Thanks Everyone for the input! I'm now able to read values from my sensor. I now have 2 additional questions.

1. Is there a better way to send serial; data than the way I'm doing it? Anyone have a routine that they think works better?

2. It seems like my returned values vary quite a bit. I don't have access to a scope, but it seems that the sensor is returning pretty constant voltage. it returns 0 - 10 v I am using a voltage divider made up of 2 2.2 K resistors to shift the sensor output to 0 - 5 volts. Any hints on making the system more stable? Slow down the conversion time? My requirements are pretty easy, i need to read the sensor no more than twice a second.

Thanks again for everyone's help!
