Installation Recommendations
• The most efficient way to install the DecisioNet hardware
infrastructure is in one pass through the store. Install the CBSs,
antennas, power cables, and data cables all at the same time
• Label all cables and document labeling for future reference.
• Neatness makes servicing the system much easier.
• Allow slack in cables, especially in receive antenna cables.
• Test the system as it is being installed. Refer to Chapter 7, "Testing
and Troubleshooting," for information on testing.
• Provide AC power that meets NCR requirements for the power
supplies.
• Test wiring as it is installed. Some installation problems are
extremely difficult to diagnose later.
• DecisioNet Release 3.0 requires the RF infrastructure to be
connected to the site's DecisioNet Software Controller to test the
infrastructure. Refer to the following for information on testing the
infrastructure and site certification:
• DecisioNet Implementation Guide (B005-0000-1250)
• DecisioNet RF Certification Utility Guide
• Certification/Re-Certification Site Survey Policy (497-0410343)
Chapter 3: Installing the Hardware Infrastructure 3-3
General Layout Instructions
• The cable length between any two devices (hub to CBS or CBS to
CBS) cannot exceed 100 m (328 ft.).
• The maximum number of Ethernet levels beyond the primary CBS
is three (3).
• The maximum total cable length is as follows:
Cable
Maximum Cable Length
Ethernet (primary CBS to last CBS in
chain)
300 m (984 ft.)
Power supply to last CBS in the chain
162 m (532 ft.)
• Use only NCR authorized communication cable.
• Communication cables must be secure and locked into their
connectors.
• The maximum number of CBSs per store is 40 except for model
7730-1013-9090 (Netherlands) which has a maximum of 12 CBSs
per store.
• If the communication cable is routed through an elevator shaft, it
must be in a conduit and the conduit must be connected to the
building ground.
• The minimum distance between a communication cable and a
fluorescent, neon, or incandescent light is 30 cm (12 in.).
Note: The minimum distance from red blown neon-type signs is 9.1 m
(30 ft.). See the “Neon Signs” section in Chapter 2 of the DecisioNet
Implementation Guide for information.
• All communication cable connections must be protected from
electrical and mechanical deterioration. The deterioration of
communication cable connections due to corrosion or electrolysis,
especially in a humid or corrosive atmosphere, may result in
electrical noise.

CBS Numbering
CBS’s are identified in the CBS Manager section of the DecisioNet CBS
configuration file (DNCBSCONFIG.XML) with a unique number (1-99)
and a host name or IP address. Using the numbering scheme shown in
the illustration helps identify the level in which the CBS is connected in
the topology when running diagnostic tests and analyzing diagnostic
logs. This scheme is as follows:
• Primary CBS = always 1
• Level 1 = CBS 11-13
• Level 2 = CBS 21-29
• Level 3 = CBS 31-57
CBS configuration details are described the “Setting the CBS IP
Address” section of Chapter 6, Configuring the DecisioNet System
Environment.
Chapter 3: Installing the Hardware Infrastructure 3-7
CBS Power Supply Cable Connections
The CBS Power Supply can support up to five (5) CBSs, however,
power requirements in EU/EC countries limit the number of CBSs
connected to a power supply to three (3). The following illustration

CBS to the next CBS.
2. On each end of the data cable, install the wires into an RJ45
connector as shown in the previous illustration and then crimp the
connector onto the cable.
3. Plug the RJ45 connector into data connector 1, 2 or 3 and into the
Uplink data connector of the next CBS.
4. Repeat steps 1 – 3 until all secondary CBSs are linked by a data
cable.
Chapter 3: Installing the Hardware Infrastructure 3-21
Connecting Power Supply Cables
Refer to the illustrations in the “CBS Power Supply Cable Connections”
section. Power supply cable routing is store dependent. The power
connector provides flexibility to connect additional CBSs in series from
one CBS to another or in parallel from a CBS to three other CBSs.
Connecting CBS Power Supplies to AC Power
Place the CBS power supplies with the host computer system, if
possible. Plug all power supplies into a common power strip so that
you can power them on and off at the same time for reset purposes.
In some cases, cable length restrictions may prevent you from
installing all power supplies in the same location. In this case, you
need to install a separately switched AC main circuit so that you can
still control the power supplies at the same time. If local electrical
codes or special circumstances require you to install more than one
switched AC main circuit for the power supplies, all the main circuit
switches should be in the same easily accessible location.
Do not install the CBS power supply in the ceiling.
1. Have an electrician install new AC receptacles if needed.
2. Do not plug the CBS power supply into an AC receptacle until
steps 1 – 6 in the next section are complete and the transmit
antenna is connected to the CBS.
Connecting CBS Power Supplies to CBSs
Each CBS power supply can power up to five CBSs as shown
previously in the store configuration illustration. The wiring is the
same for each group of up to five CBSs.
Follow these steps to connect a CBS power supply to each group of up
to five CBSs:
1. Cut a length of power cable that is long enough to reach from the
power supply to a CBS.
3-22 Chapter 3: Installing the Hardware Infrastructure
2. Splice the power cable wires to the pigtail supplied with the power

pairs: 1-2, 3-4, 5-6, 7-8 for each power cable connection at the CBS.
6. Plug the connector back into the CBS.
7. Insert the AC power cable into the power supply's AC receptacle.
8. Connect the AC plug to the AC power source.
Caution: To prevent damage to the transmitter, the transmit antenna
must be connected to the CBS before applying power to the CBS.
Chapter 3: Installing the Hardware Infrastructure 3-23
CBS Antennas Two types of antennas are available for the CBS:
• Transmit
• Receive
The transmit and receive antennas look similar, but have the following
differences:
• The transmit antenna has a screw-on reverse polarity SMA
connector and uses cable 1424-C424-0018 to connect to the CBS. The
other end of this cable has a reverse polarity TNC connector.
• The receive antenna has a BNC connector and uses cable
1424-C057-0180 to connect to the CBS. This cable has two BNC
connectors.
Note: With 100 mW CBSs, a 15 m (49 ft.) receive antenna cable
1416-C520-0150 must be used instead of the usual 18 m (59 ft.)
receive antenna cable.
Consider the following when installing antennas:
• Install the antennas at the same time you are installing the CBSs.
• On a dropped ceiling, mount the antennas from the T-bars. In an
open ceiling, hang the antennas from the roof trusses.
• When mounting the antenna, face the front of the antenna (the side
opposite the cable connector) towards the ESLs, with as few
obstructions between it and the ESLs as possible.
3-24 Chapter 3: Installing the Hardware Infrastructure
Installing CBS Antennas
The transmit antenna and receive antenna kits include the same
mounting hardware. The installation procedures for the transmit and
receive antennas are the same.
Mounting an Antenna on a T-bar
Note: Maintain a minimum distance of 9.2 m (30 ft.) between a
CBS's transmit and receive antennas.
To install an antenna on a dropped ceiling's T-bar:
1. At the desired location, install a T-bar hanger on the T-bar.
2. Screw the antenna onto the T-bar hanger.
3. Route the antenna cable through a 13 mm (1/2 in.) hole in the
ceiling tile or route it between the T-bar and the edge of the ceiling
tile.
Note: Do not allow debris from the ceiling tile to fall into the antenna
connector.
4. Install the cable onto the antenna connector.
5. Connect the other end of the antenna cable to the CBS.
6. Use cable ties to secure the antenna cable.

Sample HOSTS file:
# Copyright (c) 1993-1995 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows NT.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
