The measurement system KSP is old and presently not developed. It is controlled by the interface EEC-19 mounted inside the computer to the ISA slot. New computers haven't this kind of connector. Controlling this KSP system by new computers is possible through the USB port, but is necessary to install an additional interface between USB and the measurement device.

The measurement system KSP 2 is controlled by the printer port LPT of the computer.
