I was developing an application using an applications software package ( not written in Forth ) called LABTECH NOTEBOOK and a plug-in card from "Data Translation, Inc." ( located in MA ), but these proved to be awfully slow in execution. That is, it could give me a very low sampling rate. Although RTD's plug-in card is much cheaper, it involves additional programming labor as compared to LABTECH NOTEBOOK. ( I want to do a PID loop ). Besides, I wonder if RTD will be faster ! If yes, then how much faster ? Any suggestions, info or education will be much appreciated. rajuk@umree.ee.umr.edu
