The IC certification number for the NCL1135 is 32251021662A.
To prevent radio interference to the licensed service, this device is
intended to be operated indoor s and away from windows to provide
maximum shielding. Equipment (or its transmit antenna) that is
installed outdoors is subject to licensing.
Federal Communications Commission
The NCL1135 complies with FCC Part 15 Regulations.
WARNING!
The FCC ID for the NCL1135 is OOX-NCL1100.
The transmitter of this device complies with Part 15.247 of the FCC Rules.
WARNING!
Operators must be familiar with the requirements of the FCC
Part 15 Regulations prior to operating any link using this
equipment. For installations outside the United States, contact
local authorities for applicable regulations.
Interference Env ironment
Manufacturers and operators of spread-spectrum devices are reminded that the operation of
these devices is subject to the conditions that:
• Any received interference, including interference from industrial, scientific, and
medical (ISM) operations, must be accepted; and
• These devices are not permitted to cause harmful interference to other radio services.
If the operation of these systems does cause harmful interference, the operator of the spreadspectrum system must correct the interference problem, even if such correction requires the
Part 15 transmitter to cease operation. The FCC does not exempt spread-spectrum devices
from this latter requirement regardless of the application. The FCC strongly recommends that
utilities, cellular stations, public safety services, government agencies, and others that provide
x APCD–NC003–2.0A
critical communication services exercise due caution to determine if there are any nearby
radio services that can be affected by their communications.
Operational Requirements
In accordance with the FCC Part 15 regulations:
1. The maximum peak power output of the intentional radiator shall not exceed one (1)
watt for all spread-spectrum systems operating in the 2.4000-2.4835 GHz band.
2. Systems operating in the 2.4000-2.4835 GHz band that are used exclusively for fixed,
point-to-point operations may employ transmitting antennas with directional gain
greater than 6 dBi, provided the maximum peak output power of the intentional
radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna
exceeds 6 dBi.
3. Stations operating in the 2.400-2.4835 GHz band that are used for fixed, point-tomultipoint operations may use transmitting antennas of directional gain greater that 6
dBi, provided the peak output power from the intentional radiator is reduced by the
amount in dB that the directional gain of the antenna exceeds 6 dBi.
4. Fixed, point-to-point operation, as used in Point 2, excludes the use of point-tomultipoint systems, omni-directional applications, and multiple co-located intentional
radiators transmitting the same information. The operator of the spread-spectrum
intentional radiator or, if the equipment is professionally installed, the installer is
responsible for ensuring that the system is used exclusively for fixed, point-to-point
operations.
5. The operator of a spread-spectrum system is responsible for ensuring that the system
is operated in the manner outlined in Interference Environment on page x and
Operational Requirements on page xii.

Warnings and Advisories
General Advisory
Operator and maintenance personnel must be familiar with the related safety requirements
before they attempt to install or operate the NCL1135 equipment.
It is the responsibility of the operator to ensure that the public is not exposed to excessive
Radio Frequency (RF) levels. The applicable regulations can be obtained from local
authorities.
WARNING!
This system must be professionally installed. Antennas and
associated transmission cable must be installed by qualified
personnel. WaveRider assumes no liability for failure to adhere
to this recommendation or to recognized general safety
precautions.
WARNING!
To comply with FCC RF exposure limits, the antenna for this
transmitter must be fix-mounted on outdoor permanent
structures to provide a separation distance of 32 cm (12 inc hes)
or more from all persons to satisfy RF exposure requirements.
The distance is measured from the front of the antenna and the
human body. It is recommended that the antenna be installed in
a location with minimal pathway disrupt ion by ne arby per sonnel.
WARNING!
Do not operate the NCL1135 without connecting a 50-ohm
termination to the antenna port. This termination can be a
50-ohm antenna or a 50-ohm resistive load capable of absorbing
the full RF output power of the transceiver. Failure to terminate
the antenna port properly may cause permanent damage to the
NCL1135.

spread-spectrum transceiver are controlled through the integration of a powerful
microprocessor.
• Architectural flexibility—WaveRider’s NCL1135 can be set up as a separate point-
to-point links, or in a mulitipoint configuration in which a single NCL1135 operating in
“master” mode can deliver data to and receive data from a maximum of 20 NCL1135
devices operating in “station” mode.
• User-configurable and -customizable monitoring—WaveRider’s NCL1135
operating system supports Simple Network Management Protocol (SNMP), which
allows for continual status monitoring of any NCL1135 in your network, and remote
upgrading.
• Low interference—WaveRider’s implementation of Direct Sequence SpreadSpectrum (DSSS) technology transmits signal information over a wide channel
bandwidth, which reduces the potential for interference with neighboring
communications systems. WaveRider’s NCL1135 design permits three master units to
operate in close proximity without interfering with each other. For example, three
master units supporting 20 station units apiece can operate in close proximity, thus
providing 60 end-user links.
• Software-enabled feature sets—WaveRider offers NCL1135 users an easy,
customizable upgrade path through software-enabled feature optioning.

1.3 About Spread-Spectrum Radio Technology
Spread-spectrum communications systems differ from conventional narrowband
communications systems because they use a much larger transmission bandwidth to send the
same amount of information.
There are two primary forms of spread spectrum—direct sequence and frequency hopping.
The NCL1135 uses direct-sequence spread-spectrum (DSSS). In DSSS systems, the
transmitted information, along with a digital spreading sequence, are used to modulate the
transmit carrier. The received signal is de-spread using the same digital spreading sequence,
and the information recovered.
Although spread spectrum appears complex and uses a wider bandwidth, DSSS offers the
following advantages for its use:
• Reduced power spectral density—Spreading over a wider bandwidth reduces the
spectral density (power per Hz of bandwidth) of the transmitted signal, allowing
simultaneous operation of many spread spectrum systems in the same frequency
band and geographic area. The reduced spectral density also allows you meet the
regulatory emissions re qui rements in frequency bands such as the ISM band.
• Transmission security—It is technologically more difficult to surreptitiously recover
(or jam, in the case of military communications systems) spread-spectrum signals
than it is to recover conventional narrowband signals.
• Interference suppression—The same mechanism that de-spreads the desired
signal in the receiver, also spreads undesired signals, which then appears to the
receiver as low er levels of RF noise.

2 Network Considerations
This section provides an overview of the network considerations that you should make before
beginning to implement an NCL1135 network. These network considerations include the
following:
• configuration
• mode: bridging or routing
• planning
2.1 Network Configuration
The NCL1135 can be deployed in three different network configurations:
• point-to-point
• repeater
• point-to-multipoint
Before deploying the system, you must determine the required network topology.
APCD–NC003–2.0A 5
2 Network Considerations
2.1.1 Point-to-Point
In a typical point-to-point application, shown in Figure 2, unit A communicates direct ly with uni t
B. You can implement the link in either bridging or routing mode.
2.1.2 Repeater
You can set up a repeater by using two NCL1135 units back-to-back.
Figure 2 Point-to-Point Application
Ethernet EthernetRadio
NCL1135 NCL1135
AB
In the configuration shown in Figure 3, unit A communicates with unit B via the back-to-back
NCL1135 repeater configuration of units C and D. You must use different frequencies for each
leg of the path. Use this configuration to circumvent large obstacles in the radio link path, or
when the link from unit A to unit B is too long to provide reasonable signal levels and data
throughput.
Figure 3 Repeater Application
Ethernet Radio Ethernet EthernetRadio
NCL1135
ACD
NCL1135 NCL1135 NCL1135
B
In this configuration, the effective data throughput from unit A to unit B is the same as the
lessor data throughput from unit A to unit C or unit D to unit B. That is, the throughput through
a series of links will be that of the slowest link.
You can implement this configuration in either bridging or routing mode.

2 Network Consider ations
2.1.3 Point-to-Multipoint
Figure 4 shows an example point-to-multipoint configuration. The master, unit A, sends and
receives messages to and from NCL1135 stations. In this configuration, the throughput of unit
A is shared among the stations.
Although stations may receive communications from other stations, because of RF
propagation conditions, the stations are programmed to accept messages only from their
designated master.

2.2 Bridging and Routing Ne twork Conf igurations
2.2.1 Point-to-Multipoint Bridging Network
In a point-to-multipoint network configuration, each NCL1135 must be configured as either a
bridge or router, not a mix of both operational modes. Figure 5 shows the configuration of a
typical point-to-multipoint bridging network.

ID on each station is set to the unit ID for Unit A. If a unit is not in the Master Remote Station
List and does not have the Master ID set to the unit ID for unit A, it will not be able to join the
network.

3 Configuring the NCL1135
This section describes the steps required to initialize and configure the NCL1135 for use as
either a bridge or router, including the options available for routing and system monitoring.
NCL1135 users can perform these steps three ways:
• Telenet command line interface (CLI)
• Windows 95/98 graphical user interface (GUI)
• Internet Explorer/Netscape Communicator web browser
Before you begin these procedures, you should become familiar with the conventions used to
display the command-line syntax used in this manual. See NCL1135 Command-Line Syntax
Conventions on page 57. Table 7 on page 58 defines the keyboard shortcuts for entering
commands and requesting help.
NOTE: The following section describes the procedures for configuring
the NCL1135 via Telnet CLI. To download the Windows 95/98
GUI application, or more information on configuring the NCL1135
via web browser, visit WaveRider’s website at:

3 Configuring the NCL1135
3.1 Connecting and Initializing the NCL1135
WARNING!
Antennas and associated trans mission cable must be installed
by qualified personnel. Failure to terminate the antenna port
correctly can permanently damage the NCL1135. WaveRider
assumes no liability for failure to adhere to this recommendation
or to recognized general safety precautions.
1. Attach the antenna or a 50-ohm load to the antenna connection on the back of the
NCL1135. Do NOT plug the NCL1135 to the power outlet until you have the antenna
or load connected.
NOTE: The NCL1135 is factory preset with the radio transmission
capabilities disabled to prevent equipment damage. However, as
a general precaution, WaveRider recommends that you always
connect the antenna or load before
source.

3. If you are using a terminal-emulation package, such as HyperTerminal, start the application.
4. In the terminal-emulation application, select the communications port that you are
using to connect to the NCL1135.
5. Configure the application using the following settings:
• 9600 bps
• 8 data bits
• no parity
• 1 stop bit
• no flow control
6. Plug the NCL1135 into a 110 or 220 V AC power source using the power cord
provided with the unit. The NCL1135 begins an initialization sequence displaying
progress messages on the terminal screen.
When it completes initialization, it displays a message to indicate that the system is
operational and the PASSWORD: prompt appears.
7. At the PASSWORD: prompt, press ENTER. The NCL1135 comes factory-configured with no password.
8. Change the password for the NCL1135 by following the instructions in Changing the
NCL1135 Password, on page 14.
9. Change the system name in the NCL1135 as described in Setting the NCL1135
System Name, on page 15.
10. If the NCL1135 had been configured for use elsewhere in your network, reset the unit
by following the instructions is Resetting an NCL1135 to Factory Settings, on page 15.
If the NCL1135 is a factory-configured unit, you can omit this step.
The NCL1135 is now ready to be configured for your network.

3 Configuring the NCL1135
3.1.1 Changing the NCL1135 Password
You must be successfully connected and logged into the NCL1135.
For security, we recommend that you set the password for each unit in your network to a
unique password and that you record the password on the Configuration Data Record for the
group. Refer to Appendix E for a copy of the NCL1135 Network Group Configuration Data
Record.
1. At the NCL1135> prompt, type <system password>.
2. At the Enter Current Password: prompt, type the old password.
3. At the Enter New Password: prompt, type the new password.
4. At the Verify password: prompt, type the new password again.
TIP: Use a maximum of sixteen (16) alphanumeric,
ASCII charact er s. Pa ss w or ds are ca se-sensitive . Fo r
example, “abc” is not the same as “aBc”.
The system will display a message that your password has been successfully
changed.
5. Type <write> or <save> to save the settings to memory.
Your session to change the password may be similar to the following example session:
NCL1135> system password
Enter Current Password: *******
Enter New Password: ****
Verify password: ****
System password has been changed.
NCL1135>
CAUTION: Remember to record the password in your Data Configuration Record.
Unlocking the NCL1135 can be a complicated process. If you have forgotten the
password, contact the WaveRider Customer Support Centre for assistance.
