Siemens VDO Automotive AG SV C ERFile: S:\Postzula\Dwmc\Func_TX_Dwmc.doc Page 2 of 4General description of the RF transmitterThe RF remote control system consists of a RF transmitter and a RF receivermounted within the control unit. The RF transmitter is mechanically integratedin the head of the key. This transmitter is used to transmit an information forlocking or unlocking the vehicle by an unidirectional RF transmission line fornormal remote operation by pressing a button.In general the following functions are provided:- Lock the car- Unlock the car- Unlock trunkPower supplyThe transmitter is provided with 1 Lithium battery (CR 1616) that gives atension of feeding of +3V.The battery inversion is protected mechanically.ButtonsThere are two buttons which enable to lock, unlock the doors and unlock thetrunk. During activation, the button is forced to the ground via a “pull-up”within the microcontroller.LEDThe LED is turned on between transmission blocks.VariantsSiemens type designation frequency difference5WY 8201 315 MHz without transponder5WY 8202 315 MHz with transponder-master5WY 8203 315 MHz with transponder-non master5WY 8204 433 MHz without transponder5WY 8205 433 MHz without transponder5WY 8206 433 MHz with transponder-non masterAll variants have the same schematic, pcb and layout.
