KH2 TRANSMITTER EVALUATION BOARD
THEORY OF OPERATION
TRANSMITTER EVALUATION BOARD
The transmitter board is powered by an on-board 3V CR2032 lithium battery. It
5

has eight SPST pushbutton switches, the state of which are encoded into a data
stream by the module. If a switch is closed, the module will capture the settings
of the 10-position DIP switch address bits and pushbutton states for encoding
and transmission. The transmitter will transmit continuously when any switch is

closed or when Transmit Enable (TE) is pulled high. This board has a prototyping
area with all of the transmitter lines brought out to a header for easy access by
external circuitry.
RECEIVER EVALUATION BOARD

The receiver board is powered by two AAA batteries. The KH2 Series receiver
exhibits a sensitivity of greater than -112dBm, so under optimum line-of-sight
conditions, the transmitter / receiver link can operate over distances of up to

3,000 feet. The data recovered by the KH2 Series receiver is internally decoded.

KH2 RECEIVER EVALUATION BOARD
If the settings of the 10-position DIP switch on the receiver board match the
address setting of the transmitter board, the data lines are updated to match the
state of the data lines (or pushbuttons) on the transmitter board. To demonstrate
this, one data line is used to drive a LED while another is used to activate a
buzzer. Switching transistors are used as drive buffers because the KH2 receiver
cannot directly source the current necessary to operate these devices. This
board has a prototyping area with all of the receiver lines brought out to a header
for easy access by external circuitry.
USING THE KIT
Using the kit is straightforward. Simply attach the antennas, turn on the power,
and press one or both of the buttons on the transmitter board. When S0 is
pressed, the buzzer will sound; when S1 is pressed, the LED will turn on.

DEVELOPMENT USING THE PROTOTYPING AREA
In addition to their evaluation functions, the boards may also be used for actual
4
product development. They feature a prototyping area to facilitate the addition of

application-specific circuitry. This area has a connection to V CC at the top and
ground at the bottom that can be used to power the added circuitry.
NOTE: The CR2032-style battery on the transmitter board has very low current capacity,
with only about 3mA available for external circuitry. If added circuitry requires a higher
current, the battery must be removed and the board powered from an external source.
The holes are plated and set at 0.100” on center with a 0.040” diameter, making
it easy to add most industry-standard SIP and DIP packages to the board.
On the transmitter board, the data lines and the TE line from the encoder have

been wired out to a header on the right side of the prototyping area. On the
receiver board, the data lines from the decoder plus the PDN, and DATA lines
from the receiver have been wired out. This allows for easy access to connect
external circuitry to the modules, the encoder, and the decoder. Data line D0 is
connected to the buzzer and D1 is connected to the LED.
