also you are pulsing voltage into the RC where as connecting the pins is a ground to signal connection... that could be why

What I assume is happening is that the output pins on the PIC on the IR board, is set to 0 which would ground the signal on the RC and give a 0. When it sees the IR pulse it changes the output pin to 1 which is a high 5V. That would give you a 1 in programming.
