This may sound a stupid question but I am new to playing with stepper motors and drivers. I am hoping someone can help with my query. Basically I bought some stepper driver boards off Fleebay. The drivers have 6 connectors for the outputs. These are:-

- Enable +
- Enable -
- Direction +
- Direction -
- Pulse +
- Pulse -

I only have 4 connectors on my breakout board, these are

XE - enable?
XD - direction
XS - Pulse/step
XN - Ground

Would I be right to assume the three negatives are linked together and then back to XN?
