| Cirronet Introduces Wireless Serial Modem Cirronet has announced the availability of its ZN-241G wireless modem, which is built on 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 alternative to hard wiring in commercial environments where wired connections are challenging or impractical. 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 to relay data through another remote node when the direct path is blocked. The ZN-241G offers RS-232, USB, 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. write your comments about the article :: © 2006 Networking News :: home page |
