Regarding your string parsing... Maybe I don't understand your protocol, but it looks to me like it's just a simple query/response protocol. So I'm not sure what you mean when you talk about a continuous stream of data.
It seems like you'd just send "?Temperature1\n" and immediately do a VISA Read knowing that the data you expect back is for "Temperature1". I'd suggest that you terminate your data with an end of line character, and use VISA's termination character functionality to simplify the read. E.g., have the satellite return something like "!Temperature1[Data]\n". Then configure "\n" as your VISA termination character. You could leave out the "Temperature1", since you should know what you queried for. But, it does make a good sanity check if you identify the data that comes back with the appropriate channel name. Is the data encoded in ASCII? If so, then the "Scan from String" and "Spreadsheet String to Array" functions will be useful. If it's in binary format, you'll probably end up using the Type Cast function. I'd suggest downloading some of the native LabVIEW instrument drivers on http://ni.com/idnet/. E.g., download something for an oscilloscope that includes a serial interface. This should provide you with several examples of how to read data with VISA and parse it. This should also show you many examples of how to get real-valued data (orange) instead of pink or blue. I hope this helps. Brian
