Modems
The HN-208 is a versatile, low cost, multi-purpose 802.11b wireless data modem. Available in three different
versions, the HN-208 series provides an Ethernet connection, an RS-232 serial connection, or a single I/O
connection. The HN-208 communicates with existing 802.11b access points and supports peer-to-peer links
as well.

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 -40°C to
+85°C temperature range. Communication with the HN-208 is through a 10BaseT Ethernet connection (HN-208E) or a UART at up to 115.2 Kbps (HN-
208S). The HN-208I allows monitoring or setting a logic level input signal. The HN-208 communicates over the air at up to 11Mbps and supports point-to-
multipoint networks.
With a NEMA 4X weatherproof enclosure and aluminum mounting flange, the HN-208 is simple to install on the side of a building or attached to a mast.
With no antenna to connect, the HN-208 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-208 comes with a 50-foot cable that connects to an indoor adapter box (included) that provides 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 mile" 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-effective link from remote devices to Ethernet/IP-based applications. These
applications include Intranet-based applications as well as Internet access. Transmit power is +15dBm which allows the HN-208 to be used worldwide even
with the gain of the patch antenna.
The HN-208 has been designed specifically to provide wireless LAN and Internet connectivity in industrial, scientific, medical, automotive, and other
applications. The HN-208 can be monitored and controlled by a handheld device, by a PC in a central location, or over the Internet. This eliminates cabling
and allows the equipment to be moved. Additionally, email or text messages can be sent out advising appropriate personnel of alarm 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 without a license.
