Having enjoyed the benefits of DRO vernier scales on my mill they are sometimes a little awkward to read. I thought the little connections on each DRO would allow me to plug in to a readout display but on enquiring with the supplier these displays are only for glass scale systems which he tells me are much more accurate. Further googling revealed that these are serial connections for hooking up to a computer - I have an old but still serviceable laptop which might serve as my read-out display. Can anyone put me wise on this subject in terms of hardware needed to hook up the DRO's to my pc and the software required ?
many thanks
