HN-211R Datasheet, PDF (3/3 Pages) Murata Manufacturing Co., Ltd. – 2.4 GHz Frequency Hopping Wireless Data Modem

Versitility
The HopNet 211 family of modems are a versatile, low cost, multi-purpose 2.4 GHz frequency-hopping wireless data modem. Built around the WIT2411
radio, the HN-211 has an integral 6dB patch antenna creating a "single piece" modem. Communication with the HN-211 is through an asynchronous,
115.2Kbps serial port supporting a standard RS-232 interface or a 921.6Kbps USB version is also available. The HN-211 communicates over the air at
1.23Mbps in both point-to-point and point-to-multipoint networks.
Simplicity
With a NEMA 4X weatherproof enclosure and aluminum mounting flange, the HN-211 is simple to install on the side of a building or attached to a mast.
With no antenna to connect, the HN-211 is simply mounted where the antenna would ordinarily be mounted. This removes the need for long antenna cable
runs, expensive both in terms of cost and performance.
Useability
The HN-211 comes with a 50-foot cable that connects to an indoor Serial Adapter Box (included) that provides a standard RS-232 serial 9-pin D connection.
The HN-214 comes with just a 4-foot cable when long cable runs are not needed. The Serial Adapter Box also provides power to the HN-211 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-211 ideal for a variety of "last mile" applications. For applications requiring more antenna gain, the HN-211X replaces the built-in patch antenna
with an external TNC connector.
When paired with the RFM SNAP2411 family of products, the HN-211 provides a cost-effective link from remote devices to Ethernet/IP-based applications.
These applications include Intranet-based applications as well as Internet access. The HN-211 also is ideal for use in SCADA applications as remote
modems in multipoint configurations and is an extremely cost-effective solution for point-to-point installations. Selectable transmit power levels of 8mW and
65mW allow the HN-211 to be used worldwide even with the gain of the patch antenna.
Based on the third generation RFM WIT2411 spread spectrum frequency-hopping radio, the HN-211 has exceptional multipath fade rejection as well as
immunity to jamming. The WIT2411 is a field proven performer that delivers robust, reliable real-world performance.
The HN-211 is both FCC and CE marked. Combined with its operation in the 2.4GHz ISM band, the HN-211 can be deployed around the world without a
license.
