Note that the logic on the inputs to the RP/RM/RX processors is reversed.
Therefore, when polling the lines to determine if a button has been pressed, a logic
high or '1' means that no button is pressed and a logic low or '0' indicates a
button press.
Contact TDT for assistance with custom button or LED configurations.
