I=92m looking to interface to an Omron E6C-MPZ1X2 absolute rotary encoder w= hich I have very little info on. I've worked out how to hook it up electric= ally, now I'd like to decode the gray code serial output. It appears to be = a fast (500K) asynchronous data stream. I have no information on the data f= ormat. Has anyone done this before? A data sheet on the encoder would be ni= ce. It seems to be normally sold with a decoder unit and I can get data on = that. (http://www.omron.com.ru/dynamic/managers/manage_14/files/E6C-M.pdf) Any help appreciated.
