Why is Indexer LPT sold separately from G Code Controller and HPGL Controller?
This modular approach gives machine designers the greatest measure of flexibility. Since all external sensing and control occurs through Indexer LPT, and access into Indexer LPT is clearly defined, application programs can be easily interchanged. The “Pictures” section of this web site shows examples of machinery that use application programs written by Ability Systems (G Code Controller, HPGL Controller) and others. In some cases, different application programs can be run on the very same machine, depending on the needs of the job at hand.
