COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-6560
FCC ID: NQE1005
CRC Bytes
2 bytes of CRC data transmitted to ensure accuracy of
transmitted data
CRC = x^-15 + x^-13 + x^-1
Explanation 16 Bit CRC Generation:
If lsb of data byte == 1, EXOR 0xA001 into CRC
Shift data byte right
Shift CRC right on every bit (0 rotates into msb)
Shift the data byte 8 times (8 bits)
Shift the 8 bytes of data in the message through the
crc.
Baud Rate
Data is transmitted using Manchester encoding (BITOUT = DATA
&& CLOCK) at 16129 data rate.
Deviation
150KHz – selectable using potentiometer on PCB.
