DK1000T
· Remote Keyless Entry · Wireless Security Systems · Remote Controls · Remote Monitoring
The DK1000T is the transmitter half of our remote keyless entr y system evaluation kit. It is designed to allow the user to easily and quickly demonstrate the operation of the RF2516 in a typical application. Everything needed to demonstrate a one way transmitter is included. The RF2516 is setup to demonstrate a typical keyless entry system using a rolling code encoder while operating as an FCC 15.231 type device at 315MHz. A battery is included and the antenna is printed on the circuit board. This unit is designed to work with the mating receiver, DK1000R.

Introduction The small 3V lithium button cell is installed in the back of the transmitter board by sliding the battery completely into the clip provided. The larger flat surface of the battery, marked with a "+" should be in contact with the clip, also marked with a "+" and should be facing away from the printed circuit board. It will normally require some force to insert the battery completely. When the batteries are first installed and the devices are activated, the receiver may not recognize the transmitter. This is normal and only indicates that the receiver must learn the transmitter. This is accomplished with the following procedure: 1. Install the batteries, if not already installed 2. Tur n on the receiver using the power switch as described above 3. Momentarily depress the button marked "LEARN" on the receiver. This may be accessed through an opening in the clear cover on the front of the receiver with a small tool. This will cause the LED located next to the button to be illuminated. 4. While the LED is illuminated, depress any button on the transmitter. When a button on the transmitter is depressed, the LED on the transmitter will be illuminated. Continue depressing the button on the transmitter until the LED on the receiver is no longer illuminated. Release the button on the transmitter. 5. Depress a button on the transmitter once again. Continue depressing the button until the LED on the receiver begins to flash. Release the button on the transmitter. 6. The LED on the receiver will stop flashing. The process is complete. 7. To verify proper operation, depress any button on the transmitter. An LED on the receiver should be illuminated and the LED located next to the "LEARN" button should flash. When one of the buttons on the transmitter is depressed, the buzzer will sound. The transmitter has four pushbuttons that activate the transmitter. The four buttons represent four separate functions that could be activated using the system. This evaluation board uses the Microchip encoder chip for secure transmissions. Further information about this device may be obtained from Microchip Technology Inc., Chandler, Arizona, USA. An LED is included to indicate that the device is activated and four pads are included for programming the HCS300 device. The device is preprogrammed with a dummy serial number. An antenna is printed onto the circuit board for convenience. The transmitter is simply operated by pressing any of the buttons. While the button is depressed, the LED on the transmitter is illuminated. The 315 MHz transmitter uses a 9.83 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 315 MHz transmitter, the bill of material for the 315 MHz transmitter, the printed circuit board layout for the 315 MHz transmitter. These materials, along with the Gerber files for the PCBs may be found on the Inter net at www.rfmd.com. The 315 MHz transmitter has been tested by L.S. Compliance, Inc. for compliance with limits contained in various provisions of Title 47 CFR, FCC Part 15, including: 15.109, 15.205, 15.209, 15.231b, and 15.231c. The device was found to be compliant. Included in the following pages are some excerpts from the test report. The complete report is available on the Inter net at www.rfmd.com.
