I have a Bridgeport 2 axis DRO display #1810122 Serial #823 presumably for a J head or a 2J or maybe a different bridgeport alltogether. It has the 2 round XJ1 and YJ2 6 pin connectiors. I don't know much about the other features and controls on this unit. It has the X Select, INC move, ABS position, and Y Select lamps, with the adjacent corresponding gray buttons as well as a CLR, RCL, A->I and SUM button.
I got this off ebay, and the fellow who sold it to me said it needed a missing part replaced.
I'd like some more information on this, perhaps any BP documentation, and which BP scales I can use it with.
