16-27 DK1001R rev a1 020109 16 ref. designs & design kits DK1001R 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. 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 onandoffandonepushbuttonusedinlearningthe 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. 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 433 mhz receiver uses a 6.6128 mhz crystal which may be identified by the label on the top of the crystal can. the following pages show the schematic for the 433mhz receiver, the bill of material for the 433 mhz receiver, the printed circuit board layout for the 433mhz receiver. these materials, along with the ger- ber files for the pcbs may be found on the internet at www.rfmd.com.
