I am putting a DRO on my 2nd milling machine and ran into a bit of an issue.
The scales are not able to be read by my new DRO. The new DRO does read the scales on my other milling machine, so I believe there is no issue with it. My old DRO will not read the new scales either. I have tried various options in the setup screens but nothing seems to work.
Perhaps it's as simple as changing the pinout of the connector, but I am not sure. I purchased them back in February, and have contacted the seller, but no response yet.
Looking at the data from the ebay listings, I think the problem is the DRO is EIA-422 and the scales are RS232. Would it be as simple as just switching some wires in the connectors on the scales?
Thanks
The DRO is this one
It shows the comm parameters for the DRO
And these are the scales. The only describe the interface as Linear Scale Interface: DB9(RS232)
