Heidenhain ROD 426 encoder compatibility (Resolved)
Can anyone tell me if this encoder will be compatible with acorn board or will I need any additional hardwares?

Re: Heidenhain ROD 426 encoder compatibility
It should work just fine.
Key items are that it operates on 5VDC and produces a quadrature square wave.
When Heidenhain says an output is "TTL" and shows a square wave, it is always a differential signal, as required by Centroid.

Re: Heidenhain ROD 426 encoder compatibility
Thank you... i think I will have to create another question about wiring because wiring in heidenain documentation is not very clear to me. I will try to figure it out on my own but if I fail I will have to come backcnckeith wrote: ↑Wed Apr 14, 2021 2:51 pm fyi..for general Acorn encoder reference ..more info on the subject is here. viewtopic.php?f=63&t=921

Re: Heidenhain ROD 426 encoder compatibility
You need the encoder color code chart which tells you which color wire is which function so you can wire the DB9 connectorLenelyWolf wrote: ↑Wed Apr 14, 2021 2:59 pmThank you... i think I will have to create another question about wiring because wiring in heidenain documentation is not very clear to me.

Re: Heidenhain ROD 426 encoder compatibility
I’ve got it but like I said it is unclear to me.. acorn pin letters are different to heidenhain color code plus I’ve got 12 wires coming out of the encoder and only 9 pins on db9. obviously I’m not an electricianmartyscncgarage wrote: ↑Thu Apr 15, 2021 10:23 amYou need the encoder color code chart which tells you which color wire is which function so you can wire the DB9 connectorLenelyWolf wrote: ↑Wed Apr 14, 2021 2:59 pmThank you... i think I will have to create another question about wiring because wiring in heidenain documentation is not very clear to me.

Re: Heidenhain ROD 426 encoder compatibility
There is a picture of of the cable with all cable colors. Thanks for this info but still not unclear. Should I connect together brown/green and blue together for +5v white/green and white together to gnd? If so what about those two extra violet and yellow wire?martyscncgarage wrote: ↑Thu Apr 15, 2021 11:07 amUp-5vc
