My DS18B20 should be at my door on Monday. So next week I start more playing. The EZIO8SA I ordered arrived yesterday.

Since the connection diagram shows +5; Signal and Ground.
You are not using the pasasite method of powering the DS18B20. Correct?

So those that maybe reading this. The DS18B20 can do both direct and parasite power. The DS18B20P only does parasite power and is what I have seen on a few web sites for sale.
Parasite Power is where the DS18B20 steals power from the signal buss and most times the interface has been designed to do that type of drive.
