is straight and flush to the board. Then solder the rest before moving on.

‰31. Install C10, the large 1000 uF electrolytic capacitor. Double check the orientation before soldering as this is especially critical with this component. Follow the same guidelines you used to install C9!

‰32. Install ANT1, the 6” piece of buss wire. Solder the wire in place where the circuit board has been marked “ANT1” for easy identification. Use a ruler and trim off any extra wire if longer then 6” (5 3/4” to 6” works great).

FINISHED!! 32 steps may not seem like a lot but we are done with the transmitter! You should go back through the steps before moving on and check for proper orientation of devices before plugging in the power however. This will prevent damaging anything by accident. Check capacitors for orientation, the IC, and also the rectifier diode as preventative measures.

TESTING THE RRW1A

Method #1

To begin testing the RRW1A you will need the following items:

AC Power supply between 6 and 12VAC or..

DC power supply between 8 and 14VDC.

A known functional IR remote control

Apply power to J1 and turn on the power switch (S1). The Data LED (D1) should turn on and stay on, acting as a dual purpose power LED. The only time D1 will turn off (or become very dim) is when an active 38 kHz data stream is being received by the IR detector module (U1).

A quick functional test is to verify that the Data LED flashes off when you point an IR remote at the IR sensor (U1). The flashing indicates that the data from the remote control is being seen.

If you wish to go one step further and you have a radio which can tune to

433.42MHz (AM mode), you can verify that the oscillator is working. Tune the radio for 433.42 MHz and turn on the RRW1A power switch (S1). Press a but- ton on the remote control and you should be able to hear the data stream be- ing transmitted from the RRW1A. The selectivity of your monitoring radio may be much tighter than that of the receiver (RRW1B) so you may need to tune up or down a bit on the dial to find the signal. Adjusting the frequency of the transmitter for exactly 433.42 MHz will not be needed due to the front end characteristics of the mating RRW1B series receivers. This makes life easy!
