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...
