[time-nuts] Re: timing lab, remote control

ooh.. $500 each.. That's about what I would expect, but you gave the key thing, a search term.

This kind of need is pretty common in the PLC/industrial automation world.

Moxa among others makes devices like this.

The search term you're looking for is "IO mirror"
