Wireless Data
Modem
The HN-250 is a versatile, low cost, multi-purpose 2.4 GHz frequency-hopping wireless data modem. Built
around the WIT2450 radio, the HN-250 has an integral 6dB patch antenna creating a “single piece” modem.
Communication with the HN-250 is through a 921.6kbps (USB version only) or 115.2Kbps (USB or RS-232
versions) asynchronous serial port supporting a standard RS-232 interface. The HN-250 communicates over
the air at 1.23Mbps and supports both point-to-point and point-to-multipoint networks.

HN-250 - 3/14/08
Versatility
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. 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 Cirronet
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.
Useability
Based on the third generation Cirronet 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.
