Have you ever been so frustrated with the range of your remote
that you go to the extreme of rearranging your entertainment
room just to make it work? Tired of having to bounce your IR
remote off of ceilings and walls? Do you want to run your
system from another room? Here is the answer to your prayers!
Extend the range of your remote controls as far as you need;
it's only limited by the length of wire you use!
IR receiver module with sensitive element can receive your
remote control up to 36 feet away before re-broadcasting it.
The RR1 reconstitutes the receive signal using a PIC micro
controller, restores noisy or weak signals, and then re-broadcasts
the IR remote signals to your components via a long wire (tested
over 500 feet!) to a high-efficiency IR LED.
Extend the range of your remote control around corners or down
floors by running a wire to an IR LED in front of the components
you wish to control.
Works with almost any remote control (38 kHz carrier), does not
need to be programmed.
Will operate from 8V to 16V AC or DC. Use our AC125 wall adapter
for long operation.
LED indicator lets you know when you are receiving an IR signal
or not.

    RR1 works. This will better help you understand what you are about to build. As simple as it may look, the RR1 is one of the best remote repeaters money can buy thanks to some specialized technology we have added to restore normally unusable signals.
  • Page 5: Theory Of Operation

    RR1 THEORY OF OPERATION The RR1 may look simple but there is actually quite a lot being done inside each one of the parts. Many individual components are packed inside of the IR receiver part (U2) itself; so many in fact that if it was built up with discrete components, it would never fit in this little kit case.
  • Page 6 LED on and off at 38 kHz during the entire send sequence. The LED may be on only about 50% of the total time to send the data. To achieve the maximum transmission range and peak performance from the system, we’ve cranked up the current a bit to get More Power!!!! RR1 • 6...

    (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). RR1 • 7...

    RR1 REMOTE REPEATER KIT ASSEMBLY Assembly of the RR1 is straight forward but it does require some time and patience. To get our bearings, we will start with mounting the power jack and move on from there. It serves as a good reference point for the other parts.

  • Page 12 21. The IR LED wiring offers you a bit of flexibility to custom match the RR1 to your application. You will need to determine how long of a wire you will actually need to fit the job at hand and then cut it to length. The 8 foot piece of wire that is supplied with the kit is more than enough for most of the common component cases available today (we didn’t want to...

    Sometimes the walls near you will reflect enough IR for the equipment to detect so it would be hard to verify if the RR1 is working. Now turn on the RR1 and press some remote control buttons. You should see the...
  • Page 14: Using Your Rr1

    We thought this might be a good spot for some mounting ideas that may help with the usage of your RR1. Primarily you will want to put the RR1 in a discrete location that isn’t too obtrusive. It should be where you can easily point your remote control’s IR data in a fashion that is unimpeded by other ob-...

    38 kHz. There are a variety of ranges available, but 38 kHz is by far the most common. Most consumer components operate at 38 kHz. The RR1 ONLY works 38 kHz carrier signal remotes. PROBLEM: The LED lights, but the IR LED seems to have no effect.
