Glass scale /DRO compatibility

Well, yes - Nick Farr gave a link up-thread. But then I'd have to buy one from them @ £20ish! Against £2 for a nine pin plug from eBay.

Part of my reason for doing this now is that ARC have glass scales on clearance, so I can save a few quid. I ordered one on Wednesday, sent out today (Friday) - I wasn't expecting such promptness in the current circumstances, so my thanks to ARC for that.

I'm pretty sure now that the ARC scales and the Sino DRO are compatible and it's just a matter of matching up the pins.

If it doesn't work with the pin connections/ wire colours Dave (SoD) suggested I shall have to experiment. I haven't got a 'scope but I found this in my electrics box:

It's an RS232 diagnostic thing - if I remember right the LEDs flash Green/Red according to TTL False/True voltages. Might it be pressed into service here ?

Just to let you know how it went. I did ask M-DRO if they had a suitable adaptor cable, but they were unable to advise with only the model numbers of the encoder and the readout to go on. They wanted pinouts for each end. So I made up my own adaptor based on the info Dave (SillyOldDuffer) gave above.

It seems to work! So I just need figure out how to physically attach the scales to the mill (WM14 - so not a lot space to play with, but I think it's doable) and I'll be in business.

My thanks to all for info/discussion, Robin
