Testing the RRW1B

To test the RRW1B receiver, you will need to use a functional RRW1A trans- mitter. You just need to have faith that you have assembled everything cor- rectly up to this point! It can be very difficult to troubleshoot this item without some good equipment so we will have to do it the old fashion way if it comes to it. See the troubleshooting section for more details if you need to.

For now you will need:

An IR remote and equipment this goes to (Cable box or some- thing).

Two “wall wart” power supplies, one for each the transmitter and receiver.

A working RRW1A transmitter.

Begin by setting up the transmitter and receiver where you would like to use them. The receiver is usually set on top of the components you wish to control with the IR LED positioned so that it will beamed downward into the face of the components where their IR sensors are located. The transmitter can be set up wherever you are planning on using the remote control. For now, keep it in the same room so you can see the Data LED on the front panels of both units. Keep in mind that you do not want your remote control directly activating the target equipment without being repeated through the RRW1 system first!

Turn on the power to both the receiver and transmitter. The Data LED on the transmitter (RRW1A) should be on by default while the Data LED on the re- ceiver (RRW1B) should be off. If the Data LED on the receiver is flashing or continually on (without sending data through the transmitter of course), R20 (on the receiver) will need to be re-adjusted. Use a small screwdriver to adjust R20 on the RRW1B if needed so that the LED just turns off. It may slightly flash a little due to noise in the receiver being seen on the data line. Adjust R20 until the LED just goes out and stays out; leave it at this setting. The best possible adjustment is where the LED is out, but it is really close to the point where it turns on again. You have successfully adjusted the squelch setting!

With the receiver properly tuned, aim the remote at the transmitter and press a button. The Data LED should flicker on the transmitter from the remote’s data. The Data LED on the receiver should begin blinking at the same time. This means your wireless link is working!

Now just test some functions on the remote to see if it controls your device and your off to the races! Try moving the transmitter to another room now and see if everything still works. You should get a fairly decent range that should more than enough to cover most people’s homes.
