433 MHZ REMOTE KEYLESS ENTRY RECEIVER
Product Description
The DK1001R is the receiver half of our remote keyless entry system evaluation kit. It is designed to allow the user to easily and quickly demonstrate the operation of the RF2919 in a typical application. Ever ything needed to demonstrate a one way receiver is included. The RF2919 is setup to demonstrate a typical keyless entry system using a rolling code decoder while operating at 433 MHz. A batter y is included and the antenna is printed on the circuit board. This unit is designed to work with the mating transmitter, DK1001T.

DK1001R Theory of Operation and Application Information
The 9V batter y is installed in the back of the receiver by sliding open the batter y door located below the moveable stand. The battery is clipped into the connector provided, placed in the compar tment, and the batter y door replaced. The receiver is activated by moving the small lever switch to the "ON" position. The power switch may be accessed through an opening in the clear cover on the front of the receiver with a small tool. When the receiver is turned on the LED marked "POWER" will be illuminated. Turning the receiver off when not in use will extend batter y life. OPERATION The receiver is operated by first turning on the power as described previously. The LEDs may be obser ved to be illuminated corresponding to the button that is being depressed on the transmitter. The LED on the receiver will be illuminated indicating that the power is on. The "LEARN" LED will flash while the receiver is decoding a transmitted signal. The buzzer will be activated indicating that the corresponding button is being depressed on the transmitter. The stand on the back of the receiver may be extended by lifting up on the upper por tion of the stand (marked "1" on the case) and pulling out the bottom por tion of the stand. The receiver may then be placed for easy viewing while operating the transmitter. The receiver has one lever switch for turning the power on and off and one pushbutton used in learning the transmitter. There are five LEDs on the receiver PCB. One of the LEDs indicates that the receiver is activated (power on). Another LED is used during the process of learning the transmitter and flashes during nor mal operation while receiving a signal. The three LEDs marked "S1", "S2", and "S3" are illuminated as corresponding buttons are depressed on the transmitter. The buzzer is activated by pressing the four th button on the transmitter. The remaining LED, marked "VLOW" is illuminated to indicate a low batter y condition. This indicates the need to replace the batter y. An antenna is printed onto the PCB for convenience. The receiver uses the HCS512 decoder from Microchip. Four pads are included for programming this device. It is preprogrammed to operate in the desired manner for this application. Additional information about this device may be obtained from the manufacturer. The 433 MHz receiver uses a 6.6128 MHz crystal which may be identified by the label on the top of the cr ystal can. The following pages show the schematic for the 433 MHz receiver, the bill of material for the 433 MHz receiver, the printed circuit board layout for the 433 MHz receiver. These materials, along with the Gerber files for the PCBs may be found on the Internet at www.rfmd.com.
