I've got the EC2 output data format from Tracy and even wrote a program 
to display that data a while ago. Biggest problem is the voltage levels 
are not +/-12V rs-232 signals but 0/5 volt so you need to build a little 
circuit to fix that before you can plug that into a pc or pda. Here's 
some info at <http://casson.2y.net/Glastar/EC2_Tuning.html> And of 
course that data stream will not have any of the temp or pressure data 
that most people are interested in.
