whether or not you need a crossover cable depends on the ethernet adapter in you PC. Modern adapters don;t need a crossover cable, as they auto detect and do the switching internally. I don't use a crossover on either of my PC's.
Well I have the whole works on order I went with what info was given in the UC400 docs.    Cover is off the controller / PS box and voltage source located.  I am assuming since its pin for pin compatible with the parallel port all my present settings will work.   Zero documentation on configuring with Mach3/4 just about their own controller program.  So are you using 3 or 4 with your setup?   What pulse frequency?

Hi,
with an external motion controller you don't set the frequency.

You set the 'Steps Per', 'Velocity' and 'Acceleration' and the plugin takes care of the rest. Unless you have a really high precision (count) encoder running at high spoeed
the external controller will put out pulse no troubles.

You just install the plugin, set it as your motion device, and set the ports and pins. There's nothing else that's any different from using the parallel port, once you setup your network to see it, as described in the manual.

I have a UC300ETH, and have run it with Mach3, and UCCNC. I have the kernel speed at 200Khz, because I'm running servos with high encoder counts.

The Kernel speed is set in the plugin control window.

So the settings I have now will work as is? Does Mach3 know about the controller or is it a Plug In that is loaded on start up?

I can't say for sure. First thing you do is setup the network so the UC400 is recognized.
Then install the Mach3 plugin.
Then start Mach3.
If the UC400 is not detected, then you may need to go to Function Cfg > Reset Device Sel and restart Mach3. Then you can select the UC400 as your device.
You'll probably need to redo your motor tuning settings, due to the different kernel speed.

Ok I got it. Motor tuning I can undefstand, just as long as the basic ports and pins are the same, and they should be if its a clone of a parallel port pin for pin. Thanks for the help.
