The D-ZERO experiment at the Fermilab Tevatron Collider deploys approximately 1000 independently controlled high voltage channels. The VME based front-end of the high voltage system is controlled by 68020 processors. The host processes running on VAX/VMS computers communicate to the front-end via gateway and token ring. The D0 Control Data Acquisition software package handles all the messages between the host and front-end. The front-end hardware/software is structured so as to ensure robustness and flexibility. The host software provides an intelligent and intuitive high level control and monitoring of all the D0 high voltage channels. The high level control of high voltage
helps optimize the response of D0 detector components.
