ATM18 Catches the RS-485 Bus

Next stop for driving relays…

Published in issue 412, April 2011

If you’re looking to establish communications between two electronic boards via a wired link over a distance of over 1 km, with no intermediate active elements, then there’s really only one solution: an RS-422 link. And if you want to link three boards, then the point-to-point link becomes a multi-point link, and you’ll need an RS-485 bus.
