The ZMN2430 2.4 GHz transceiver module is a low cost solution for point-to-point,
point-to-multipoint and MESH wireless systems. The ZMN2430 module 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, the ZMN2430 module is easy to integrate and provides robust wire-
less communications including MESH network operation. The ZMN2430 also in-
cludes RFM’s powerful CSM application profile, which eliminates the need for
customer firmware programming.

ZMN2430 Firmware Configurations
ZMN2430 modules are shipped loaded with one of three firmware configurations: coordinator, router or end
node. Each ZigBee network will include one, and only one coordinator. This module coordinates the overall net-
work operation and is the host application or gateway interface point for the network. The part number designation
for a coordinator is ZMN2430-C. Router modules are capable of retransmitting messages and provide the mesh
networking infrastructure in a ZigBee network. The part number designation for a router is ZMN2430-R. End node
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. The part number designation for an end node is
ZMN2430-E. A router can provide the same field connection support as an end node, but a router cannot be sleep
duty cycled without affecting mesh network operation. Specify the number of modules for each firmware configu-
ration when ordering ZMN2430 modules.
CAUTION: Electrostatic Sensitive Device. Observe precautions when handling.

ZMN2430 Firmware
ZMN2430 Hardware
The major hardware component of the ZMN2430 is
the CC2430 IEEE 802.15.4 compatible transceiver
with integrated 8051 microcontroller. The ZMN2430
The main firmware components in the ZMN2430
include the ZigBee protocol stack and RFM’s CSM
standard module application profile. The ZigBee proto-
col stack implements networking and security, with
underlying support from the 802.15.4 Media Access
Control (MAC) layer. The CSM profile provides an
application programming interface (API) for all the
ZMN2430 application hardware interfaces. The CSM
profile includes Network Discovery, Send/Receive
Serial Data, Read/Write SPI Port, Read ADC Inputs,
Write DAC Outputs, Read/Write GPIO and Module
Configuration services. In addition, the CSM profile
provides two sleep modes - timer sleep and interrupt
sleep. See the ZMN2430 ZigBee Module Developer’s
Kit User’s Manual for complete details of the CSM pro-
file API.
operates in the frequency band of 2405 to 2480 MHz
at a nominal output power of 1 mW.
Two crystals are provided to operate the CC2430, a
32 MHz crystal for normal operation and a 32.768 kHz
crystal for precision sleep mode operation.
The ZMN2430 provides a variety of application hard-
ware interfaces including an SPI interface, UART in-
terface, three 12-bit ADC inputs, two PWM (DAC)
outputs, and six general purpose digital I/O ports.

RFIO Stripline
The RFIO pad on the radio module is connected directly to an antenna on the host circuit board, or to an MMCX
or similar RF connector. It is important that this connection be implemented as a 50 ohm stripline. Referring to
Figure 3, the width of this stripline depends on the thickness of the circuit board between the stripline and the

1.75 times the thickness of the circuit board. Note that other circuit board traces should be spaced away from the
stripline to prevent signal coupling, as shown in Figure 4. The stripline trace should be kept short to minimize its
insertion loss.
