4. 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(U1) makes inherent serial value
and encryption value, so it is transmitted to the FSK&ASK pin of TX_IC, at the same time,
TX_IC gets to be ENABLE.
- Printing data are falsified into Tx_IC and it synthesize through crystal(X1). synthesized
frequency is multiplied and amplified by Tx_IC, it transmits through pattern antenna
from output matching circuit.
- FOB receives random data through LF Antenna and prints to encrypt result value from
MCU, at the same time TX_IC get to be ENABLE. As following, it transmits pattern
antenna how to change falsification, synthesis, and multiplier.
