristics I should look at? Thanks Olly

Serial via optocoupler?

Sounds like just about any opto would work for this.

By "serial" do you mean 5v or RS-232?
