The ZMN2430HP 2.4 GHz transceiver module is a low cost, high-power solution for
point-to-point, point-to-multipoint and MESH wireless systems. The ZMN2430HP
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 ZMN2430HP module is easy to integrate and pro-
vides robust wireless communications including MESH network operation. The
ZMN2430HP also includes RFM’s powerful CSM application profile, which eliminates
the need for customer firmware programming.

ZMN2430HP Firmware Configurations
ZMN2430HP 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
ZMN2430HP-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
ZMN2430HP-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
ZMN2430HP-E.
A router can provide the same field connection support as an end node, but a router can-
not be sleep duty cycled without affecting mesh network operation. Specify the number of modules for each firm-
ware configuration when ordering ZMN2430HP modules.
CAUTION: Electrostatic Sensitive Device. Observe precautions when handling.

ZMN2430HP Hardware
The major hardware component of the ZMN2430HP is
the CC2430 IEEE 802.15.4 compatible transceiver
with integrated 8051 microcontroller. The ZMN2430HP
operates in the frequency band of 2405 to 2475 MHz
at a nominal output power of 63 mW.
The ZMN2430HP includes a low noise preamplifier in
the receiver path and a power amplifier in the transmit-
ter path, greatly increasing the operating range of the
CC2430. 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 ZMN2430HP provides a variety of application
hardware interfaces including an SPI interface, UART
interface, three 12-bit ADC inputs, two PWM (DAC)
outputs, and six general purpose digital I/O ports.
ZMN2430HP Firmware
The main firmware components in the ZMN2430HP
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
ZMN2430HP application hardware interfaces. The
CSM profile includes Network Discovery, Send/Re-
ceive 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
ZMN2430HP ZigBee Module
Developer’s Kit User’s Manual
for complete details of
the CSM profile API.

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

groundplane. For FR-4 type circuit board materials (dielectric constant of 4.7), the width of the stripline is equal to
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.
