    Default Dro Scales DB9 to H15 Fagor Innova 20i-T

    Hi all,
    I have a Fagor Innova 20i-T Dro with Meister scales that I purchased several years ago for my lathe.
    I have never felt that confidant in the accuracy and it has got pretty bad recently and I have noticed there are times when the scale is moving and the display does not change other than the numbers go blurry while the scale is moving. I have disassembled the scales and cleaned everything with alcohol, but it still has problems.
    I recently purchased a cheap Dro kit from ebay so I could use the scales, but find that my Fagor takes a H15 D plug with 15 pins instead of the common DB9 pin plug.
    I have the Fagor head set to 0.005mm but the X axis does not change the third digit, (5 Thousandths of a mm) when the scales move, but the Y axis does. I have changed the resolution for the X scale to 0.01 and it seems to be much more accurate now.
    My questions are, 1. does anyone know the pinouts for the DB9 plugs for typical TTL scales and the H15 pinouts for the Fagor dro?
    2. does anyone know of an adapter that can interface a 9 pin scale male plug with a 15 pin Dro socket?
    3. Has anyone had any experience with scales becoming unreliable and not reading while moving?
    4. What would cause a scale to work OK at 0.01 resolution and not 0.005mm Resolution? (the scales are supposed to be 0.005)

    I hope I have given enough detail for a reply, if not feel fre to ask for more info.

    Hi Baz, sorry to hear about your issues with what is a pretty high end DRO with commensurate price tag. I think this is what you need to adapt: https://www.machine-dro.co.uk/m-dro-...onnectors.html. I have used machine-dro before for Newall units and they are good to deal with.

    Regards - Ralph

    Sounds like the readout unit itself with the numbers fading etc. Can you reset the unit back to factory settings in the menu?

    I've had 2x Miester dros and scales for well over 10 years, never cleaned them and the have never missed a beat.

    I have the pinouts for a lot of them, I will go through my paperwork latter today and get them out. You can find them online as well.
    I have changed a few of scale plugs over the years from round to DB9

    I just googled dro DB15 pinouts and dro DB9 pinouts there is a fair bit of info on there for you.
    If you bought a new readout with the set, I'd be changing at least the one miester scale that you think is playing up over to DB9 and try it on the new readout.

    thanks for that

    I am in communication with Machine-Dro atm and they have been extremely helpful and that adaptor should facilitate the DB9 to H15 once I can verify that the pinouts are compatible.

    Thanks for the reply,
    I also googled the DB9 to H15 pinouts and did not come up with anything helpful. I have tried Fagor to DB9 etc and still not come up with anything conclusive.

    I have swapped the Meister scales from x to y and the problem followed the scale not the DRO input, so I am thinking it is the scale. I even tried swapping the scales with the readers and the DB9 reader worked perfectly with the Meister glass scale, but from memory still did not read the 0.005 digit. The Meister reader performed very poorly with the newer glass scale and was worse than the Meister one, which leads me to think that reader is more likely at fault than the glass scale having some defect.

    The new readout works ok, but I would rather use the Innova readout if I can, but may end up going with something that works eben if it is lesser quality.

    I really appreciate everyone's help on this.

    I have tried a factory reset as well as changing settings in the menus with no improvement. Fagor Innova dros have what they call "easy setup" that is supposed to read the scales and set it's own settings for the scale. This has never worked as per the manual from new.

    I have searched for the pinouts and tried to compare what I have found with the physical wiring on my connectors and am still a little puzzled as they do not seem to totally resemble what I have.

    I am assuming that scales with DB9 connectors are generally the same pinouts so the scales I have just purchased would run on most dros that have a DB9 socket

    I am pretty sure that the Meister scale in question may have been faulty from the start and I did not realize till recently when the problems became more exaggerated. I know there have been so many times I have done the final trim and found I am undersize even though the display says otherwise, and I never understood why. I have had no trouble with the y axis and it still registers the 0.005 digit fine.

    All the DB9 ones I have are the same pinouts, Sino, Miester and GSM. I did get the wiring order wrong one time changing from round to DB9 and it didn't do any damage to anything.
