Cirronet(TM) Introduces Versatile, Low-cost Wireless Serial Modem; ZN-241G Wireless Modem Leverages 802.15.4 Technology for Cost-Effective Versatility.DULUTH, Ga. -- Cirronet announced today the availability of its ZN-241G wireless modem A modem and antenna that transmits and receives over the air. Wireless modems support several technologies, including 802.11, Bluetooth, CDPD, DataTAC, Mobitex and Ricochet. There are wireless modems for laptops, handhelds and cellphones. , which is built on cost-effective 802.15.4 technology. This versatile device can provide an auto-configured, wireless replacement for RS-232 cable in office environments, and can also serve as a platform for multi-drop RS-485 networks in industrial settings. Housed in an attractive metal enclosure, the ZN-241G is an excellent alternative to hard wiring in commercial environments where wired connections are challenging or impractical. Industry estimates place the minimum cost of wiring materials and installation labor at $10 to $40 per foot, which can quickly soar if the effort encounters obstacles or the cable must be hidden. With a suggested retail price of $129 ($249 for a starter kit of two units), a ZN-241G wireless link costs less than even the simplest wired connection exceeding 25 feet, and allows devices to be moved where needed without recurring wiring costs. "Cirronet's reputation is built on radios that solve complex problems or must deliver data in extremely harsh environments," says Tim Cutler, Cirronet's vice president of marketing. "With the ZN-241G, we're applying our expertise to applications that require low-cost but reliable wireless links, with no wireless expertise needed to get up and running. At the same time, the device can provide sophisticated wireless networking See wireless network. for applications that demand it." For point-to-point communications, ZN-241Gs configure the link automatically; all that's required is plugging the devices into two serial interfaces and turning on power. Point-to-multipoint links are set up by simple configuration using an included, intuitive configuration utility, and a repeater function allows a remote node A terminal or computer located apart from the main network. It may refer to a branch office or a traveling user with a laptop. Access to the company LAN is typically made via an Internet or dial-up connection. See remote control software. to relay data through another remote node when the direct path is blocked. The ZN-241G offers RS-232, USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. , and RS-485 interface options, and operates license-free worldwide at 2.4 GHz with over-the-air data rates of up to 250 Kbps.
