Yes, but you do need to use LinuxCNC 2.5 to support the 7I48 a 5I25/7I77 might be a better solution if you need additional 12/24V I/O > 2.

Its a little awkward with 7 but for example: The 7I52S has 6 RS-422 step/dir outputs and 6 RS-422/TTL encoder inputs so 2 of these would give 12 of each. This would require a 5I23 as this is too much logic for a 5I20. This requires LinuxCNC 2.5 as well 2 7I47s would also do, giving 8 encoder inputs (RS-422 only) and 12 RS-422 step/dir outputs. > > Thanks, > Andrew > ------------------------------------------------------------------------------ > Keep Your Developer Skills Current with LearnDevNow! > The most comprehensive online learning library for Microsoft developers > is just $99.99!
