The Edit dialog appears with the device listed (Figure 22).

The Edit dialog for a device component only shows some of the device component’s properties. Typically, these are key properties required for communications, and will vary among drivers (to access all properties of the device component, go to its property sheet).When a single device is selected in the Edit dialog, you can edit any property except Type (it was fixed when you added the device). Included is the ability to edit the Name of the device in the station. This is equivalent to the right-click Rename command on the component.

The following related topics also apply:

The Edit button in the Device Manager allows you to edit one or more device components in the station in a single dialog. Before clicking Edit, use standard Windows keyboard controls to highlight (select) multiple devices (e.g. hold down Ctrl key and click desired devices).

Edit is also available on the Device Manager toolbar and the Manager menu.

The “gang” edit feature is useful for making the same change in multiple (selected) devices. For example, as shown in Figure 23, you can change “Poll Frequency” in multiple devices at the same time (versus editing this individually).

When you have the Edit dialog open with multiple devices, you can also click on select ones to make individual edits (e.g. Name, or any other editable property), during the same dialog session where you made “gang” property edits. When you click OK, all the changes are applied to the device components as made during your Edit session. For more details, see “About gang edits.”

When you have multiple devices selected in the Edit dialog, properties that must be unique (such as Name) are automatically unavailable (dimmed). However, note that some properties that typically should be unique (often address properties) may still be available for “gang edit,” as this rule is not automatically enforced. Typically, when editing these properties, you should verify only a single device component (row) is highlighted in the table.
