SpecMan4EPR is built using Client-Server Architecture. The Server computer handles the hardware, while the Client computer provides GUI for experiment visualization and execution. Client is automatically created on the same computer when Server executable is launched. One can create any amount of additional Clients on different computers and connect them over TCPIP.

SpecMan4EPR has only one Experiment ready for execution or executed at a time. This Experiment is located on the Server. After finishing of the experiment Run, all data are transferred to Clients. Every Client connected to the Server will have then an exact copy of the Experiment. If the Queue is used all data are saved on Server and are never transferred to the Client.
