- Clear the IR code learning window (click the small button next to "refresh locations") and place your cursor into the code learning window. Either type or paste the http string directly into this window. The string MUST begin with http and be no more than 200 characters in length. Click on "Pick location" and select a memory location between 21 and 40. IMPORTANT - the location chosen here corresponds to the stored IR code that will trigger this string. If you want this http string to be triggered by the code in location 1 then store this string in location 21 - use location 22 for IR code 2 and so on. Click on "Name", enter a name for the http string and then click on Upload, wait a few seconds and the http string name will appear in the chosen memory location.
