For 7737, you can still use it to command motion to the drives without the encoder feedback.  you don't need the closed-loop activation to send the pulse train to the drives.  The signals available on RJ45 are drive enable, drive alarm, step+/-, Dir+/-, 5v, Gnd, 24v.

Hi Overcooked,
Nice to see someone admit that they didn't know everything.

They guys from Vital are great to work with which is why I have been a happy user all these years.

lol thanks. this isnt the first of the last time that will happen!

ya i realize that, i just didn't see the need to integrate it (7737) at this point because i couldn't really use the added functionality that board offered. plus i didnt have the RJ45 cables made up.

But i found all the connectors, cat 6 cable and the crimp gun, wired the drives and encoders into the 7737 and the motors still jog back and forth. =]

but the encoders dont seem to be being picked up by the 7737.

do i need the activation to see the encoders at all? am i looking in the wrong place? or is this another example of my lack of knowledge...  ;D
i had one wired up to the smoothstepper so i have some idea that wiring/encoder is good.

once again, thanks!

without closed-loop activation the encoders 3 thru 8 wont work.  Encoder 0, 1, and 2 are always operational.  you will need the activation to be able to use them for closed-loop control.
