Page 4: Introduction
ICI2 INTRODUCTION Welcome to the ICI2 kit (and if you don’t have the time, wired and tested). We will give you an overview of IR remote controls and how they typically work and also how this kit works to help you understand what you’re building. -
Page 5: Theory Of Operation
ICI2 THEORY OF OPERATION The ICI2 may look quite simple, but there is actually quite a lot to it inside the parts. Many items are inside the IR receiver part (U4) that if built up with dis- crete components would never fit in this little kit case! Inside this part there is an IR detector diode, amplifier, AGC circuit, bandpass filter, a peak-hold cir- cuit, an integrator, comparators, and an output amp. - Page 6 There is a speed jumper you can install to allow the ICI2 to work with these remotes. If an incorrect speed remote control is detected, the microcontroller emits a special beep to let you know the format is wrong.

The part is then soldered securely to the board (2-4), and the remaining lead length is then clipped off (5). Notice how the solder joint looks on close up, clean and smooth with no holes or sharp points (6). ICI2 Page 7... -

Page 10: Assembly Steps
ICI2 PC BOARD ASSEMBLY STEPS Assembly of the ICI2 is pretty simple, but it requires some time and some patience. We will start with the side that has the power jack, and we will move from there using the power jack as a reference. - Page 11 27. Install J8, 2 pin header, above R9. 28. Install U2, 68HC908JK1 microcontroller, to the left of S2. Line up that notch again. This is the “brain” of the ICI2. This is what learns the different buttons from your remote.

47. Install Infrared module U3. Don’t worry about U4, It’s for another type of module that we used to pack with this kit. It did the same thing, but was a different shape. ICI2 Page 12... -
Page 13: Setup And Testing
SETUP AND TESTING To begin testing the ICI2 we will need the following items: AC Power supply between 9 and 15VAC or.. DC power supply between 9 and 15VDC. A remote control It’s finally time to apply power to your kit. Please be sure before you do that the bench is clear of any scrap component leads and take one final look at your solder connections before you proceed. -
Page 14: Programming
PROGRAMMING YOUR ICI2 Now that we have made it through the initial ‘turn on’ steps, it is time to program the microcontroller for your individual codes. Remember to install some fresh batteries in your remote control and aim the infrared LED towards the photo sensor. - Page 15 RESETVOL USING THE ICI2 To test out your ICI2 you need a line level audio source like a CD player, VCR, or stereo. Find something with audio out that has standard RCA jacks. Plug the audio out right and left into J1 and J5. You now need to connect J2 and J9 to an “audio in”...
