Oh, OK, what you want is to synchronize a stand-alone indexer with
a non-configurable CNC control. What you can do is take one of
the auxilliary control outputs (like mist coolant on) and tie that to the
'go' button on the indexer. Then, whenever the program calls for
mist on/mist off, it will cause the indexer to perform the advance it
was set for.
