GENERAL

The Carrier wireless transceivers enable connection to the
Carrier Comfort Network (CCN) in areas where standard wir­ing cannot be used. The wireless transceiver can be pl ugged
into any standard serial port (RS-232 or RS-485) on a wide
variety of devices to provide CCN communications.

Wireless bus extension is only recommended if there are
no CCN secondary busses. Wireless extension of secondary
busses is not recommended.

The wireless transceiver operates in th e license-free portion
of the FCC designated ISM (industrial, scientific, and medical)
frequency band at 2.4 GHz. It is ideal for transmissions over
long distances: up to 1500 ft indoors and line-of-sight to the
horizon outdoors. Data is transmitted reliably and securely
with wireless communications which enable service-i nterface
mobility.

The wireless transceivers operate in point-to-point pairs and
broadcast networks.

Two wireless transceiver kits are available from Carrier.
The 33CNWIRMOD kit contains the following: 2 wireless
transceivers, 2 power supplies, 2 RS-232 to RS-485 converters,
2 RS-232 cables, Carrier Wireless Transceiver Configuration
Manager, 2 antennas, and a loopback connector.

The 33CNSNGMOD kit contains the following: wireless
transceiver, power supply, RS-232 to RS-485 converter,
RS-232 cable, and an antenna.

In order to communicate outdoors between structures, an
additional outdoor antenna (part number 33CNOAANT1) is
required for each wireless transceiver.

Frequency Hopping —

The Carrier wireless transcei v­ers use Frequency Hopping Spread Spectrum (FHSS) technol­ogy to ensure secure, reliable long-range data transmissions.
Frequency Hopping Spread Spectrum technology was devel­oped by the U.S. military to prevent interference or intercep­tion of radio transmissions on the battlefield.

Frequency hopping devices concentrate their full power into
a very narrow signal and randomly hop from one frequency to
another within that spectrum up to 200 times per s econd. If they
encounter interference on a particular frequency, the devices re­tain the affected data, randomly hop to another point on the
spectrum, and continue transmission. There are always spaces
without interference somewhere in the allotted radio spectrum.
A frequency hopping device will find those spaces and com­plete a transmission where other wireless technologies fail.

Carrier wireless transceivers use demand-based frequency
hopping where RF (Radio Frequency) is only transmitted when
there is data avai lable to tr ansmit. The initiat ing transc eiver is
termed the master and the receiving tr ansceiver is called the
slave. Any device (host or remote transceiver) can be a master
or a slave depending on which device initiates the data transfer.

Transmit Power Control —

Wireless devices in close
proximity often experience desensing or overloading. Carrier
Wireless Transceivers minimize this problem by providing ad­justments in the Power Level Feedback Control Loop based on
the time-averaged Received Signal Strength Indicator (RSSI)
values and the Actual Power Level Setting as shared betwe en
both devices during a communication session.

Security —

Frequency hopping is inherently more secure
than other RF technologies. In addition, each transceiver has a
Carrier ID set in the firmware shipped straight from the factory.
As the user configures each transceiver, additional network ID
numbers may be provided and varying hop tables for indepen­dent networks may be assigned. The combination of firmware,
software IDs, and frequency hopping technology ensures safe
and secure data transmissions. Carrier wireless transceivers
also support your data encryption software.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

PREINSTALLATION

Fig. 1 — Loopback Configuration

Every installer should perform site evaluation prior to
installing the transceivers. In order to perform this evaluation
the following minimum equipment must be purchased from
Carrier. The two modem starter kit (33CNWIRMOD) is re­quired to begin performing a site evaluation. The following
components are in the two modem kit:

2 — standalone transceivers

2 — high gain omni-directional antenna

2 — transceiver power supplies

2 — RS-232 to RS-485 converters

2 — 9-pin RS-232 cables

1 — copy of transceiver configuration software

1 — loopback connector

If the set up requires outdoor antennas they can be pur­chased from Carrier as part number 33CNOAANT1.

High gain directional antennas may be required t o establish
reliable communications. Directional antennas can be pur­chased directly from the antenna vendors described in the an­tenna selection and location section of this manual.

Site Evaluation Testing — Loopback Test —

order to perform a loopback test the transceivers must be con­figure Broadcast Remote-to-All. See the Remote-to-All config­uration section of this manual.

To perform a loopback test it is necessary to connect each
modem (one host and one remote) to its power supply. Then
connect a PC with the Configuration Manager software to a
modem using the 9-pin RS-232 cable provided. Lastly , connect
the second modem directly to the loopback connector. See
Fig. 1.

Perform the loopback test by executing the following steps:

1. Position the modems directly on top of each other and re­move both modem antennas if connected. Use a host and
remote pair for this test.

2. Run the Configuration Manager on the computer and log
into the software using the username “oem” and pass­word “oem”.

3. Select the Loopback Test program tab within the Config­uration Manager software.

4. In the Test String dialog box enter a text string such as
TESTING.

5. Using the pointer place a check in the Test check box.

6. Using the pointer select the Instantaneous RSSI option.

7. Press the Start button on the screen to begin sending the
T est String.

8. The TX pane should start displaying the Test String at
regular intervals. If the string is be ing received and sent
back by the remote transceiver the RX pane should dis­play the same text screen. If the Test String is successfully
transmitted through the loopback connector with the
transceivers on top of each other proceed to Step 10.

9. If the RX pane displays “Timeout?” each time the Test
String is sent then perform the following tests:

a. Verify that both transceivers are properly config-

ured for Broadcast Remote-to-All operation.

b. Verify that both antennas are removed from the

transceivers (NOTE: if antennas are connected and
located too close together the two antenna fields
will cancel each other out).

c. Verify that cycling power to the modems shows the

3-flash blink as described in the Getting Status sec­tion of this manual.

In

10. After successfully establishing communications between
the two transceivers locally, locate the transceivers in
their desired locations and repeat Steps 2 through 8.

11. If the text string is being received and sent back by the re­mote transceiver the RX pane should display the same
text string. If the text string is successfully sent and
received the transceiver and antenna locations are
acceptable. The green sync light should remain lit once
the first data is se nt.

12. If the RX pane displays Timeout? each time the Test
String, is sent them perform the following tests or the
sync light will not remain on:

a. Verify that both antennas are properly installed on

the transceivers.

b. Reposition the transceivers such that the green sig-

nal strength bar is as long as possible. Normally
signal strengths above .5 are required for reliable
communications (see Antenna Selection and Loca­tion section).

c. Attempt to utilize directional antennas in order

to obtain reliable communications (see Antenna
Selection and Location section).

INSTALLATION

Hardware Installation —

ceiver(s), count and check all of the delivered equipment. A
power supply and an antenna is required for each transceiver.
The transceiver will be attached to either RS-232, RS-485 con­verter to a PC or laptop. Prior to installation on the desired de­vice, all transceivers must first be connect ed to and configured
with a PC.

Carrier recommends mounting wireless transceivers inside
a building structure. Refer to Table 1 for temperature and
humidity criteria when mounting transceivers. If an antenna
is mounted outdoors or the CCN network extends outside of
a building, use of an RS-485 surge suppressor is recommend­ed. Refer to CCN installation and Start-up Instructions for
lightning/surge protection recommendations.

To install the transceiver, perform the following procedure
and refer to Table 1 for hardware specifications:

1. Insert the power supply male connector into the corr e­sponding female connector slot on transceiver chassis.

2. Insert power supply plug into power (i.e., power outlet ).
Verify LEDs 1 and 2 on front panel blink three times.
LED 1 should remain lit.

3. Attach the antenna to the transceiver.
NOTE: The antenna connection i s a re verse t hread SMA

connection. It must be turned counterclockwise to attach.

4. Attach the male connector on the RS-232 cable to the
matching serial port on the rear panel of the transceiver.

5. Connect the other end of the RS-232 cable to the match­ing serial port on the device.

In order to configure any
transceiver, a 9-pin RS-232 cable must be used. This is neces­sary because Pin 4 is used to transmit the configuration data
into EEPROM and other pins are used during the configuration
process as well (see T able 2). A 9-pin RS-232 cable is included
with all stand-alone transceivers.

The 9-wire cable must be used in the following cases:

• when using the Configuration Manager to initialize/

setup a transceiver

• when a Carrier CCN Interface is connected via the

RS-232 port

• when field upgrading the transceiver software

Software Installation

The software has the following requirements:

• Windows® 95/98 or above (depending on software

used)

• Pentium processor 233 MHz or higher

• 1 available RS-232 serial port

• Minimum 32 MB DRAM

• Maximum 20 MB hard disk space for Configuration

Manager

CONFIGURATION MANAGER — The Conf ig u r a tion Man­ager program is used to configure all transceivers.

To install the Configuration Manager software, perform the

following procedure:

1. Make sure all Windows applications are closed.

2. Insert the Installation CD-ROM into the appropriate
drive. Select folder “CONFIG_111300” then select
“Disk 1”.

3. Open the contents of the drive using Windows Explorer
or My Computer.

NOTE: Take note of all warnings and notes that refer
to computer/software requirements when running this
program.

4. Double-click on “Setup.exe.”

5. Follow the on-screen instructions.

Antenna Selection and Location —

effect signal strength:

1. Location
a. Line of sight between antennas is always preferred.

Several factors

b. Locations directly adjacent to walls or other

structures should be avoided for omni-directi onal
antennas.

c. Barriers between antennas should always be con-

sidered (see barrier information on page 16 for
degree of penetration).

d. Antennas should be moved within the desired

space to determine if a better location within the
desired area can be found.

2. Polarization
a. Antennas must be oriented in the same plane. For

example, omni-directional stick antennas must
both be vertical in the same plane in order for reli­able signal reception.

b. Directional antennas must be oriented in the same

plane utilizing the vertical pole identification on
the antenna.

3. Omni-directional vs. Directional
a. Omni-directional antennas provide essentially

equal signal strength around the antenna.

b. Omni-directional antennas can receive a signal

coming from virtually any direction in relation to
the antenna as long as polarization is not a factor.

c. Directional antennas provide greater signal

strength in the direction that the antenna is
oriented.

d. Directional antennas are labeled with a vertical

pole for proper orientation with both omni­directional and directional antennas.

e. Directional antennas should be pointed in the

direction of the receiving antenna.

f. Directional antennas will not receive any signals

coming from behind the antenna.

g. Directional antennas should be rotated to deter-

mine if bouncing the wireless signal can be utilized
in order to achieve wireless communications.

h. For best results it is recommended that a direc-

tional antenna be used in conjunction with an
omni-directional antenna. With this setup signal
strength is improved while antenna lin eup is fairly
straightforward.

Antenna Installation —

Antennas must be connected
to each transceiver for proper operation. Without an antenna,
two units will not communicate. The higher the gain of the an­tenna, the longer the range of the transceiver signal. All Carrier
transceivers ship with a 5 db omni-directional 9-in. antenna.
An outdoor antenna is also available from Carrier.

Carrier transceivers are designed to be used only with cer­tain antenna products. Other higher gain directional antennas
may be purchased through an approved Carrier supplier. Con­tact Carrier for additional information.

Installation onto a CCN Bus —

Use the RS-232 to
RS-485 converter to install transceivers directly onto an
RS-485 network. An RS-232 to RS-485 converter and power
supply is supplied with each transceiver.

1. Separate the RS-485 converter’s housing with a flat blade
screw driver .

2. Install jumpers in all 5 terminals.

3. Wire the CCN (+) to screw terminal Pin 1, and CCN (-) to
screw terminal Pin 2. See Fig. 2.

4. Cut the power plug off of the power cube 6 in. from the
end.

5. Wire the ground wire of the power supply wire to screw
terminal Pin 5 a nd the posi tive (wire wi th white line) to
screw terminal Pin 6. See Fig 2.

If a transceiver is used to connect directly to a comput er, an
RS-232 to RS-485 converter is not required. Only the 9-pin
cable (supplied) is used.

NETWORK TOPOLOGY

The Carrier transceivers support the Broadcast Network
topology . Each transceiver can be configured via its Configu ra­tion Manager to work this topology . The transceiver’s Configu­ration Manager controls how the transceiver transmits and re­ceives data as connected to the device. (See Fig. 3-5.)

Wireless communication signals can be adversely affected
by physical and/or electrical interference. Carrier wireless
transceivers should NOT be installed in applications where
temporary loss of communications cannot be tolerated by
the control system. Suitable applications include equipment
monitoring, alarm monitoring, control overrides and tem­porary service connections.

Networks —

require a wide range of networking options. The network
topologies consist of more than two transceivers and may have
a PC to host a network of devices. The PC or network devices
are each physically attached to a transceiver.

WIRELESS SERVICE TOOL — The wireless Service Tool
setup allows a CCN service technician t o install, commi ssion,
and troubleshoot from any location in the building. All CCN
elements on the primary bus are accessible. The wireless con­nection allows the technician to utilize a laptop computer to
perform all Service Tool functions from anywhere within the
range of wireless communication. If t he transceiver is locat ed
on a rooftop, it is possible to gain wireless acc ess to the build­ing from several miles away.

NOTE: Wireless buss extensions on CCN systems with sec­ondary buses are recommended for temporary use only. Per­manent use is NOT recommended.

WIRELESS BUS EXTENSION — The wireless bus exten­sion setup allows a bus to be extended to a remote location
through the use of the wireless transceivers. This set up can be
used to connect two portions of a CCN bus when physical wir­ing cannot be used or is not cost effective. This set up may also
be used to connect controllers in two different buildings by
placing the transceiver on the roofs of the buildings. This set up
is not recommended for CCN systems that contain secondary
buses.

Wireless links can only be used to extend a CCN primary
bus (bus D). Do not use bridges when using a wireless link.
Utilizing this primary bus wireless connection to access CCN
devices through a bridge will cause communication messages
to be generated on the primary bus.

The wireless bus extension setup allows primary bus to be
extended to a remote location through the use of wireless tech­nology. This set up can be used to connect two portions of a
CCN primary bus when utilizing physical wire may be a costly
or difficult task. This set up may be used to connected control­lers within a building or to another building by placing the mo­dems on the roofs of the structures.

A wireless bus extension on a CCN primary bus is only rec­ommended if there are no CCN secondary busses. If CCN
bridges are installed a wireless extension of the primary bus is
not recommended.

BROADCAST NETWORK — In a Broadcast Network, data
is sent out by one transceiver (sending transceiver) and re­ceived by an unlimited number of remote devices simulta­neously. These devices must be intelligent enough to recognize
relevant messages and recover lost or corrupted data. Broad­cast Networks operate solely as configured by the Configura­tion Manager.

Transmissions sent by the sending transceiver can be re­ceived by every remote unit in its associated network. Trans­missions by remote units can be received by every other unit in
the network that is within range. Broadcast mode is especially
useful to applications where you must transfer the same infor­mation to all units at once. (See Fig. 3.)

Broadcast mode is intended primarily to be a RS-485 net­work wire replacement. It is especially useful i n adding new
equipment to systems where there is a RS-485 connection. The
RS-232 to RS-485 converter is needed to configure transceiv­ers for RS-485 devices.

An example of the broadcast set up would be a wireless bus
extension to multiple buildings. The wireless bus extension set
up allows any primary bus to be extended to a remote location.

Passwords and Access

LEVELS OF ACCESS — There are two levels of access:
OEM and USER. Each level has access to different sets of
fields in the Configuration Manager. A User has the lowest lev­el of access and is only able to change parameters in some of
the fields available to OEMs. OEMs have access to all func­tions. See Tabl e 4.

All transceivers are shipped with OEM access. It is up to the

administrator to assign user privileges from that point on.
PASS WOR DS — Change the password as frequently as you

desire. A password consists of any combination of numbers or
letters up to 29 characters. Contact Carrier if a new password
file is needed. All units are shipped with “oe m” as the pass­word. It is recommended for security re asons to change your
password from the factory setting.

Depending on access level, you have User or OEM privi­leges. The dialogs that appear and the options available vary by
privilege.

NOTE: All units are delivered with OEM privileges.

A Hop Table is a listing of fre­quencies in a given spectrum that are used for communication.
Data is sent to each frequency in the table in a hopping pattern.
Hop Tables provide improved security and the ability to avoid
localized noise sources. There are 101 possible Hop Tabl es in
your transceiver (this number may vary for i nte rnational trans­ceiver models). These are subdivided into five completely in­dependent, non-overlapping Hop Table sets, each with no more
than three consecutive frequencies. Each individual network
can only utilize one Hop Table.

ENTERING HOP TABLE NUMBERS — Hop Table num­bers can only be entered or changed by using the Quick Con­figuration wizard.

Enter the desired identification numbers. See Assigning IDs

section for acceptable parameters. Select a Hop Table (0 to

100). The Hop Table selected must be the same for all trans­ceivers in a Point-To-Point or a Network. This number speci­fies a table of predefined frequencies, which the transceiver
will use for transmitting and receiving. If multiple separate net­works exist in the same area, each network should have a
unique Hop Table number to avoid RF collisions. Depending
on which network is selected in the previous screen, certain ID
fields may be grayed and inaccessible.

If multiple isolated wireless networks are installed in the
same area, it is recommended that hop tables 1-5 be used
sequentually.

VALIDATING THE HOP TABLE — This command veri­fies the integrity of the Hop Table stored within the transceiver .
The Hop Table in the transceiver is compared to the Hop Table
with the same number in the Configuration Manager database.
The Advanced Settings tab provides the selected Hop Table
number and whether the Hop Table has passed validation and
the first and last indices used for the Hop Table. Index values
are set to meet the requirements of the country in which the
transceiver is deployed for a minimum number of hop frequen­cies. These values can not be changed to avoid violating coun­try regulations. T o validate the Hop Table, from the Commands
menu, select Validate Hop Table.

SPECIFYING HOPPING PARAMETERS — You can cus­tomize Hop Table parameters by setting some features avail­able from the Advanced Settings tab.

Max No Data

— (Adjustment of these settings is not

recommended.)

Max No Data is the number of hop cycles that must pass
during which no data was received and no dat a was available
for transmission before a session can be declared down. It is
used as the trigger to end a session. After a certain number of
Frames No Data between both units, the master will terminate
the current session/link.

Max Bad Hop

— (Adjustment of these settings is not

recommended.)

Max Bad Hop is the number of data frames with errors re­ceived before a link is considered bad. This is the trigger to
stop the current link and wait for a random standoff period
(approx. 0.5 to 3 seconds). This is due to the assumption that
after 4 consecutive bad hops (system default but can be
changed), the link has been lost — either due to interference or
lost synchronization. By waiting a small amount of time before
attempting to reestablish the link, the obstruction (i.e., noise
source) may have moved somewhere else.

10

Session Holdoff

Fig. 16 — Quick Configuration Window

— (Adjustment of these settings is not

recommended.)

This will only be enabled for a host transceiver and is re­quired to manage the communication from multiple remotes. It
prevents a host unit from starting a new session until it com­pletes its current session. It keeps other devices from establish­ing a session with the host until the host has completed its cur­rent session with a particular device.

Assigning IDs —

Using a combination of firmware and
software assigned IDs, the security of the data is ensured. Some
IDs can be modified and others cannot depending on your
privileges. The IDs are all accessed either via Quick Configura­tion or the General Tab. See Fig. 16 and Table 5.

A number that identifies the network and
makes it unique from other networks in the
area. All units in a network must have the
same Network ID. The Network ID allows
the user to have multiple networks within
the same transceiver space. There are up

Unit Testing —

You can te st the operation of transceivers
in a variety of ways using the Configuration Manager. The in­structions in this section assume that the Configuration Manag­er is correctly installed and the transceiver is properly connect­ed to your PC.

The test string is transmitted to the Destination Unit and
looped back to the Source Unit. The RX Pane shows the test
string as received by the transceiver connected to the computer
after being loopbacked from the remote transceiver. If no data
is received within the timeout period the message “Timeout” is
printed in the RX Pane. The TX Pane shows the test string as
typed in the dialogue box.

T o perform a communication link test it will be necessary to
use two Carrier wireless transceivers, two antennas, a loopback
connector and a computer.

Perform the following tests:

• Terminal mode

• Loopback test (Stand-alone model only)
TERMINAL MODE TEST — The Terminal Mode tab pro-

vides a simple terminal interface from which data can be sent
between two units configured as a Broadcast Remote-to-All
Host and Remote Pair. Anything typed in the input field of
transceiver no. 1 will immediately be transferred to transceiver
no. 2. The data is displayed in the transmit pane for transceiver
no. 1 and the receive pane for transceiver no. 2. (NOTE: You
will only see received data if the destination transceiver is con­nected to a PC with Configuration loaded and open or if the
destination PC’s transceiver has a loopback connector .)

What Y ou Need:

• Two transceivers (A and B) configured as a host to

remote. The Source Unit ID of unit A equals the Desti­nation Unit ID of unit B and vice-versa. In addition, both
units must have matching Vendor ID numbers, Network
ID numbers and Hop Table numbers.

• One of these units is connected to a PC with the Config-

uration Manager loaded.

Test Communications Between Units:

1. Open the Configuration Manager. See Fig. 17.

2. Click the T erminal Mode tab.

3. In T est String, enter some text.

4. Click Resend.
The test string is transmitted to the Destination Unit.

LOOPBACK TEST — The Loopback Test screen allows
you to perform two functions; to test that two units can com­municate and to determine the best placement of one unit rela ­tive to another based on received signal strength. This test is
only used for stand-alone models.

What Y ou Need:

• Two transceivers (A and B): configured as a Broadcast
Remote-to-All and Host Pair. The Source Unit ID of unit
A equals the Destination Unit ID of unit B and vice­versa. In addi tion, both units mu st have matching Ven­dor ID numbers, Network ID numbers and Hop Table
numbers. Transceiver A is connected to a PC loaded
with the Configuration Manager.

NOTE: Test also works with host/remote set up.

• Loopback connector: Transceiver B (the one not con­nected to the PC running this program) must have a
loopback connector (pins 2 and 3 of the serial port tied
together) on the serial port o f the remote unit. A loop­back connector is delivered with all demo and developer
kits.

NOTE: Connect loopback connector to remote units if using a
host to remote se t up.

Test Communications Between Units:

1. Open the Configuration Program. See Fig. 18.

2. Click the Loopback Test tab.

3. In T est String, enter some text.

4. Enter the desired criteria in other fields in this group. The
default values are recommended for t his type of testing.
The minimum for Repeat Every field is 100 msec.

5. Click Start.

Test the Placement of a Unit:

1. Click the Loopback Test tab. See Fig. 19.

2. Click T est.

3. Click Instantaneous RSSI.

4. Enter some text in the Test String.

5. Enter the desired criteria in other fields in this group. The
default values are recommended for this type of testing.

6. Click Start.

VIEWING DATA IN THE RX AND TX PANES — These
display areas show the data being transmitted and received dur­ing tests. The RX pane shows data being received into the
transceiver. The TX pane shows data being transmitted from
the transceiver. All data sent will be displayed and at times the
pane may become cluttered. You can use the Clear buttons on
the toolbar or the commands in the Edit menu to clear the
panes of data. To clear data in the panes, select Clear RX Pane
or Clear TX Pane.

If the RX pane displays Timeout? each time the Test String

is sent then perform the following tests:

• Vertify that both antennas are properly installed on the
transceivers.

• Reposition the transceivers such that the green signal
strength bar is as long as possible. Normally signal
strengths above .5 are required for reliable communica­tions (see Antenna Selection and Location section).

• Attempt to utilize directional antennas in order to
obtain reliable communications (see Antenna Selection
and Location).

Frequently Asked Questions (FAQs)

Q: Can I use an external antenna?
A: Yes, many di fferent versions of 2.4 GHz omni-directional

or directional antennas can be used. Please cont act Carrier for
additional information.

Q: Can I use other, longer runs of coax than what is provided
from Carrier?

A: Yes. Longer coax can be used but one should keep the
length of the coax as short as possible and use low loss coax as
appropriate for the length of the run.

Q: What types of coax can I use?

A: RG-316, RG-223, LMR240, 300, 400, 600 and many other
types that are suitable for 2.4 GHz RF signals. It i s important to
choose a low loss coax and realize that the longer the coax the
greater the loss. Also, remember that the C arrier transceivers
have a reverse thread SMA female connectors only so your
coax will need to mate with that.

Q: How great a length of coax can I use?
A: It depends on type of coax. A very low loss coax can be

used at distances up to roughly 50 ft. It is critical, however, that
the correct coax and connectors are used and that the coax sys­tem loss is not too great. The maximum power out of a Stand­Alone Carrier Transceiver at the reverse thread SMA connec­tor is 500 mW.

Q: When should I use a directional antenna versus an omni ­directional antenna?

A: A directional antenna is a good choice any time you have
only a specific direction from which signals are sent or
received. If you have a Host (master) Carrier transceiver and
there are Remote Carrier transceivers in all directions from t h e
Host you should use a directional antenna in most if not all
cases. A directional antenna can extend your range by concen­trating the radiated energy from the antenna in a certain dire c­tion. Also, a directional antenna will only rece ive signals that
are in its specific angle reception. RF interference outside the
antennas area will not be ‘visible’ by the antenna and in this
way can increase the transceivers receive capability.

Q: The range specification with omni-directional antennas is
2 miles. Does that require line-of-sight?

A: Yes it does. If the range between antennas is short, say
1000 ft and there are no major obstructions such as earth,
major metallic structures or other obstructions, chances are
good that an acceptable RSSI (receive signal strength i ndica­tion) will be achievable at each transceiver. The problem is,
every applications environment is different and there is no way
to know for sure unless one tests the units in that actual physi­cal setting.

Q: How much does line-of-sight matter with Carrier transceivers?
A: As a general rule, line-of-sight is required to assure commu-

nications. The Carrier transceivers operate at 2.4 to 2.4835
GHz with a maximum power output of 500 mW. The trans­ceiver’s ability to receive adequate signal levels is entirely
dependent on the placement of the ant ennas and the distance
they are from one another. There is no absolute guarantee in
advance that a given installation of Carrier transceivers will
yield a good communication link. However, if the range is
under 1000 ft, adequate communication can be accomplished
in many cases without line-of-sight as long as the proper anten­nas have been selected and installed as required. In general,
with ranges up to and exceeding 1500 ft, line-of-sight is
required.

14

Q: Should I incorporate lightning surge protection for my
transceiver?

A: It is a good idea whenever your coaxial cable lengths are
20 feet or more. Contact your Carrier representative.

Q: What is the highest baud rate of the Carrier RS-485
adapter?

A: 9600 Baud.
Q: How many network IDS are available?
A: 64,000
Q: How can I improve communications indoors?
A: Try using directional antennas to lessen or eliminate bounc-

ing signals being received from the remotes.

Q: Is it possible for CCN communication retries to happen
because of wireless interference?

A: Yes, although Carrier wireless modems are designed to
avoid communication interruption, it is possible for the user to
see duplicate alarms on a ComfortWORKS® or Comfort­VIEW™ display due to wireless interference.

Q: Are there limits to the application of wireless CCN
communications?

A: Ye s. As with any wireless communication, the transceiver
can be interfered with by a physical blockage or electrical
interference. Carrier wireless transceivers should NOT be
installed in applications where temporary loss of communica­tions cannot be tolerated by the control system. Suitable appli­cations include equipment monitoring, alarm monitoring,
control overrides and temporary service connections.
