    Hi Bob,

    In my opinion, RS485 is the way to go. It's very simple, and cheap to setup. Have a master that polls each node, and waits for the report. You can easily setup a dedicated node for controlling a display as well.

    Here's an example of how easy this is with a BASIC Stamp.

    Jan Axelson's Serial Port Complete is one of the best books around on this subject. You can find them at most book stores, or online at amazon.com or our site http://www.rentron.com/Books/book2.htm

    Her website is at http://www.lvr.com and has a ton of links to related websites.
