Mesa 7i92 board config with BOB

    Hi, I bought a new Mesa 7i92 board and have made all the connections all the stepgen x ,y, z
moving correct but the output and input pins not workingCan someone help me with that. 

That BOB needs 2 power supplies, and the optos are slow.

The BOB is powered with 5v 
all the Stepgen are moving but the input and output not working. 

 

Like Tommy said you need 2 supplies, I think you need a field supply between GND and VDD.

I have changed the board but still.

Again, this also requires 2 power supplies.
You should really read the manuals, although they are usually not much help being China cr@...

I have powered the board with two power
the Green LED is 12v and the Red LED is 5v and the 7i92 also have been powered with 5v.

How did you check the inputs?

I think the second bob inputs are activated by grounding them

Both BOB seem to require short to ground.
Make a simple config using StepConf, just so you can start Axis GUI with it, then on the "machine" menu click on "show hal configuration", there on the left side click on "pins" then "parport",
On the right side click on the "show" tab,
On the left side click on the 10 in, 11 in, 12 in, 13 in, 15 in,
Now on the right side you can see the LED change color when you short an input to GND on the BOB.
