June 10, 2008 - RF Monolithics releases DNT2400, a long-range frequency hopping spread spectrum (FHSS) modules for original equipment manufacturers (OEMs). Operating in the 2.4 GHz ISM band, the DNT2400 is a multi-purpose, multi-function OEM RF module suitable for wide variety of applications including Supervisory Control And Data Acquisition (SCADA) applications, Industrial Automation and Control, and Wireless Sensor Networking.
The RFM advanced networking features and robust proprietary frequency hopping technology found in the DNT2400 provides an extremely reliable radio with sophisticated features at a remarkably low single piece price of $69.Over-the-air data rates vary from 38.4 to 500 kbps while the transmit power can be adjusted from 1mW to 100mW. Additionally, the DNT2400 provides total flexibility in how fast the radio hops, how bandwidth is allocated between remotes and the base, support for co-located networks, and a variety of sleep modes, to name but a few of the configuration options available. When designers have multiple products needing different radio performance, they can use the DNT2400 for all their products by simply configuring the DNT2400 for the desired performance.
The DNT2400 is pin-for-pin compatible with RFM’s DNT900 giving designers the option of 2.4GHz or 900MHz operation in a single design.The DNT2400 provides a TDMA mode for guaranteed bandwidth as well as a CSMA mode that supports networks of unlimited numbers of nodes. RFM’s advanced networking features and robust frequency hopping technology along with a full 24-bit CRC and ARQ error detection and correction scheme provide an extremely reliable radio with sophisticated features. For WSN applications, the DNT2400 provides the ability to collect sensor data directly from devices using its analog and digital I/O to wirelessly transmit sensor data.
With both a standard UART serial port as well as a collection of 3 ADC inputs, 2 DAC outputs and 6 GPIOs, the DNT2400 is well suited for any sensor application. The DNT2400 is also suitable for battery operation with its ability to auto-report sensor data and to sleep in between reports. RFM offers a developer kit - the DNT2400DK - to help design engineers fast track their designs. The DNT2400DK developer kit will be available in early July from RFM distributors Avnet, Digi-Key, Mouser Electronics, and Nu Horizons.
