Re: [Emc-users] Fiber optic control for CNC

Fiber optics is not hard to use. One of the easiest systems is the one used for audio cables in your TV set and stereo. they call it Toslink digital audio or S/PDIF. You buy the cables with ends attached at Best Buy or way-cheeper at monoprice.com Using a consumer cable makes it easy to buy

Re: [Emc-users] Fiber optic control for CNC

Yes. The linked device acts just like 1/2 of a 3.3 volt opto isolator. However there are devices LIKE it that cost 1/10 as much, run on 5 volts are faster and use consumer grade cables. But the ability to use un-terminated fiber cable cut from a bulk spool. It is worth paying more for that.

Could something like https://www.digikey.com/catalog/en/partgroup/afbr-1528cz/66628 be useful? They are about $12 each but operate at 5Mbps so perhaps you could multiplex some of the signals. There is also an eval kit https://www.digikey.com/products/en/development-boards-kits-programmers/eval

The stuff is good to about 350C and completely resistant to oils and solvents. It is used as a single layer roofing material in clerical buildings and as a high performance gasket in high pressure and temperature applications.It would be complete overkill to use fiber reenforced hypalon for a

Re: [Emc-users] Fiber optic control for CNC

Leadshine drives input/output are not just opto, they're differential. i.e. the step signal has 2 wires and dir has 2 wires, there's no common ground or common anode. So they're not just galvoisolated from the pulse source, but from each other. When run as twisted pairs or just pairs, the
