Schematic Configuration

In the Schematic Configuration tab, NI Switch Executive renders a schematic, or a graphical representation, of each switch in a virtual device. Click the device schematic to quickly configure a virtual device, including channel aliases and hardwires.

Note  NI Switch Executive represents third-party, IVI-compliant switch modules and independent topologies in the Schematic Configuration tab as channel listboxes.

The Routes and Route Groups and Devices listboxes and the Schematic window compose the Schematic Configuration tab. In the following figure, a matrix topology schematic displays in the Schematic window:

Routes and Route Groups

The Routes and Route Groups listbox contains all the route groups associated with a virtual device.

Note  If the virtual device does not have any existing route groups defined, NI Switch Executive creates a default route group, RouteGroup0, in the Routes and Route Groups listbox to which you can add a route.

Use the buttons at the top of the Routes and Route Groups listbox to manage route groups and routes.

Button	Function
	Adds a route group to the virtual device and the Routes and Route Groups listbox. When routes are added to the route group, the new route group displays in the Schematic window.
	Adds a route to the virtual device and the Routes and Route Groups listbox. This button is disabled when the Show Routes checkbox is disabled.
	Creates a copy of the route group and adds it to the virtual device and the Routes and Route Groups listbox. The copy of the route group displays in the Schematic window. When the Show Routes checkbox is enabled, this button can copy routes in addition to route groups.
	Deletes the route group from the virtual device and the Routes and Route Groups listbox. The route group no longer displays in the Schematic window. When deleting a nested route group, this button disassociates the child route group from the parent route group. When the Show Routes checkbox is enabled, this button can delete routes in addition to route groups.

Tip  You can also right-click any name in the Routes and Route Groups listbox to manually manage the routes/route groups.

Show Routes

Enable the Show Routes checkbox, located below the Routes and Route Groups listbox, to manage the individual routes of a route group. When you enable the Show Routes checkbox, the create route button is enabled, and you can use the copy button to copy a route.

Filter

Use the filter textbox, located directly below the Routes and Route Groups listbox, for searching. Type the first characters of a route or route group name, and all names that match the search string display in the Routes and Route Groups listbox. The search string is not case sensitive.

Devices

The Devices listbox contains all the IVI switches associated with a virtual device. Click a switch device to display the channels, routes, route groups, and hardwires associated with the switch in the Schematic window.

A checkmark displays to the left of the device name in the Devices listbox to indicate that a route exists on the device.

Schematic

The Schematic window is a graphical representation of all the channels, routes, and hardwires of a route group on a particular NI switch device associated with a virtual device.

When you associate a channel with a hardwire, the hardwire number appends as a superscript to the channel name in the schematic.

A route displays in color on the schematic to represent its electrical connectivity. If an electrical path is shared between two or more routes, the routes display in the same color on the schematic.

Note  A route in the schematic that appears dimmed denotes that the route is not configurable in the Schematic Configuration tab.
