Viewing the Segment Tree

The Segment Tree is a visual representation of the locations and associations of

the Portal Gateways, associated Controllers and I/O devices in your segment. As

you conﬁgure your Portal Gateways, sign on Controllers and conﬁgure additional

hardware in your system, you can drag them to the folders and subfolders you

create in the Segment Tree.

Figure 53 shows an example Portal Gateway in the Segment Tree.

To view the Segment Tree

1 In the Segment tab, select the segment you wish to work with.

2 Click on the Portals tab. The Segment Tree pane displays on the left, and a list

of all prepared devices displays on the right. The ﬁrst item in the Segment Tree

is the folder for the selected segment, in this case, Acme University.

The Segment Tree is also viewable from within the Readers tab. See “Adding Con-

trollers to the Segment Tree” on page 89.

Organizing your Segment Tree

You can organize your Segment Tree by Portals and Controllers, or by building

locations, or by any other method you prefer. Remember, the Segment Tree is pro-

vided as a visual aid and does not affect the actual hardware or communication to

the devices.

The ﬁrst level below the Segment level in the tree might contain, for example,

folders for Portals and Controllers, or folders for building locations. You can create

sub-items in each folder as needed, for example: First Floor, Second Floor, ofﬁces,

laboratories, and so on. There is no speciﬁc protocol for creating the hierarchy;

only that it makes sense to your operation so that when you add other elements to
