Usage of the PL7 ID Device Redesign
The PL7 ID Device Redesign will be used in several classes of BMW.
General description of the RF transceiver PL7 ID Device Redesign
The RF remote control consists of a RF transceiver. The PL7 ID Device Redesign is
used to transmit the information for locking or unlocking the vehicle by a bi-directional
RF transmission for normal remote operation by pressing a button and via a LF Wake
Up.
In general the following functions are provided:
- Lock the car
- Unlock the car
- Unlock the trunk of the car
- Activate Panic Function
- Activate Special Function (at 4-button version)
- Engine Start of the car (via LF Wake Up)
For emergency start, when the battery power is too low, the PL7 ID Device Redesign
has a bi-directional LF-Transponder interface.
Power supply
The PL7 ID Device Redesign is provided with 1 Lithium battery (CR2450) that gives a
power supply of nominal +3V.
Buttons
There are three to four buttons which enable to lock and unlock the doors, to unlock the
trunk and activate a special function (e.g. panic-function of the car) when applied.
During activation, the button is forced to the ground via a “pull-up” within the microcon-
troller.
Protocol Overview
After a button-push the PL7 ID Device Redesign transmits a RF-code-telegram. When
the car acknowledges the success of the transmission the PL7 ID Device Redesign
starts the comfort-telegram, which is repeated until the button is released or the timeout
is reached. When the car doesn’t acknowledge the success of the transmission then the
RF-telegram is repeated on the second channel (Devices with only one channel repeat
on the same channel/frequency). This procedure is repeated 4 times when the button is
still pressed.

Typical usage pattern
The typical usage are 10 lock/unlock operations in 24 hours with a typical transmission
duration of 0.2 seconds.
⇒ 0.42 lock/unlock operations within one hour
Transmitter ON 0.084 seconds/hour
Transmitter OFF 3599.916 seconds/hour
Duty Cycle: TON / T(ON+OFF) x 100% = 0.084 / 3600 x 100% = 0.002%
