Rajant Corporation ME BreadCrumb User Guide
Detailed information for a BreadCrumb device can be viewed in the Info Area by selecting the
BreadCrumb device in the Topology Area. A BreadCrumb device can be selected by single-clicking it
with your mouse. The selected BreadCrumb device will be highlighted with a dashed border. A
description of the detailed information is provided later in this chapter.

3.1.2.1. BREADCRUMB DEVICE NAME
The BreadCrumb device’s name is displayed in the upper-left area of the BreadCrumb Box. The name is
assigned by an administrator using the process described in the Section called
Configuring Individual
BreadCrumbs . This allows the administrator to distinguish between multiple
BreadCrumb devices in a BCWN.
If the BreadCrumb device has no name assigned, its ID is used. The ID is a unique, alphanumeric, non-
editable string used internally by the BreadCrumb device.
3.1.2.2. TIME SINCE LAST UPDATE
Each BreadCrumb device sends periodic information updates to BCAdmin, in intervals ranging from
about 5 seconds to about 20 seconds. This number shows how long it has been, in seconds, since
BCAdmin last heard from this BreadCrumb device.
By default, BCAdmin will color the BreadCrumb Box red and make a sound if a BreadCrumb device
has not sent an update for 60 seconds. This may simply be because a BreadCrumb device has been
switched off, or its battery has died, or it may indicate a problem with the network, its deployment, the
local radio environment, or other factors.
3.1.2.3. NUMBER OF PEERS
A peer is simply another BreadCrumb device to which a BreadCrumb device has meshed. Data packets
are automatically routed through peers as necessary by the BreadCrumb devices.
