The packets of serial output that are generated by the transmitter encoder and sent to the receiver decoder by wireless, infra red or other means are fed into serial input pin 40 of the decoder. A packet is stored and the address bytes within it are compared with those of the decoder address pin settings. Address and data bytes within a packet are also compared with each other and if at least two of them match then the data is passed to the output pins. Each of the output pins can both source and sink 25 milliamperes.
The data outputs are not momentarily interrupted if the transmitted data pattern is changed while transmitting, as happens with some decoders. This is important when machinery is being controlled and continuous control of some functions must be maintained.
