I've got an old XLO 602 knee mill with an old Heidenhain DRO mounted on it. The DRO itself is acting up and with the low cost and features of a new import DRO, I went ahead and ordered one. My hope was to adapt the old 8/9 pin Heidenhain Stecker plug to a DB9 plug. I've been doing some digging and was able to find this image from elsewhere on the forum:
My DRO was listed as a PNP device, and has a pinout of:
The scale lights up from the 5v connection, so I've got at least that going in my direction.
The one scale I'm working on presently is marked LS 503 962460 E6 D-8225.
My question is this: Can these old scales be adapted to a new Chinese DRO? If not, I'll refit the machine with new import scales, but would love to refurbish the ones that are already mounted if it's not too much hassle.
