    The ZMN2430 Series 2.4 GHz transceiver modules provide a low cost solution for point-to-point, point-to-multipoint and MESH wireless systems. The ZMN2430 Series provides the flexibility and versatility to serve applications ranging from cable replacements to sensor networks. Based on the IEEE 802.15.4 wireless standard and the ZigBee protocol stack, ZMN2430 Series modules are easy to integrate and provides robust wireless communications including MESH network operation. The ZMN2430 Series also includes RFM’s powerful CSM application profile, which eliminates the need for customer firmware programming.

    ZMN2430 Series modules are shipped loaded with one of three firmware configurations: coordinator ("C"), router ("R") or end node("E"). Each ZigBee network will include one, and only one coordinator. The "C" module coordinates the overall network operation and is the host application or gateway interface point for the network. The "R" modules are capable of retransmitting messages and provide the mesh networking infrastructure in a ZigBee network. The "E" modules provide field connection points for sensors, data loggers, PLCs, etc. The coordinator and the routers in a ZigBee network must stay active (awake) continuously to support network operation. End nodes can be sleep duty cycled where needed for extended battery life operation.

    VERSITILITY. Comprised of the low-power 1mW RF power LPR2430 / LPR2430A and the extended range 100mW RF power LPR2430ER / LPR2430ERA, the RFM LPR2430 Series modules provide the flexibility and versatility to serve a variety of applications, from simple cable replacement to remote terminal data collection to sophisticated sensor networks. The LPR2430 includes CNL V2.0 Network Layer firmware which features a flexible and simple-to-use Application Programming Interface.

    SLEEP CAPABILITY. LPR2430 series modules provide years of battery operation supported through two sleep modes. Timer sleep allows the module to be configured to wake as often as every 100 milliseconds or as infrequently as once every 3.5 years. Interrupt sleep lets the module sleep until it is awoken by either an edge triggered interrupt or an ADC value exceeding configurable limits. Regardless of what wakes the module, the designer can configure the module to remain awake for up to 2 seconds after sending its data to provide an opportunity for an application to communicate to the module before it returns to sleep.

    I/O AND AUTO REPORT CAPABILITY. LPR2430 series modules feature Analog, Digital and Serial I/O including Analog & Digital I/O binding.

  • Standard UART interface for serial communications plus 6 GPIO, 3 ADCs, and 2 DACs (PWMs)
  • With the I/O Binding feature, one node has the ability to output on 2 GPIO lines the input value of 2 GPIO lines from another node
  • Auto-reporting features allow many sensor nodes to be built without a dedicated microcontroller - the micro-controller on the module does all the work
  • Auto-reporting mode provides module I/O updates based on timer or interrupts - without the need for the application to poll or otherwise request data
  • Interrupts are generated by edge-triggered events or by exceeding user-defined limits on ADC values - and any interrupt can be used to wake a sleeping mode and have the module send its I/O data

    OVERCOMES OBSTRUCTIONS / MULTIPATH FADES. LPR2430 modules feature a one-hop relay that enables one node to send data to a base radio through another node. This unique feature alleviates problems caused when a network works well at commissioning but later periodically loses nodes for periods of time. Yet it doesn’t burden the entire network with the complexity and latency of full mesh – the relay is only used when the node cannot communicate directly with the base. Nodes periodically verify their communication paths to the base as well as to other nodes in the network. The application is not even aware this is happening – it is all handled by the modules.

    SAME FORM FACTOR. At 1.05 sq. inch footprint, the LPR2430 series has the same form factor as RFM’s Wi-Fi WSN802G modules, wireless mesh XDM2140 series modules, and ZigBee ZMN2430 series modules.

    SAME PINOUT as RFM’s Wi-Fi WSN802G modules, wireless mesh XDM2140 series modules, and ZigBee ZMN2430 series modules

    FCC / IC / ETSI CERTIFIED. The LPR2430 series modules are certified for unlicensed operation in the USA, Canada and Europe.

    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.

    Developer Kits
    The ZMN2405HPDK Developer’s Kit comprises two high power serial interface boards built around the 100mW ZigBee ZMN2405HP module. The ZMN2405DK allows developers to get up and running quickly using either USB or RS-232 interfaces.

    The self-contained modems have momentary switches, LEDs, thermister, and potentiometer and can operate on standard 9V akaline batteries. This provides a simple, effective way to test the range and operation of the radios in the real-time environment. The onboard I/O can be disconnected, allowing user inputs to be connected to the module inputs using connectors.

    The ZBDemo program included on the supplied CD allows the reading and writing of end device inputs and outputs as well as network discovery and configuration. If your individual wireless requirements could benefit from the application of ZigBee technology, the ZMN2405HPDK is the premier first step. The ZMN2405HPDK should be selected also by those wishing to use the RFM ZMN2430HP module.
