    hi sry i couldn't find the schematic diagram online. im doing a combination of the two receivers together. which means convert the two outputs of circuit by using a xor gate, then the output of the logic gate goes to the serial port connection. i had tried various connection, but the circuit didnt not work. i already take note on the voltage of the IC chip itself and the circuit, something is wrong inside. does anyone can help me?? thx thx alot
