Typical Applications
• Remote Keyless Entry
• Remote Monitoring
• Remote Controls
• Wireless Security Systems
Product Description
The DK1000R 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. Everything 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 as an
FCC15.231 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 transmitter, DK1000T.

DK1000R Theory of Operation and Application Information
The 9V battery is installed in the back of the receiver
by sliding open the battery door located below the
moveable stand. The battery is clipped into the con-
nector provided, placed in the compartment, and the
battery 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 battery life.
The receiver uses the HCS512 decoder from Micro-
chip. 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 manufac-
turer.
The 315 MHz receiver uses a 4.748 MHz crystal which
may be identified by the label on the top of the crystal
can. The following pages show the schematic for the
315 MHz receiver, the bill of material for the 315 MHz
receiver, the printed circuit board layout for the 315
MHz receiver. These materials, along with the Gerber
files for the PCBs may be found on the Internet at
www.rfmd.com.
OPERATION
The receiver is operated by first turning on the power
as described previously. The LEDs may be observed 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 indi-
cating 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
portion of the stand (marked "1" on the case) and pull-
ing out the bottom portion 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 normal
operation while receiving a signal. The three LEDs
marked "S1", "S2", and "S3" are illuminated as corre-
sponding buttons are depressed on the transmitter.
The buzzer is activated by pressing the fourth button
on the transmitter. The remaining LED, marked
"VLOW" is illuminated to indicate a low battery condi-
tion. This indicates the need to replace the battery. An
antenna is printed onto the PCB for convenience.
