DNT24MC/MP Hardware
The major components of the DNT24MC/MP include a
2.4 GHz FHSS transceiver and a low current 8-bit
microcontroller. The DNT24MC/MP hops across 15
frequency channels in the 2.4 Ghz ISM band on one of
64 selectable hopping patterns. The DNT24MC/MP
has two selectable RF output power levels: 10 mW
and 63 mW.
The DNT24MC/MP provides a variety of hardware in-
terfaces. 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 dedicated to diagnostics. The primary and diag-
nostic serial ports support most standard baud rates
up to 250.0 kbps. The SPI port supports data rates up
to 500 kbps. The DNT24MC/MP also includes three
ADC inputs, two DAC outputs, and six general-pur-
pose digital I/O ports. Four of the digital I/O ports sup-
port an optional interrupt-from-sleep mode when
configured as inputs. The radio is available in two
mounting configurations. The DNT24MC is designed
for solder reflow mounting. The DNT24MP is designed
for plug-in connector mounting.
DNT24MC/MP Firmware
DNT24MC/MP firmware implements direct peer-to-
peer data transmissions that provide very low trans-
mission latency between all DNT24MC/MP radios in a
network. In addition, efficient point-to-point and point-
to-multipoint networks are readily configured using
direct peer-to-peer transmissions.
DNT24MC/MP firmware provides the user with a rich
set of configuration options including a choice of hop-
ping patterns, 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.
