I am trying to find a servo controller that can be sent commands over ethernet. To my surprise I cannot seem to find a nice simple one that will do this?! All I need to do is control 1 servo (if the device controls multiple servos that would be ok too).
If there is already an utp cable between point a and point b, there could be an other solution:
you could use the 4 wires that a normal pc network don’t need. Yes! There are too many cables in an utp cable. Its also used by people to power the router, and make a network connection over the same cable.
