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 transceiv- ers use Frequency Hopping Spread Spectrum (FHSS) technol- ogy to ensure secure, reliable long-range data transmissions. Frequency Hopping Spread Spectrum technology was devel- oped by the U.S. military to prevent interference or intercep- tion 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 re- tain 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 com- plete 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

The Carrier wireless transceivers enable connection to the Carrier Comfort Network (CCN) in areas where standard wir- ing 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.

Transmit Power Control — Wireless devices in close proximity often experience desensing or overloading. Carrier Wireless Transceivers minimize this problem by providing ad- justments 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 indepen- dent 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.
