Glossary
Antenna
A device used to transmit and receive RF communication between
a CBS and ESLs. One transmit and up to four receive antennas may
be attached to each CBS. Antennas are usually installed on the
ceiling.
API (Application Program Interface)
A set of functions that can be used by the application software to
access the functionality of the DecisioNet Software.
Attachments
Mounting devices used to attach ESLs to shelf rails.
Base Runtime Software
A software application for the DecisioNet System that runs on the
DecisioNet Software Controller and is not dependent on the type of
POS system used. The Base Runtime Software controls the core
DecisioNet functionality such as initialization of a ESL, display of
price on an ESL, and diagnostics.
This software also provides a set of standard API functions that can
be used to interface with the ESL Application Software and other
software controlling the POS system.
Bedcheck
A background function that verifies ESLs are working properly. If
an ESL does not respond to a bedcheck message, an error is
recorded.
G-2
Glossary
CBS (Communication Base Station)
CBSs receive and transmit data and control functions to the ESLs.
Up to 40 CBSs can be installed in a store. One CBS is defined as the
primary CBS and the others as secondary CBSs. CBSs are usually
installed in the ceiling.
CBS Power Supply
This external AC/DC converter supplies DC power to a maximum
of five CBSs. An additional CBS Power Supply is required for each
additional group of 5 CBSs. Power requirements in the EU/EC
countries limit the number of CBSs connected to a power supply to
three (3).
Coverage Area
An area within a store where there is reliable RF communication
between CBSs and ESLs. More than one CBS is required in a large
store to attain adequate transmission reliability.
Descriptor Symbols
One symbol on the ESL's LCD indicates when the ESL and CBS are
out of synchronization, and another symbol indicates when the
ESL's battery is low. The other symbols on the display are available
for the retailer's use.
DecisioNet Database
A MySQL database used to store information relative to all ESL
management.
DecisioNet Software Controller
This refers to the In-Store Processor (ISP) or a Dedicated PC (DPC).
This is the computer physically connected to the primary CBS that
sends price information from the PLU file to the DecisioNet System
for display on ESLs.
Glossary
G-3
Downlink
A CBS sends data to an ESL in a downlink message. Examples of
downlink messages are Bedcheck, Price Update, Load Memory,
and Change Display Register.
DPC (Dedicated Personal Computer)
This PC, acting as the ESL controller, reads the customer's PLU file
from the In-Store Processor/POS system via a LAN connection and
communicates the information to DecisioNet System.
Error Log
This module of the DecisioNet Software records and displays
communication errors between the ISP or DPC and an ESL.
ESL (Electronic Shelf Label)
An ESL is the device attached to the store shelf that displays
information for the customer.
ESL Removal Tool
Also called an ESL puller, this tool is used to remove ESLs from
shelf rails and clips.
ESL Serial Number
During manufacture, a distinct 8-digit (32-bit binary code) number
is assigned to each ESL and stored in the ESL's RAM. The serial
number and its barcode equivalent (Code 39) are printed on the
right side of the ESL. The serial number and the bar code are blue
on a freezer ESL and black on all other ESLs.
ESL Standalone System
A system that runs the DecisioNet Software on a dedicated PC
separate from the ISP. In this situation the DPC has a copy of the
store data base and communicates with the ISP to receive
maintenance (price update) data.
G-4
Glossary
ESL Table
An area in the DecisioNet Database created during the initial
DecisioNet System installation that links ESLs to PLU items. This
table also contains other data used to define the attributes of each
ESL.
Initialization
The process by which an ESL is registered in the DecisioNet data
base, associated with a particular product, and synchronized.
IP (Internet Protocol)
IP Addresss
An address format (xxx.xxx.xxx.x) used to communicate with
devices or components in an network. The format includes
network IDs, subnetwork IDs, and host IDs.
ISP (In-Store Processor)
The computer in the store that contains the price database used by
the POS system. The ISP integrates PLU information into the
DecisioNet System.
LCD (Liquid Crystal Display)
The type of display in an ESL.
MAC (Medim Access Control)
A communications protocol. The MAC protocol is used to provide the
data link layer of an Ethernet LAN system.
PC (Personal Computer)
Pre-ESL Table
A data file used to is create an ESL Table.
Glossary
G-5
Promotional Message
Promotional message(s) such as "SAVE," "OFF," and "FOR SALE"
can be displayed on the ESL alternately with the price
Register Data
These messages, such as stocking information and aisle number,
may be used by store personnel. They can be displayed on the ESL
by pressing a micromotion button hidden behind the front label or
by transmitting an instruction from the processor.
RF (Radio Frequency)
Shelf Rail
A device which can be attached to the existing shelf/gondola to
secure several ESLs to the shelf and protect them from accidental
damage and from theft.
Store ID
A unique number is assigned to each store and used by the
DecisioNet System to prevent unintentional transmission of signals
between stores.
Tag
A tag, also referred to as an Electronic Shelf Label (ESL), is the
device attached to the store shelf that displays information for the
customer.
Time Slot
A unit of time assigned to each ESL during which a CBS transmits
either a downlink message to an ESL, or receives
acknowledgements (ACKs) back from an ESL. Each CBS is assigned
2 time slots.
G-6
Glossary
TOD (Time Of Day)
A clock used by the DecisioNet System to trigger display changes.
Uplink
An uplink is an acknowledgment message (ACK) sent from an ESL
to a CBS in response to a downlink burst.
