another sensor IC is used, carefully check its pin-out on the data sheet before inserting it. Solder at 3 places.

Assembly Options:
Option 1. If only logic outputs are desired, the board is now complete. Do not perform Option 2 or 3.
Option 2. If relay outputs are desired, complete the following:
Insert D1 and D2. The dark band shows orientation Solder at 4 places.

Insert J2. See the instruction for J1, above for the correct orientation. Solder at 6 places.
Insert RL1 and RL2. Note that the relays can only be inserted in one orientation. Solder at 16 places.

Insert J3. See the instruction for J1, above for the correct orientation. Solder at 6 places. (see photo above)
If relay outputs are desired, the assembly is now complete. Do not perform Option 3.
Option 3. If transistor outputs are desired, complete the following:
Short J4, J5, and J6 with solder bridges or wire jumpers.
Insert J3. See the instruction for J3 in the section above. Solder at 6 places.
If pull-up resistors are needed, they can be located in the positions marked for D1 and D2. D1 and D2 are not used
in this configuration.
This completes the assembly with Option 3.
Operation:
Programming:
Before use the receiver must be programmed for use with the IR remote of your choice. You must select any two buttons on
that remote. The receiver is capable of learning codes from about 99% of existing IR remotes: almost any remote can be
used.
Replacement or universal IR remotes are available at low prices so a separate, dedicated remote can be purchased. However,
many remotes can control several different devices: for instance, a TV remote may also be able to control a VCR or a DVD
or an audio device. On such remotes, you can choose an unused device (such as an audio player or VCR) and then any two
buttons for that device. Many devices do not use all the buttons on the remote so there would be no conflict if unused buttons
were selected. Some buttons may have no assigned code: if so, the LED will not blink while programming. If this occurs,
just select another button.
Programming steps:
1. After choosing the desired remote and buttons, apply power to the assembled IR receiver.
2. To place it in the Programming mode, the “a” or “1” or left most DIP switch is turned ON and then immediately
turned OFF again. The Yellow or Channel 1 LED should blink and then stay lit.
3. Aim the remote at the receiver IC on the circuit board and press the first selected button. The Yellow LED should
blink and then stay lit.
4. Press this same button three more times for a total of four times: the yellow LED should blink each time.
5. After the last time, the Yellow LED should blink several times and then stay lit.
6. Repeat the above sequence (steps 3, 4, and 5) for the second button.
7. After the fourth repetition of the second button the Yellow LED should blink several times again and then turn off.
This signifies that programming is complete for those two buttons.
You can reprogram it for different buttons or a different remote at any time by repeating the above procedure. DIP switch
“a” is left in the off state for normal operation and during programming. It is only turned on briefly to initiate programming
mode.

External Connections:
J1, J2, and J3 are Molex header connectors with standard 0.025” square pins and a 0.1” pin-to-pin spacing. This style is
extremely common and a large number of mating, female connectors with different termination styles are available. These
styles include solder, crimp, and insulation displacement termination. The mating connectors are not included in this kit.
The following illustration shows all the external connection options.
Relay vs. Transistor Output Configuration:
For operation with relay outputs, the three jumpers; J4, J5, and J6 must all be open (not shorted). D1, D2, RL1, and RL2 are
installed. Outputs are taken from J2 and J3 as shown in the tables above.
For operation with transistor outputs, the three jumpers; J4, J5, and J6 must all be shorted. This can be done with a wire
jumper or by touching their small gaps with a drop of solder on the tip of the iron to create a solder bridge. D1, D2, RL1, and
RL2 are not installed. Outputs are taken from J3 as shown in the table above. With no pull-up resistors on the board the
transistor outputs will be “open collector” style where the load circuit provides the pull-up Voltage. If pull-up resistors are
needed, they can be installed in the locations marked for D1 and D2: ¼ Watt resistors will fit in these locations. For most
applications that require a pull-up resistor, values between 1K and 10K Ohms would be chosen. Actual values for these
resistors would be calculated from the current requirements of the circuit that is connected to these outputs. As the supply
Voltage for the receiver circuit is 5V, pull up resistors lower in value than 100 Ohms would exceed the power rating of a
1/4W resistor and should be avoided ( 5*5/100 = 0.25 W). In general the higher the value, the better as long as enough
source current is available for the driven circuit. As a wide range of values may be needed, these resistors are not provided in
this kit.
Output Actions:

The outputs can be configured for several types of action. This configuration is made with sections “c” and “d” of the DIP
switch, SW1. The available choices are as follows:
SW1-c SW1-d Operation
Off Off Momentary
On Off Toggle
On On Definite
Off On this state is not defined and should not be used
Momentary action will activate the outputs while the code is being received (while the remote button is being pressed) and
deactivate them when the code is no longer being received.
Toggle action will alternate states of the outputs each time the code is received.
Definite action involves Channel 1 only. Channel 2 is not used and remains in the off or deactivated state. The channel 1
output is activated when the first (Ch 1) code is transmitted. It remains activated when that transmission ceases and
additional transmissions of that, Ch 1 code will not change the output state. The channel 1 output is deactivated when the
second (Ch 2) code is transmitted. It then remains deactivated when that code transmission ceases and additional
transmissions of the second (Ch 2) code will not change the output state. Thus, one code only activates the output and the
other code only deactivates it.
