UCSB board setup

[Vmax549]

I am setting up a new UCSB bob to be used for encoders and probes (tool probe and spindle probe) . I don't see any examples for encoder hookups. Also all the inputs seemed to be either 12v or 24v hookups . Are there any 5v senarios for the inputs like for probes and 5v MPGs and 5v spindle encoders etc. All the stuff I plan to add came from a LPT setup (mach3, spindle encoder, MPG,touch probe , tool probe,etc).

UCSB also works with 5V. Common the I- inputs to GND and connect the encoder outputs to I+ inputs. If it doesn't work then connect the I+ inputs to the same 5V as the encoder and the encoder outputs to the I- inputs.

OK when you say common the i- to ground did you mean earth ground or 0v (common) ??

Sorry, 0V is written on the board.

It depends on the encoder outputs. If they are NPN or PNP or line driver, there are drawings for all there type of outputs in the UCSB manual.
If it is TTL buffer output then you can connect it as NPN or PNP, then both connection diagram will work.

Can you tell me what the max speed of a spindle encoder would be using a 100 count encoder ??

It is about 50kHz, 50000Hz, so 50000/100*60=30000 RPM (1/min)
