Glossary
A
Active Group
The devices available on a communications link.
Active Group tree
A visual representation of the active devices on the
Rover screen.
Active Mode
Use the active mode when using Rover to configure a
Trane peer-to-peer network. Do not enter the active
mode on third-party networks or on Trane networks
with Tracker controllers that have not yet been
installed. In the active mode, you can use Rover to
perform network management tasks, including
creating bindings and cleaning up links. See also server-
connected mode, passive mode.
Auto-identify
An option in Rover that automatically identifies a device
when its service pin button is pressed. If Rover is
running on a site, you can press the service pin button
on a device communicating on the link. When you
return to your laptop PC, the device is selected in the
Active Group tree, and the device status appears in the
workspace.
Auto-wink
An option in Rover to automatically wink a device when
the service pin button is pressed on that device. If you
have Rover running on a site, you can press the service
pin button on a device. If the status LED blinks, you
know that device is communicating without having to
go back to your laptop PC.
B
BCU
Building control unit. A Tracer Summit field panel that
coordinates system-level control of multiple unit
controllers. The Tracer Summit PC Workstation
communicates with BCUs to monitor and control sites.
Binding
Bindings allow two or more devices to share common
information, such as the same setpoint or zone
temperature sensor. Bindings link a network variable in
one device with a network variable in another device to
share data between the devices.
C
Communication Key
The communication key provides temporary communi-
cations capabilities to stand-alone devices. Attach the
communication key to the device while it is communi-
cating and remove it when the work is complete.
Configuration
The configuration is the set of parameters downloaded
to a device that condition the device and determine its
function of operation. Typically, the device installer sets
these parameters.
CRC (Cycle Redundancy Check) Error
CRC errors are a means of verifying the accuracy of
transmitted data by adding on summary data values.
They occur when the summary data value sent is not
the same as the summary data value received.
D
Device
In this user guide, device refers to any controller that
uses the LonTalk communications standard.
Discover
The Discover command checks the active link for com-
municating devices and adds any new devices to the
Active Group tree.
Domain ID
The domain ID is the network domain on which a
device communicates.
F
Flash Download Wizard
The Flash Download Wizard downloads an image file to
a controller to update its firmware. The wizard can
perform flash downloads only to controllers that have
flash memory. See also image file.
