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 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.

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.

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 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.

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.

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).

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.

Serial Communications — 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 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

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 Configuration 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 — Several factors effect signal strength:

1.Location

a. Line of sight between antennas is always preferred.

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.

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 and the positive (wire with white line) to screw terminal Pin 6. See Fig 2.

If a transceiver is used to connect directly to a computer, 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 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.

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.
