ZNM Transceiver Modules
Product Description
The RC2400 and RC2400HP RF Transceiver Modules are a series of compact surface-
mounted modules specially designed for the ZNM protocol stack. It can also be used for other
for wireless star and mesh networks based on IEEE 802.15.4 compliant PHY and MAC.
The complete shielded module is only 12.7 x 25.4 x 3.7 mm and comes in both a low current
variant (RC2400) and a High Power version (RC2400HP) with LNA (Low Noise Amplifier) and
PA (Power Amplifier) for extended range. The two variants are pin compatible.

Quick Product Introduction
The RC2400-ZNM/RC2400HP-ZNM are based on the RC2400 series of modules that are
specially designed to comply with IEEE 802.15.4-based industry standards like ZigBee PRO,
6LoWPAN, Wireless HART, ISA100.11a, RC4CE and others.
The ZNM Network Module is designed using the Z-Stack from Texas Instrument which is
ZigBee compliant.
The embedded RF HW and MCU resources in a 100% RF tested and pre-qualified module
shorten the qualification and approval process. No RF design or RF expertise is required to
add powerful wireless networking to the product. The ZNM provides a complete wireless
communication protocol that is interfaced through an API. The API can run over UART or SPI.
Hence, the application protocol is run on an external MCU under full control of the RF module
user.
The RC2400-ZNM/RC2400HP-ZNM can be used to build a complete ZigBee PRO network
module where the entire ZigBee Pro compliant stack and configurable application software is
preloaded in the module and available via API on a serial interface.
About this document
This document is one part of the documentation for the module. It describes the electrical
parameters, RF performance, footprint and PCB layout and regulatory information. Depending
on the selected FW solution one additional User Manual should be used. See
• RC2400/RC2400HP-ZNM User Manual for details on how to use the ZNM module
with preloaded communication stack and API through a serial interface.

Note 1: For detailed pin description, see respective User Manual
Note 2: Pins 17 and 18 are suggested as I2C interface. They can be configured otherwise, but are connected to an
optional internal EEPROM with I2C address = 000. It is recommended to leave these pins as I2C. Sensors and
actuators or any other I2C device can be connected to these pins and accessed from the module.
