XBee 5V/3.3V Adapter Board (32401, Rev A, 03/11/2010)

gobblegook

I am using your "XBee 5V/3.3V Adapter Board" (32401, Rev A, 03/11/2010) and am not sure how to read or use the CTS signal.

In your docs, it looks like "/CTS" becomes "CTS" without any circuitry.

So my question is: Circuitwise, how do I use your Rev. A adapter board CTS signal with a 5V processor?

Is CTS true high or low?

Do I need a pull-up or another buffer chip to use the signal?

Thanks,
Jay

Most 5v devices will take 3.3 as high.
