Check for good supply voltage: The RS232 RTS output should be between 7v and 12v. If not, disconnect the circuit and measure again to see if the circuit is drawing too much power. Check that the regulator output is 5v. If voltage at RTS pin is pulling down to low, measure the current draw somehow. The circuit should not draw more than 5ma of current. The output of the IR receiver should normally be high(5v), and should pulse low when it picks up a signal.
