Hi, I'm working on an external case for my MO LCD. I've uploaded some pics to the gallery. Henry, in the last pic, what is the positive and what the negative terminal of each CPO of this particular LCD?

- +
- +
- +

or

+ -
+ -
+ -

?????

Best regards / Fernando D.

Hello...

Are you talking about the LK402-12 that SilmarilS did...?

It's an LK204-25-V that was a special for Bit-Tech.net

Ok, now that we have the LCD identified,

what is the polarity of the GPOs? I need to know it before I start wiring all the stuff that I want to place inside the box.

Thanks a lot / Fernando

Just like it says in section 2.2 of the handy dandy manual, it's

- +
- +
- +
- +
- +
- +

And they are ACTIVE LOW for what it's worth.

OOPS,

Believe it or not, I did look at the manual but did not see the - + over the GPOs drawing. Oh well, ....

Thanks a lot / Fernando
