General description of the RF transmitter PL2 ID
The RF remote control system consists of a RF transmitter and a RF receiver
mounted within the control unit. The RF transmitter is mechanically integrated
in the head of the key. This transmitter is used to transmit an information for
locking or unlocking the vehicle by an unidirectional RF transmission line for
normal remote operation by pressing a button.
In general the following functions are provided:
- Lock the car
- Unlock the car
- Unlock the trunk of the car
Power supply
The transmitter is provided with 1 Lithium battery (CR 2032) that gives a
power supply of +3V.
Buttons
There are three buttons which enable to lock and unlock the doors and to
unlock the trunk.
During activation, the button is forced to the ground via a “pull-up” within the
microcontroller.
Typical usage pattern (for Europe only)
10 lock/unlock operations in 24 hours with typical transmission duration of 2 seconds
→ 0,42 lock/unlock operations with one hour
Transmitter ON 0.84 seconds / hour
Transmitter OFF 3599.16 seconds / hour
Duty Cycle: TON / T (ON+OFF) x 100% = 0.84 / 3,600 x 100 % = 0.02%
