HELP! Weeder Funnies updated

Sorry George,

I've got your emails in the queue here just not enough of me to go around the last couple of weeks as usual.

Looking at the spec of the WTDIN board, and how I’ve used the 2 of them here and in one other location, they have a pull up resister already on board connected to the 5v rail. That means that to make them change state you need to connect them to the ground terminal that is on the board. There are 2 Gnd labeled terminals in between the inputs and the outputs. I have those connected to one connector of all the contacts that I’m measuring and the other side of the contact goes to one of the inputs. So if you just take a piece of wire from the Gnd and short it to any of the inputs it should generate either an on or an off to XTension. I know that some of them needed to be setup as reverse logic in XTension, but that shouldn’t matter one way or the other. You should see a command for the endpoint change when any of them are connected to Gnd, or disconnected from Gnd.

I just received the new parts I need to redo the basement Weeder Digital Output board and new relay board, so I'm tabling that questionI for the moment, but I'm still in need of your opinions to resolve my garage Weeder Digital Input Board. Does that board require the negative switching used in the Digital Output Board or does i work like all the WTDIO boards that use the  positive side for switching.
