    Yes the program will be on the DRO display unit, I was trying to get an understanding for how the callipers work, I have not played with or programmed an Arduino but it is sufficiently close to some of the languages I have worked with to see what is going on.

    I wonder if something is missing ie did the leads plug in directly to the dro? I can not get the --------- display off of the dro display

    Yer the instructions say that is connection to the calliper is lost or in this case not established.
    Obviously my idea that the DRO was powering the callipers was wrong.
    Would be nice to get a scope on the DRO see if it is pulsing the clock and on the callipers try to read the out put.

    I probably missed the bit of the thread where you said where the DRO set up came from and why it did not have the correct cables for the callipers.

    So should the dro pulse the calipers too then.

    I do not have a scope unfortunately. Let me see what they have on eBay.

    The dro came with the mill. But the cables were already plugless

    No sorry I miss read what was going on in the programme the clock is also an input to the arduino (or DRO) from the calliper.

    If you are around on Saturday I can bring my laptop and PC scope over, we know the baud rate so should be able to see the data.

    thanks mate
    that makes sense then that will be why I see +1.5V on 3 of the 4 wires from the calipers.
    I am about Saturday morning off to essex about lunch time

    thats cool, I will have another play with it tomorrow, you never know I may crack it, it just peed me off today so I left it be. Seen some nice scopes on ebay that hook up to a lap top some have 8 channels!

    I have an old two channel Tenma PC scope, usual story, acquired for a job and hardly used since, still interesting to poke around with things occasionally.

    I needed one ages ago to test a crank shaft sensor ending up replacing sensor and it was a broken wire in the loom!

    Picked up one a while back. Keep meaning to drag it in and hook it up to my audio interface to view my waveforms.

    Spaghetti is ready.

    Well not quite but the dro is all wired up and working now to get soldering and heat shrinking and get rid of the wages.

    A big thanks to all that inputted on this. And a even bigger thanks to zx9 for the leads and rj9 connectors. I saved you a trip with the scope. I would have liked to of seen it. I should invest in one. 20191003_155219.jpg 20191003_155200.jpg

    Great news, though I was looking forward to a bit of problem solving.
    You just need to document what worked, hopefully it will help out anyone else trying to do the same.

    Here is my wiring diagram the wires were different in each end of those cables. I also removed the batteries from the calipers too. I just need to figure out why the dc power supply ain't working or maybe it was my 2 power supplies I will try a 3rd.

    I also need to mount the cables where they won't get dammaged. I may even use some conduit or spiral binding that I have. 20191003_173233.jpg 20191003_172529.jpg 20191003_173222.jpg 20191003_162408.jpg
