    Linear glass scale pin 9

    Just completed building and testing electronics for the Yuri Touch Dro system.
    Originally thought about using rotary encoders with 600 ppm operated by wire but when thinking more about it, resolution is too low.
    Looked at glass scales with ttl output and wondering what is the pin 9 I see in many instances.
    Can see 0v, 5v, shield connection, A and B outputs but the pin 9 has me stumped as to what it is used for.

    My guess would be Reference = Z = Index

    What he said. Reference (index) signal.

    OK...thanks for that.

    Another query....
    Linear scale supplier quotes output as "TTL square /wave EIA-442" so I imagine if I only need the TTL signal, just use A and B out?

    Re: Linear glass scale pin 9

    When I installed this system for my windows' glass I had a bad experience. So I haven't seen any difference installing this and even I have obtained a deep scratch on one of the window's glass. I don't know how it happened but it looked very bad. Thankful one of my friends told me that when he was abroad he saw a company that's business was glass graffiti repair laguna beach. So I thought that we also have such services and googled. I found their services and they came and repaired my glass. It was very qualitative and quick.
