Greetings fellow geeks,

I have searched this forum and read all the docs I can find. I'm still confused about how to hook up a led to this rev 1.4 LCD.
I have managed to get the Dallas temp sensor to work and hooked up 2 different fans to the hi powered GPO's. My LCD doesn't look like the one in the PDF file.

Mine has a row of 4 white colored 3 pin connectors (WOL). This is where I have my Dallas sensor plugged in.

Next to it is a row of 3 brownish red colored 3 pin fan type connectors. This is where I have hooked up my fans.

There is a group of pins that might be the internal USB hookup.

There is a group of pins that have "trx" and something I cant remember. I think these are serial connections?

I have to assume all this is correct since everything works as expected. Sooooo..........

Where are the 5 volt low powered connectors that are under software control?

I have a server PC case with 3 extra leds, one for fan failure, two for temperature warning.

Hardware = LK202-24-USB Rev1.4 or is it a MX214

Thanks BRB

If you look on page 8 on the manual, your low power GPOs that you can control through software is to the right of your high power connector. The link to the manual is connected below.

The group of pins labeled TxRx is an option for controlling the display with another controller.

If you have anymore questions or concerns, please feel free to ask.

Tom,

Don't know why I didn't see that PDF link before.
I'm on it now
