Search The Fine Web

I put in exactly your search terms "mdb/icp protocol" to google. Looks like you can purchase the spec for $40.00. This was the 4th link in the list ...

You certainly can!
(not sure that it's still US$40, but that's definitely the place to go!)

I'm interested in the 2nd half of the question - the "Executive" (or "Protocol-A") interface.

Unfortunately, Googling for this just gets swamped in references to vending machines, coin-mechs, etc, that support "Exec" and I haven't yet found a proper specification.

I know that "Exec" was developed as a proprietary standard by Mars (MEI) - but is it now published anywhere? Or do I have to contact MEI?

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillatorhttps://www.avrfreaks.net/comment...

To answer my own question, for the benefit of anyone else who may be interested:

Yes, you need to contact MEI to request a copy of the document.
This can take a while, as their "support" site is well defended!

The full document details are:

TITLE: MEI 20 mA Protocol A Specification
NUMBER: 10102-000304001-PS
ISSUE: Y01
DATE: 10/2/95
COPYRIGHT (C) 1982-1995 MARS ELECTRONICS INTERNATIONAL

You can contact MEI via their website (eventually):
