ICI1 INTRODUCTION Welcome to the ICI1 kit (and if you don’t have the time, the wired and tested version). We will make an attempt at helping you understand IR remote controls and how they typically work, and also how this kit works to help you understand what you are building.
ICI1 THEORY OF OPERATION At first look the ICI1 may seem quite simple, but there is actually quite a bit to it on the “inside” of the components. Many items are inside the IR receiver part (U4) and if built up with discrete components it would never fit in this little kit case.

When you train the ICI1, the micro controller looks at the IR data stream and rejects those codes it sees as useless or unverified. The ICI1 looks at the data...
(1). 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). ICI1 Page 7...
If a problem does occur, the manual will lead you through step by step in the troubleshooting guide until you find the problem and are able to correct it. ICI1 Page 8...

ICI1 REMOTE CONTROLLER INTERFACE ASSEMBLY Assembly of the ICI1 is fairly easy, as we use all through hole components, 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.

NOT mount the LED flush to the board, but mount it as high as possible, or about 1 1/4” off of the board. The LED will eventually be bent over to peek out of the front of a case. ICI1 Page 13...

18. Install the socket for U1, the Motorola 68HRC908 20 pin micro controller IC. It doesn’t matter which way you install the socket but it definitely matters which way you place the IC in the socket. Don’t be afraid ICI1 Page 14...

To take advantage of this, we will use common components and place them in all four output stages at once, this will save a lot of back and forth with ICI1 Page 15...

Your Remote Control Interface kit is now complete! Have a final look over your work, paying particular attention to the orientation of diodes, capacitors, and IC’s. Remember that any problems you find now can save time and effort after the unit has been cased up and final assembled. ICI1 Page 16...
TESTING AND PROGRAMMING YOUR ICI1 To begin testing the ICI1 we will need the following items: AC Power supply between 9 and 15VAC or.. DC power supply between 9 and 15VDC. A remote control Its finally time to apply power to your kit. Please be sure before you do that you clear the bench of any scrap component leads and have one final look at your solder connections before you proceed.
LED should illuminate. The LED should be lit, initially; this will change after we program the microcontroller IC. PROGRAMMING YOUR ICI1 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.

USING THE ICI1 Well, there really isn’t much of a secret to using the ICI1, but we thought some wiring ideas would help. Primarily you will want to wire to the ICI1’s four outputs to control some separate functions. The relay contacts effectively isolate the ICI1 from the circuit or appliance you wish to control, so that both AC and DC appliances may be controlled.
- Note that this application will work for any DC appliance (as long as the cur- rent ratings of the relay are not exceeded). Use care in applying the correct polarity to the DC device when wiring. Typical Low Power AC Wiring: -120 VAC light being switched on Hot side. (Black-Hot) (White-Neutral) ICI1 Page 21...

“stone wall” of a problem only to have a fellow technician see our obvious error. It is sometimes very difficult to see your own mistake; taking a break can often solve this common problem. ICI1 Page 23...

It is usually something simple. Have your board revision handy to help our technicians find the proper schematic for your needs. You can email our tech support as well at the ramseykits.com website. Oh, please count to ten before calling, taking some deep breaths first... ICI1 Page 24...
ICI1 INFRARED CONTROLLER INTERFACE SPECIFICATIONS Here are few of the commonly requested specifications for the ICI1: J1, 2, 3, and 4 Relay Outputs - Contact Rating: 5 A, 120 VAC / 28 VDC (Resistive) - Rated Contact Current: 5 A - Max.
'missing' 10 K parts ("Hum-m-m, I guess the 'red' band really does look orange!") Ramsey Electronics project kits are packed with pride in the USA. If you believe we packed an incorrect part or omitted a part clearly indicated in your assembly manual as supplied with the basic kit by Ramsey, please write or call us with information on the part you need and proof of kit purchase.
