Hi Len,

I knew Sony had this many bits since I have played with it for years. But it will vary like the wind from one IR transmitter & mfg to the next.

If you're not sure just set it to read in 50-60 (or more) pulse times, then look for the BIG pulse between data packets. There's normally a large break time between packets so you'll know where it starts, what's in between, and the end timing.

Then you will find a few that only transmit a few bits and stop. Those are really a bear to figure out. It's not as nice as a good logic analyzer, but it works with the majority of IR transmitters.
