Troubleshooting Guide

PROBLEM: The green Data LED does not light.

SOLUTION: 1) The LED (D1) may be installed backwards. Re-check its orien- tation as described in the assembly steps. 2) Check pin 3 of U1 for +5V. If you have no power here, check the wall transformer to make sure the center lug is positive and the ring is negative for a DC supply. The polarity is not a factor if you are using an AC transformer.

PROBLEM: The green LED doesn’t flicker off when I aim my remote at it.

SOLUTION: You are trying to relay an IR remote that is modulated at some other frequency than 38 kHz. There is a variety of ranges available, but 38 kHz is by far the most common. Most consumer components operate at 38 kHz. This system ONLY works 38 kHz carrier signal remotes.

PROBLEM: I’m using a radio tuned to 433.42 MHz and I can’t hear the remote control’s signal being re-broadcasted.

SOLUTION: Check to make sure your radio is set to receive AM signals and that your receiver isn’t so narrow you are missing the signal. Tune around a bit and you will probably find it. If not, it’s possible you made a mistake during as- sembly of the sections surrounding Q1 and Q2. Please check your work and make sure components are mounted flush to the board.

PROBLEM: I just can’t make the darn thing work!
