Repair of Unit & Circuit Explanation
4.1 Repair of Unit
Exchange an old unit.
4.2 Circuit Explanation
If User presses specific Switch of transmitter, MCU makes inherent serial value
and Encryption value, so it print what CPU make data, at the same time , RF IC get to be
ENABLE.
Printing data are falsified into TxIC and it synthesize through CRYSTAL. Compounded
frequency is amplified by TxIC and it transmits through antenna from matching circuit
diagram of output.
FOB receives RANDOM DATA through LF Antenna and print to encrypt result value from
MCU, at the same time RF IC get to be ENABLE. As following, it transmits PATTERN
Antenna how to change falsification, synthesis, and multiplier.
