COM and DAQ - comparison
Posted on 2003-11-14
Can I use a "simple" COM port to receive data from external devices, for example, to get information about the temperature in a vessel and respectively to send signal by which to make one or other action or I need to use so called Data Acquisition Board (DAQ board)? What are the possibilities and limitations of "simple" serial ports? What are the advantages of the DAQ boards? Thank you very much!
