Weeder Digital Input Board vs. XTension

[George Handley]

Jerry,

I didn't know some of these things. The last he told me was that he was helping his Mom,,, I think in Chicago go through her last stages of what ever ailed her..

I do have a serious XTension problem I've been fighting for 9 months. I can not get a Weeder WTDIN-M Digital Input Board to work. https://weedtech.com/wtdin-m.html <https://weedtech.com/wtdin-m.html>  And, because of that I can't, I can't finish a variety of other projects. 

James has been helping me. Terry Weeder has been helping me. I've had a couple of local qualified PC Gurus try to help, but nobody can get these boards to talk to XTension. I use a lot of Terry's boards, but when I try to run his Digital Input or Digital Output Boards... they are a different animal.

James immediately identified my problem with at least the Digital Output Board. In order for many different Weeder Boards to work, you have to wire the board in such a way that is the opposite to common sense and convention. Basically, this Digital Output Board requires the circuit board be controlled with what I call "negative switching."  Just as it sounds a negative switched point simply means the actual switching mechanism is placed of the ground side of a circuit instead +12vdc side.

Well, after learning all that from James I got the Output board up and running in no time, but the Weeder Digital Input doesn't work that way, nor does it work in a conventional way. It just plain doesn't work no matter what I try. 

For example, my meter's not pulling the voltage it should to turn things on and off. The specs state that 
Digital Inputs need the following to happen to turn on. High (Or On) = +4V to +40V Transient protected and

Low (Or off) = -40V to +0.8V High = +4V to +40V  all transient protected. This is a 12 vdc card I'm woking with and I'm getting 0 vdc in the off state as I should but only .5 vdc in the On state.

I'm in the hopes that there's somebody on this list that knows what my problem is.

Stay safe, Jerry and best wishes,

George
