  • Page 34: Enhanced Monitor Fan Control

    Enhanced Monitor Fan Control With the front panel fan switch in the VAR position, the Enhanced monitor controls the fan speed based on slot temperature limits you specify. With the fan switch in the FULL position, the fan operates at full speed. Essentially, the Enhanced Monitor’s fan control has two contrasting functions: 1) keep the VXI modules installed in the cardcage cool and 2) operate as quietly as possible.
  • Page 35: Setting Enhanced Monitor Limits

    Consequently, this warning is generally too late for most applications. For example, the +5V supply in the HP E8404 is capable of providing up to 90A (peak current, refer to Appendix A). It is therefore capable of delivering the regulated voltage into nearly a dead short -- 0.06 .
  • Page 36: Handling Warnings

    SYSTem:NVSave memory. Enhanced Monitor Measurement Cycles The HP E8402 and E8404 Enhanced Monitor monitors over 80 signals throughout the mainframe every two seconds. These measurements are fed to the display, the Status Subsystem (for warnings), the History Subsystem (for storage), and the Fan Controller. The display shows the measurements pertinent to the screen displayed, updated every two seconds.
  • Page 37: Using The History Queue

    Using the History Queue The HP E840x Enhanced Monitor provides many history feature records such as: minimum and maximum values, histograms, operating times, and event logs. As you begin to use the mainframe, the history features won’t be of much use -- very little has happened, there is no history to record. But as time passes, the history features can provide valuable insights into the trends of your test system.

    Terminal or HyperTeminal. These applets provide a convenient method of using the Enhanced Monitor. Use an appropriate nine-pin female to nine-pin female RS-232 cable (such as the HP 24542U) for connection between the PC and the Enhanced Monitor. Configure the Terminal settings for generic TTY, and the communication settings to match those of the Enhanced Monitor.

    The program examples are written in ANSI C language with HP VISA extensions. To run one of these programs you must have the HP SICL Library, the HP VISA library, an HP-IB interface module installed in an external PC, an HP E1406 Command Module, and the enhanced monitor in either the HP E8402A or E8404A VXI mainframe.
