Preliminary DN-24 - 2.4 GHz RS-232C and RS-232C/RS-485 Serial Modems Series - Optional 128-Bit AES Encryption - Point-to-point,Point-to-multipoint, Peer-to-peer and Store & Forward Capabilities - Frequency Hopping Spread Spectrum Transceiver 2.4 GHz - 250 kbps RF Data Rate - Transmitter Power up to 100 mW EIRP with 2 dBi Antenna Wireless - FCC and Canadian IC Certified for Unlicensed Operation Serial The DN-24 series 2.4 GHz serial modems provide a low cost, ready-to-use solution for robust wireless data communications in the 2.4 GHz ISM band. There are currently two Modems products in the DN-24 series, the DN-24G and the DN-24GI. The DN-24G provides an RS-232C serial interface. The DN-24GI offers a selectable RS-232C or two-wire, multi- drop RS-485 interface. DN-24 series modems are based on Muratas DNT24 frequency hopping spread spectrum (FHSS) transceiver, and can communicate with other DNT24-based modems and sensor nodes, as well as customer developed products. DN-24 series modems are supplied with a dipole antenna and a wall-plug power supply. DN-24 modems transmit data at 250 kbps. Each modems output power can be set up to 100 mW EIRP using the supplied 2 dBi dipole antenna. DN-24 series modems are well-suited for sensor and data networks carrying moderate traffic that need robust communications in locations with non-ideal RF propagation and/or where RF interference or noise are present.
