Thanks Chuck.
Unfortunately I do not have the time to find parts to build custom circuits. I have no electronic support on the team. I will have to leave this for the off season and use one of the Banner sensors from past years.
This looks similar to the FP issue of last year, the vendor did not investigate what the requirements are for plug and play.
