All Things A/V

Welcome to the largest known collection of RS-232 and other protocol information for audio/video and related equipment. This is a useful resource for professional control systems programmers (working with such systems as Crestron or AMX), systems integrators, hobbyists, and equipment owners.

Please be patient as we add content from our collection to the public web server. This process is starting at the beginning of the alphabet and progressing forward. We hope to have this process complete soon. Manufacturers that are listed below without a link are not yet available online.

Submissions and Requests

In order to provide the highest quality RS-232 documentation, all content on this site is reviewed before being posted. If you have a document you would like to see added to the collection, please . Do not submit documentation that you have entered a legal agreement not to distribute. If there is a document you are looking for that is not available here, please and we will see if we can track it down for you.
