    Chinese linear scale Need Pin out

    Hello Everyone

    I got my self a Jing JC800 TTL linear scale, trying to hook it up to my DRO Tech Model DRO-3M

    The Pin out is wrong and i been looking for days for the pin out or what wire is what and i cant find anything
    And the ones i do find the colors don't match what i have

    The Scale has a LM339N IC https://www.ti.com/lit/ds/symlink/lm...google.ca%252F

    I only have 4 wires, White, Yellow, Red, Black and the shield
    I test the wires on the IC and i get
    Black = Pin 1 Out 1
    Yellow = Pin 2 Out 2
    Red = Pin 3 Vcc
    White = Pin 12 Gnd

    Maybe this scale might not work on my DRO,
    Can i connect it to a ethernet smoothstepper or a UC300ETH ???

    Thanks
    Biggs
