Well... sort of One of the 7I90 firmware options is to run as a simple (72 DIO) sserial remote The processor code for the remote is part of the hostmot2 firmware source (in ssremote.zip) Its written in a quite obscure assy language. but _might_ be somewhat comprehensible if combined with the sserial protocol description thats in the back of all sserial remote manuals > _______________________________________________ > Emc-developers mailing list > Emc-developers@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-developers > Peter Wallace Mesa Electronics ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
