The program to use is MakeHex
[Link: john.fine.home.comcast.net]

From the decode you get a protocol name. That should match the name of one of the .irp files in MakeHex.zip (otherwise give more info here and you'll get more specific help).

From the decode you get a device or device.subdevice number. Edit the .irp file and change the device line to your device number (save the edited file).

In file explorer Drag/Drop the icon of the (edited) .irp file onto the icon of makehex.exe
That creates a .hex file.

Open the .hex file and in it find each function based on the numbers you got from the manufacturer.
