| The DNT2400 is a low cost, long range, multi-purpose, multi-function 2.4 GHz frequency hopping OEM RF module. It supports both analog and digital I/O and serial data and has the ability to auto-report and sleep between reports, reducing power consumption. The DNT2400 provides a selection of over-the-air data rates and transmit power levels allowing one module to work for many products and giving the designer insurance that the radio performance can be tweaked if needed when the design is finished without having to design in another radio. The DNT2400 supports point-to-point, point-to-multipioint, peer-to-peer, and tree routing networks.
Highly Reliable and Secure FHSS Capabilities at Very Low Cost
- RFM proprietary frequency hopping technology provides robust communications reliability, provides interference rejection and minimizes multipath fading
- 2.4 GHz ISM band allows the DNT2400 to be used license-free world-wide
- AES-128 Encryption allows the most sensitive data to be securely sent wirelessly
- Tree Routing with Fail Over extends coverage area
- Low cost provides substantial cost savings over existing long-range radios without compromising features or radio performance
Highly Configurable Including RF Data Rate and RF Transmit Power
The DNT2400 enables the OEM designer to fit the radio to the application rather than having to fit the
application to the radio. Configuration options include:
- RF Data Rates
- RF Transmit Power
- Frequency Hopping Rate
- Bandwidth Allocation
- Co-Located Network Support
- Sleep Modes
Flexibility of the DNT2400 means that OEM designers no longer have to become familiar with nor stock multiple radio modules

| White Papers |
Lightning and Surge Protection
Because wireless systems are typically located out of doors and have components located on towers and tall buildings, they are especially susceptible to damage from lightning. This paper explores the proper design and implementation of a communications surge protection system to reduce down time and lower liability for people and property. (~ 152 KB, Adobe PDF format.) |
RF Power Options in ZigBee™ Solutions
While ZigBee is a "low power" standard, "high power" product versions are much needed — and are very much ZigBee standard. This paper explains how the the availability of ZigBee radios with high and low RF power options is key to ZigBee's appeal in industrial settings, allowing design engineers to tie radio selection directly to an application’s requirements for range and resistance to multipath fading. |
WaveBolt System Description
The WaveBolt™ system is a fixed wireless point-to-multipoint Internet access system designed specifically for residential and small business customers in areas where DSL and cable modem access are unavailable, unaffordable or otherwise undesirable. The WaveBolt system provides data speeds comparable to ADSL. Simple to install, the WaveBolt CPE in many cases will be installed by the end user. And, where customers choose to have the CPE installed, a single, short site visit is all that is required to complete the installation. (~ 162 KB, Adobe PDF format.) |
Wireless Communications for Industrial Applications
This paper examines the unique requirements and challenges of wireless communications in an industrial setting and provides an overview of RFM wireless products designed specifically for these applications. The information presented serves as a guide for systems integrators and end users responsible for factory floor automation, industrial/PLC control, SCADA, telemetry and related data communications applications. (~ 136 KB, Adobe PDF format.) |
Wireless Transceivers—Make or Buy?
In choosing to add wireless data capability to a new or existing product, every designer faces a critical decision: whether to engineer the functionality in-house or buy a ready-made module for the application. This paper provides a cost analysis to explore the relative merits of each approach. (~ 160 KB, Adobe PDF format) |
ZigBee Wireless Transceiver Engineering Options
ZigBee's mesh networking capability, which compensates for obstructions and reduces range requirements, is especially prized in industrial applications. But with a technology this new, how can the RF designer best realize a successful ZigBee implementation? This white paper provides a brief, realistic assessment of ZigBees value in industrial environments, examines the types of components available today at the chip and module level, and discusses the practical considerations to be weighed in deciding to pursue ZigBee mesh networking in a specific application. |

The DNT2400 Development Kit is available as part number: DNT2400DK
The DNT2400 FHSS transceiver module is a low cost, high-power solution for point-to- I/O point
and point-to-multipoint wireless systems in the 2.4 GHz ISM band. The RF output power of the
DNT2400 can be set from 1 mW to 100 mW, and the RF data rate can be set from 38.4 to 500 kb/s. The
DNT2400 receiver includes a low-noise preamplifier protected by two SAW filters, providing an
excellent combination of receiver sensitivity and out-ofband interference rejection. The DNT2400
module includes analog, digital and serial I/O, providing the flexibility and versatility to serve
applications ranging from cable replacements to sensor networks. The DNT2400 supports point-to-point, point-to-multipioint, peer-to-peer, and tree routing networks. |
