T. Herzog / PDSCA1 Seite 2 von 4 29.08.13 Huf Hülsbeck & Fürst 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.
