The DNT900 series transceivers provide highly reliable wireless connectivity for point-to-point, point-to-multipoint, peer-to-peer, and tree routing applications.
Frequency hopping spread spectrum (FHSS) technology ensures maximum resistance to multipath fading and robustness in the presence of interfering signals, while operation in the 900 MHz ISM band allows license-free use in the US, Canada, South America, Israel, Australia and New Zealand. The DNT900 supports all standard serial data rates for host communications from 1.2 to 460.8 kb/s through a standard serial port as well as a SPI port configurable as Master or Slave. On-board data buffering and an error-correcting air protocol provide smooth data flow and simplify the task of integration with existing applications. Key DNT900 features include:
Multipath fading resistant frequency hopping technology with up to 50 frequency channels (902 to 928 MHz).
Selectable 1, 10, 100, 250, 500 or 1000 mW transmit power with a firmware interlock of 85 mW maximum for 500 kb/s operation.
Support for point-to-point or point-to-multipoint applications with tree routing for extended coverage.
AES-128 encryption secures data
FCC 15.247 certified for license-free operation.
Separate Serial Port for Diagnostics
40 mile plus range with omni-directional antennas (antenna height dependent).
Dynamic TDMA slot assignment that maximizes throughput and CSMA modes that maximizes network size.
Transparent ARQ protocol with data buffering ensures data integrity
Simple serial interface handles both data and control at up to 460.8 kb/s plus a Master/Slave SPI por
