Hello dhuff, Thank you for contacting National Instruments.
I haven't been able to find any VIs built that take LabVIEW data and convert it to nCode, but it can be done. You would need to know details of the way the data is stored in .dac files including endian order, whether it's channel oriented or block oriented, etc. Use the data manipulation VIs in the advanced palette if you need to mainpulate bits, bytes, or words. Then you can use the LabVIEW File I/O VIs for the actual file writing. Post back if you have any issues using these VIs. Regards, Gerardo Garcia National Instruments Applications Engineer
