This keypad is based on the T2. The K2 Programming suite comes with a IR Library manager that is WAY ahead of the old Library manager that comes with the T2 software. The K2 IR Managers has a nice big HEX tab...... that you can highligh, Copy and paste directly into ProntoEdit.
Will load up your T2 CML Library just dandy.
