ASCII vs. SREAL

I was able to get my data acquisition vi to work properly, but only when the storage mode was set to ASCII. When set to Single precision REAL, read buffer returned what seemed like junk data. It isn't really clear why.

Update
I'm getting close. There are some subtle bugs in the Keithley 6430 Buffer Read.vi having to do with SREAL acquisition. If you look at the raw data coming back from the machine, the header is actually three bytes, not two. There is also a line feed (LF, #010) at the end.
