Hi,
not as far as I know. The only indicator of activity on the USB link is the LED on the UC100. Of course you can't tell what its sending just that it is.

Jog back and forth, and measure the voltage at the direction pin. It should toggle between 0V and 5V, depending on direction. If the blue led on the UC100 is lit, and the DRO's are changing on the screen when you jog, then it should be sending data.

Are your motors locked up?

I see no power at all on direction pins when jogging.  The blue light is lit on the UC100 and the DRO's are changing.  The motor turns free with the power off but is tight when turned on.  I have no voltage on the PV5V terminals on the ST-V2 breakout board.  Does this power come from the computer.  Thanks.

Do you have the USB cable plugged in to the breakout board?

You need that, and you also need a 12V-24V power supply, or the inputs won't work.

I have the usb cable plugged into the back of the UC100 and it is plugged into the breakout board.  I also have a 15V power supply plugged into it.  Can I remove the UC100 and check to see if one of the pins is providing the 5V power

Hi,
I don't think the UC100 is meant to provide power to your breakout board. Sounds like you need a USB cable from the
PC to the breakout board to provide power to the board AND a 12-24V supply for the board as well.

Yes, the breakout board won't work unless you plug the USB cable into it for 5V power.

Plugged in usb from computer to breakout board.  I now have 5 volts on the breakout board and going to the motor driver inputs.  Still no motor activity when I try to jog.  I don't get any voltage on the direction pins on the driver when I try to jog.  I must have this thing really screwed up.  Can you provide any more direction on what I can try.  Thanks

Hi,
I believe your breakout board requires TWO power supplies. One you already have in place with the USB from the PC. You require a second
12-24V supply for the opto isolated outputs.
