In this case, you need the IFIX software and the EDA toolkit installed on your PC. You should then modify the local software to write all readings from you HV system to a local FIX database. This database can then be monitored by the local IFIX software and all alarms sent on to the other nodes monitoring alarms.
One example of a HV system is the PISA boxes which provide HV to the Central and Muon Phototubes. These boxes were used in run I and are interfaced to a CAMAC module and controlled through the CAMAC crate. In this case, there is a software driver for Windows NT provided and supported by the Computing Division. This driver assumes a SCSI to Jorway 511 or CC 73A interface. Having a saoftware driver enables local software to be written for the controlling PC that accesses the PISA Box channels and writes the readings to a local FIX database. Such drivers are difficult to write and can require up to six months for an experienced programmer to create.
The important issue here is that a software driver exist for Windows NT that interfaces to the particular hardware that you plan to use. It is advisable that you try to make use of one of the existing systems as a way to do this as in that case most problems have already been solved for you and you can piggyback on the efforts of others. One example of a system that is doing this is the Luminosity detector that is using the same CAEN HV system for powering its phototubes as the Plug HV is using.
If your equipment needs to be interfaced to the CDF M&C system, please contact J. C. Yun or John Yoh, and look at some of the other tutorial web pages in this area.
