Send command to decoder chip. This is a variation of command It will read a number of parameters and packet them as in following format and send it to decoder chip.

  • Page 16: Control Command For Decoder Chip

    3. Control command for decoder chip Important: This chapter describes low level command for scanner control function. If you already USI to do scanner programming, you don’t need to care about this chapter. In general, it is not suggested to use level command to control scanner, because there are timing issue on serial communication programming , and it is always need communication expert to do that and it is hard to explain it on document.
