Just installed a new SensarPro in my RV. Initially, I used it as a replacement for the existing wallplate, but the signal strength wasn't improved. I tried running the wallplate output to the SensarPro input and that gave me a better signal without overloading the SensarPro's amplifier. In cases where it might, I can always reduce the gain. My question is in regard to the USB connector on the SensarPro circuit board. I assume that it is used to program the unit at the factory. What other current uses might it have now or in the future?
