Cirronet Unveils Line of Four Wireless I/O Modems; 900 MHz and 2.4 GHz Devices Offer Choice of Relay and Analog/Digital Wireless I/O.NEW ORLEANS New Orleans (ôr`lēənz –lənz, ôrlēnz`), city (2006 pop. 187,525), coextensive with Orleans parish, SE La., between the Mississippi River and Lake Pontchartrain, 107 mi (172 km) by water from the river mouth; founded -- Cirronet(TM) Inc., a leading provider of wireless industrial and OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and products, introduced a line of four HopNet wireless I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output modems today at the ENTELEC ENTELEC Energy Telecommunications and Electrical Association Conference in New Orleans. The product line includes the HNIO-091R and HNIO-241R relay modems, which operate at 900 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. and 2.4 GHz respectively, and the 900 MHz NHIO-091A and 2.4 GHz HNIO-241A analog/digital modems. Cirronet's new wireless I/O modems feature bidirectional The ability to move, transfer or transmit in both directions. transmission and employ the company's patented frequency hopping spread spectrum (FHSS (Frequency Hopping Spread Spectrum) See spread spectrum. ) technology, known for its superior ability to deliver critical data regardless of environment or conditions. Systems integrators can choose the I/O modem best suited to their applications, with the assurance of thoroughly secure and reliable communications - even when little intelligence resides on either end of the link. The relay modems provide four 250VAC (Volts Alternating Current) See volt and AC. 5A relays, and the analog/digital modems provide two 4-20mA receivers and transmitters along with two digital I/O channels. "The term 'wireless I/O' covers a broad range of applications, and even the simplest can be absolutely mission-critical," said Tim Cutler, Cirronet's vice president of marketing and OEM/industrial sales. "At a water supply pumping station, for example, the signal that controls the front gate can be just as important as the signal that relays a process alarm. In all cases, we offer the most meaningful replacement for a cable, with no compromise in certainty." Unlike wireless data transceivers, for which Cirronet is also well-known, wireless I/O modems transmit voltage or digital signals rather than serial data streams. Analog/digital models are typically used to relay key levels of sensor data, while relay units control the state of such equipment as light fixtures, alarms and locks. Line of sight range extends beyond 20 miles for the 900 MHz I/O modems and up to seven miles for the 2.4 GHz units, depending upon the antenna used. The modems can operate over an input voltage range of +9Vdc to +30Vdc, making them suitable for battery and solar power sources. Class I Div 2 certification allows the modems to be deployed in hazardous locations. All are DIN-rail mountable. Evaluation units of all four Cirronet wireless I/O modems are available immediately, with products slated for general availability in Q2 2005. Pricing will range from $795 for internal radio models to $895 for external radio models. About Cirronet Atlanta-based Cirronet has over 15 years of success in developing innovative wireless data networking and communications products for industrial, OEM and Internet access markets. Employing proprietary frequency hopping spread spectrum (FHSS) radio transmission technology, the company's products offer reliable, long-range performance and unparalleled immunity against jamming and interference. Cirronet products, which are FCC (1) (Federal Communications Commission, Washington, DC, www.fcc.gov) The U.S. government agency that regulates interstate and international communications including wire, cable, radio, TV and satellite.
