I have some of those SSR's. Some are leaky when off. Others when they go bad, stay on 100%.If you have a critical process that needs to turn off, beware.

Link to display on ebay. drivers and manual at bottom. I could not get the driver to work with win7x64.

A usb header works on the display.

Thanks

What about the display board?

Is there also a pinout for the beta board?

Thanks. How about the display?

Did you try clearing cache? Maybe the history and cache are full or being used for whatever reason.

Does anyone have the link to the w/c 32 manual?

Is this on your Delorean? :P

Thats what I want to do with the staged zeners.

I could. The challenge is to autodetect it and compensate.

I'm getting closer to actually doing something with this. So with the zener idea in mind, my thinking is to use a 10v for the 1st unmonitored drop out. Then to auto select the battery voltage ie 24 or 36 I will monitor the 2nd and 3rd zener and determine if I need to use analog 2 or analog 3 for...

If my resistors are 4k7 and 14k1 and I use the 4k7 to measure the drop across. At 38v the drop will be 8.1v and at 32v the drop will be 6.9v. To say that the14k1 would always be fixed would also be wrong. So the question is how to deal with this. Create a table or calculation that acounts for...

As the battery voltage drops the drop across the resistor will drop as well but in a proportion. 38-32 volts would yield an approx 1 volt error unless my thinking is wrong.
