PT2225 OUTPUT PINS
PARALLEL DATA OUTPUT PINS: D0~D5
Output Pins D0~D5 parallel data output pins. When PT2225 receives valid transmission, D0~D5 will send Parallel Latch Data Output. This data sustained until another data inputted entered.
SERIAL DATA OUTPUT PIN:
serial data output pin. When PT2225 receives valid transmission, will send Serial Momentary Data Output. This data sustained until next data code inputted. This means that when there data input, there output. serial data format follows standard RS-232 (9600 Baud Rate). signal does contain parity check bit, instead includes start bit, data bits stop bits.

Remote Control Receiver POWER SIGNAL ON/OFF:
PT2225
PT2225 receives signals with data codes from PT2221/2 Pin. This data code (D0~D7) 0100,1000. When PT2225 continuously receives this signal, then ON/OFF waveform repetitively generated. ON/OFF waveform consists 20ms high pulse generated after 200ms pulse. When PT2225 stops receiving signal, ON/OFF goes HIGH. Refer diagram below:
