These brackets came with a JMI system I purchased on AstroMart but I manufactured my own brackets and don't need these. I don't know if they're original JMI brackets, and if they are, I don't know what scope they came off of. The Alt bracket has the short adapter cable to fit the 5 pin encoder jack and has a mounted RJ11 socket on the other end. When I recieved these there was a S1 encoder (small one) on the Alt bracket and a S2 encoder (big one) on the Az bracket. I'll throw in the eyepiece bracket that came off a SkyWatcher 10" Dob.
