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 transceivers 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 second. 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 available to transmit. The initiating transceiver is
termed the master and the receiving transceiver 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.
GENERAL
Transmit Power Control — Wireless devices in close
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 plugged
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 the 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-interface
mobility.
The wireless transceivers operate in point-to-point pairs and
broadcast networks.
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 between
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
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 to establish
reliable communications. Directional antennas can be purchased directly from the antenna vendors described in the antenna selection and location section of this manual.
Fig. 1 — Loopback Configuration
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 sent.
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 signal 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).
Site Evaluation Testing — Loopback Test — In
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
Test String.
8. The TX pane should start displaying the Test String at
regular intervals. If the string is being 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 configured 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.
INSTALLATION
Hardware Installation — Prior to installing the transceiver(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 connected 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 corresponding 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 is a reverse thread 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.

b. Locations directly adjacent to walls or other
structures should be avoided for omni-directional
antennas.
c. Barriers between antennas should always be considered (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 determine if bouncing the wireless signal can be utilized
in order to achieve wireless communications.
h. For best results it is recommended that a directional antenna be used in conjunction with an
omni-directional antenna. With this setup signal
strength is improved while antenna lineup is fairly
straightforward.
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 Table 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

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.
The Carrier transceivers support the Broadcast Network
topology. Each transceiver can be configured via its Configuration 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.
Installation onto a CCN Bus — Use the RS-232 to
Networks — Wireless data connectivity applications
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 to install, commission,
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 the transceiver is located
on a rooftop, it is possible to gain wireless access 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 in 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.
TYPICAL SET UP (QUICK START)

change the unit Serial Settings.
Power Management — Power management features
are preset for the Carrier CCN application and do not need to
be altered. See Fig. 14 to view power modes.
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 Table 4.
All transceivers are shipped with OEM access. It is up to the
administrator to assign user privileges from that point on.
PASSWORDS — 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 “oem” as the password. It is recommended for security reasons 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.

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. To 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 data 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.

Using Hop Tables — 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 Tables in
your transceiver (this number may vary for international 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.
10
Session Holdoff — (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.
Table 5 — ID Types
ID TYPE
Vendor ID
EXPLANATION
Assigned at the factory and burned into the
firmware. This number is not modifiable.
This ensures that no other Carrier customer can intercept data assigned to the
ID. There are 64,000 unique Vendor IDs.
A number that identifies the network and
Network ID
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
to 64,000 unique numbers. Units with different IDs cannot communicate with each
other.
For broadcast network communication, the
Source Unit ID
source ID = 0 for the host and the source
IDs for the remotes are 1.
Destination Unit ID The numeric ID of the unit that the transceiver being configured will communicate
with. For a Broadcast network, the host will
have a destination ID =1. The remotes will
each have a destination ID = 0 (the host ID
number)
Alias Source Name A descriptive name for the unit.
Alias Network Name A descriptive name for the network.
Fig. 16 — Quick Configuration Window
Unit Testing — You can test 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.
To 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 provides 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 You 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 Configuration Manager loaded.
Signal Analysis — There are a number of features which
can help you analyze the strength and consistency of your data
signal. They are available via the Advanced Settings tab. See

Test Communications Between Units:
1. Open the Configuration Manager. See Fig. 17.
2. Click the Terminal Mode tab.
3. In Test 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 relative to another based on received signal strength. This test is
only used for stand-alone models.
What You 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 addition, both units must 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 of 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 set up.
Test Communications Between Units:
1. Open the Configuration Program. See Fig. 18.
2. Click the Loopback Test tab.
3. In Test String, enter some text.
4. Enter the desired criteria in other fields in this group. The
default values are recommended for this type of testing.
The minimum for Repeat Every field is 100 msec.
5. Click Start.

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).

System Configuration — Refer to the following to
A: RG-316, RG-223, LMR240, 300, 400, 600 and many other
types that are suitable for 2.4 GHz RF signals. It is important to
choose a low loss coax and realize that the longer the coax the
greater the loss. Also, remember that the Carrier 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 omnidirectional 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 the
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 direction. Also, a directional antenna will only receive 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 indication) 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 communications. 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 antennas 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.
check system configuration:
• Do the power and link LEDs blink 3 times as described
in the Setup section?
• Does the power indicator remain on after power up?
• Are the RS232 9-pin cables or RS485 converters
attached?
• If the RS232 9-pin cable is being used, do all 9 wires in
the serial cable have continuity from one end to the
other?
• Are all connections secure to unit and connected device?
• Does the TX LED blink when you are sending data to
the transceiver from the computer or originating device?
• Does the unit communicate with a loopback test?
• If the transceiver is a Broadcast/Remote or Point-toPoint, are the sync and power LED's on?
• How far apart are the transceivers?
• Are they out of range?
• What antennas are you using?
• Where are they mounted?
• If there is a cable run between the transceiver and the
antenna, how long?
• Have you tried to communicate with the transceiver in
different locations or with different antennas?
• What are the RF barriers between the antennas? See
Table 8.

Frequently Asked Questions (FAQs)
Q: Can I use an external antenna?
A: Yes, many different versions of 2.4 GHz omni-directional
or directional antennas can be used. Please contact 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?
14
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: Yes. 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.
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 bouncing signals being received from the remotes.
