4. CIRCUIT EXPLAINATION
1. After IGNITION, When EMS Data transmitted to the receiver, the received Data is
analyzed.
2. After data analyzing, When EMS need to order Write key or Challenge service, U1
send data to U10
3. U10 what are transmitted data by U1 modulate FSK way, and then it transmit
transponder via Antenna.
4. Transponder what receive data from U10 reply information what U10 is ordered
after processing data
5. Data received from the transponder to reply with U1 and U10 after the
