HN-250 HN-250U Features: Benefits: 2.4 GHz Frequency Hopping Spread Exceptional immunity to multipath Spectrum Technology fading and jamming 2.4 GHz 460 kb/s over the air data rate Supports high speed applications 115 kb/s RS232 data rate needing long range Frequency 230 kb/s USB data rate Co-location of multiple networks without Hopping 32 Hopping Patterns interference FCC Certified and CE marked License-free application worldwide Wireless Data Integral 6 dB patch antenna or Cost-effective, simple installation external antenna options Connects to PC Serial or USB ports Modems RS-232 asynchronous or USB serial interface The HopNet 250 family of modems are versatile, low cost, multi-purpose 2.4 GHz frequency-hopping wireless data modems. Built around the RFM WIT2450 radio, the HN-250, HN-250U, HN-254 and HN254U have integral 6 dB patch antennas creatingsingle piec modems. Also built around the WIT2450, the HN250X and HN250UX are equipped with RF connectors instead of patch antennas to allow the use of high gain and/or remote external antennas. Communication with the HN-250, HN250X and HN254 is through a standard RS-232 interface at up to 115.2 kb/s. Communication with the HN-250U, HN250UX and HN-254U is through a 230 kb/s USB interface. All HN series modems communicate over the air at 460 kb/s in both point-to-point and point-to-multipoint networks.
