www.rfm.com e-mail: info@rfm.com page 3 of 3 ?2008 by rf monolithics, inc. hn-208 - 4/10/08 reliability built around an industrial 802.11b radio, the hn-208 has an integral 6db patch antenna creating a "single piece" modem that is rated over the full -40c to +85c temperature range. communication wit h the hn-208 is through a 10baset ethernet co nnection (hn-208e) or a uart at up to 11 5.2 kbps (hn- 208s). the hn-208i allows monitoring or setting a logic level i nput signal. the hn-208 communicates over the air at up to 11mbp s and supports point-to- multipoint networks. with a nema 4x weatherproof enclosure and aluminum mounting fl ange, the hn-208 is simple to install on the side of a building o r attached to a mast. with no antenna to connect, the hn-208 is simply mounted where t he antenna would ordinarily be mounted. this removes the need f or long antenna cable runs, expensive both in terms of cost and performance. the hn-208 comes with a 50-foot cable that connects to an indoor adapter box (included) that pr ovides a standard 10baset or rs -232 serial connection. the adapter box provides power to the hn-208 through a universal 110/220 50/60 wall-mount power supply (also included). the integral 6db patch antenna provides a line-of-site range of several miles, making the hn-208 ideal for a variety of "last m ile" applications. for applications requiring more antenna gain, the hn-208x replaces the built-in patch antenna with an external tnc connector. low cost when paired with an 802.11b access point, the hn-208 provides a cost-e ffective link from remote devices to ethernet/ip-based ap plications. these applications include intranet-based applications as well as internet access. transmit pow er is +15dbm which allows the hn-208 t o be used worldwide even with the gain of the patch antenna. the hn-208 has been designed specifically to pr ovide wireless lan and internet connectivi ty in industrial, scientific, medical, automotive, and other applications. the hn-208 can be monitored and controlled by a handheld dev ice, by a pc in a central location, or over the inter net. this eliminates cabling and allows the equipment to be moved. additionally, email or te xt messages can be sent out advising appropriate personnel of al arm conditions or status of equipment. the module is an excellent solution for remote sensing and data collection. the hn-208 is both fcc and ce marked. with its operation in the 2.4ghz ism band, the hn-208 can be deployed around the world wi thout a license.
