DATA CODE D7 can be controlled by this pin, allowing 128 kinds of data to be transmitted. D7 is set to “0” by connecting the pin to VDD , and to “1” by connecting the SEL pin to VSS. As the input of this pin is high-impedance, it must be connected to either VDD or Vss. The custom code can be set by the diode connected to the CCS pin and the KI/O pin. Outputs “L” while the REM pin is outputting a transmission code. Transmission Code The transmission code consists of a leader code, 16-bit custom code, and 8-bit data code+8-bit inverse code of the data code, they are also sent simultaneously, giving a total configuration of 32- bits per transmission. The code uses the PPM (pulse position Modulation) method, with “1” and “0” differentiated by the time between pulse. Each code consists of 8-bits, and simultaneous transmission of the inverse code allows configuration of a system with an extremely low error rate.

If KI/Oi are connected to CCS by diode, Cn ( n = 0~7 ) =1. If KI/Oi are not connected to CCS by diode, Cn ( n = 0~ 7 ) = 0.The custom code low-order 8 bit Cn’ ( n = 0 ~7) are determined by pull-up resistor to the KI/O pins. If pull-up resistors are attached to the KI/Oi pins, Cn’= Cn. If pull-up resistors are not attached to the KI/O PINS, Cn’= CnB.
