Squarewave,
While, we do offer RS232 controllers, we do not recommend the DMC 1500 for CNC use, because it is too slow and has been discontinued by Galil years ago.
We also offer a variety of models for EtherNet, as well as what Al mentioned the PCI and ISA versions.
Take a look at these plus the low end 4 axes RS232 DSP based motion board at:
