DAS System User Manual
System Setup Menus. These menus will always appear on the Menu Selection
overlay (Cluster Setup can only be entered after you have defined a cluster using the
System Config menu). The System Configuration, Cluster Setup, and System
Monitor menus are described in more detail in the Reference section of this manual.
The following System Setup menus are available:
H
The System Configuration menu. This menu lists the modules installed in the
instrument. At initial power-on, the default groupings of modules are displayed;
you can select different module formations (groups of modules of the same
type). A typical example of when you might want to change a module
formation is when your application requires more channels in a module than are
currently defined. For example, by selecting different groupings of 92C96 cards
in a module, you can add needed acquisition channels.
The System Configuration menu also displays the current collection of modules
in a cluster; you can change the clusters with the Cluster Definition overlay.
H
The System Monitor menu. This menu displays the status of the modules
installed in the system as well as the clusters. It lets you see at a glance
which modules and clusters are running, which are waiting for their trigger
condition, which have acquired data and stopped, and which are autorunning.
If you acquire data for the selected module or cluster using Autorun, the
number of times that module or cluster has been started is shown in the
upper-right corner of the status line.
The System Monitor menu is especially valuable when you have defined
several different clusters and have them running simultaneously.
H
The Cluster Setup menu. This menu is only selectable after you create a
cluster using the Sys Configuration menu. It lets you define how modules
assigned to the same cluster interact. Specifically, it allows you to define
signals passed between modules, time-correlate data acquired by two
different modules, and specify Autorun conditions where a module acquires
data, compares it to a reference memory file, and based upon the compari-
son, stops or automatically repeats the acquisition.
Module Setup Menus. Module Setup menus that appear below the System Setup
menus correspond specifically to the module currently selected. For example, if
92C96-1 is the active module, the Config, Channel, Clock, Trigger, and Monitor
menus pertain only to this one module; other Setup menus will appear when you
select a different module (for example, 92S16-1 or 92S32-1). Refer to your
module user manual for complete details on all the menus, overlays, and fields of
the Module Setup menus.
Figure 2–5 shows the Setup menus for each module.
