We use these type of adapters for HVAC controls. This one looked identical to the much more expensive BB brand converters, inside and out, but this did not work. Also tried the one from UXCELL, but that was DOA as well. Unless there is something else wrong with our setup, these are poorly manufactured. I gave it 2 stars just for the benefit of the doubt that these just aren't compatible. But they should be.

For the price, it might be worth the risk to get a good one, but I think you get what you pay for...

***UPDATE***

Don't waste your money on this cheap one, get one that actually works like the one linked below. Or at least it worked well for me.
