The microscope is actually directly controlled by a "server" computer running Windows 2000. The software the user interacts with (SM_GUI, sm_script for stack control) can run on any other computer (we call it the "client" computer) and talk to the server through the network. At the beamline, of course we provide client computers to use, but in principle you can run the microscope from your own laptop.
Each microscope uses a protocol and a data connection, each of which is assigned a TCP/IP port number (see Table 11.1).
