Enable Developer mode. Daniel of remotecentral has created a wonderful little program to do this for you. You can download it here:

[Link: remotecentral.com]

Once you have downloaded and installed it, enable developer mode.

Open ProntoEdit and a button you want to program, hit SET IR, then the Advanced button to reveal the RC5/6 code generator.

Leave the radio buttons on RC5.

There are two windows in the RC5 generator, one for system address, always use 10.

For the command code, convert the binary to base ten and enter.

Finished code entry in ProntoEdit should look like this:

[C]RC5 10 1
