How to Integrate Scientific
Instruments to Computers
In today’s research world, scientists use a lot of instruments to
“see”, to “touch”, to “feel”, and to “listen to” the unknown
objects, so that they can discover the hidden natural principles.
Our planes are filled with many instruments all collecting data
that needs to be integrated.
Serial interface is: a data channel that
transfers digital data in a serial fashion
USB (Universal Serial Bus): hardware interface
for attaching devices to a computer
Ethernet: The global standard for physically connecting
computers and devices together in a network.
Therefore, integrating instruments to PCs
requires Ethernet, USB, Serial, or a wireless
link, driver, and software to make the data flow!
