DNT24 Hardware
The major components of the DNT24 include a
2.4 GHz FHSS transceiver and a low current 8-bit
microcontroller. The DNT24 operates in the 2.4 GHz
ISM band. There are 12 selectable hopping patterns
providing compatibility with frequency allocations in
most regions of the world. The DNT24 also has two
selectable RF output power levels: 10 mW and
63 mW.
The DNT24 provides a variety of hardware interfaces.
There are two serial ports plus one SPI port. Either the
primary serial port or the SPI port can be selected for
data communications. The second serial port is dedi-
cated to diagnostics. The primary and diagnostic serial
ports support most standard baud rates up to
250.0 kbps. The SPI port supports data rates up to
500 kbps. The DNT24 also includes three ADC inputs,
two DAC outputs, and six general-purpose digital I/O
ports. Four of the digital I/O ports support an optional
interrupt-from-sleep mode when configured as inputs.
The radio is available in two mounting configurations.
The DNT24C is designed for solder reflow mounting.

The DNT24P is designed for plug-in connector mount-
ing.
DNT24 Firmware
DNT24 firmware operates using hybrid Ad Hoc TDMA
channel access optimized for periodic burst transmis-
sions. DNT24 firmware operates “out of the box” using
point-to-point transparent serial mode, with point-to-
multipoint, peer-to-peer and store & forward system
topologies also supported.
DNT24 firmware provides the user with a rich set of
configuration options including a choice of hopping
patterns, hopping dwell times, serial and/or SPI data
port operation, serial and SPI data rate selection, RF
output power selection, plus configurable analog and
digital I/O lines.
Data integrity is protected by 24-bit error detection,
with optional ACK and automatic transmission retries
or redundant transmissions. 128-bit AES encryption
provides a high level of data security for sensitive
applications. Sensor networks can take advantage of
timer or event-based data reporting and remote node
sleep cycling for extended battery life.
