Modem Module 100Kbps Data

The DN-90 series 900 MHz serial modems provide a low cost, ready-to-use solution for robust wireless data communications in the 900 MHz ISM band. There are currently two products in the DN-90 series, the DN-90G and the DN-90GI. The DN-90G provides an RS-232C serial interface. The DN-90GI offers a selectable RS-232C or two-wire, multi-drop RS-485 interface. DN-90 series modems are based on RFM’s DNT90 frequency hopping spread spectrum (FHSS) transceiver, and can communicate with other DNT90-based modems and sensor nodes, as well as customer developed products. DN-90 series modems are supplied with a dipole antenna and a wall-plug power supply. DN-90 modems transmit data at 100 kbps. Each modem’s output power can be set up to 158 mW EIRP using the supplied 2 dBi dipole antenna. DN-90 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.
