The ZMN2405HPA 2.4 GHz transceiver module is a low cost, high-power solution for
point-to-point, point-to-multipoint and MESH wireless systems. The ZMN2405HPA
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 ZMN2405HPA module is easy to integrate, re-
quires no external antenna, and provides robust wireless communications including
MESH network operation. The ZMN2405HPA includes RFM’s powerful CSM appli-
cation profile, which eliminates the need for customer firmware programming.

ZMN2405HPA Firmware Configurations
ZMN2405HPA 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 ZMN2405HPA-C. Router modules are capable of retransmitting messages and provide the
mesh networking infrastructure in a ZigBee network. The part number for a router is ZMN2405HPA-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
ZMN2405HPA-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
configuration when ordering ZMN2405HPA modules.

ZMN2405HPA Electrical Characteristics
CAUTION: Electrostatic Sensitive Device. Observe precautions when handling.
ZMN2405HPA Hardware
The major hardware component of the ZMN2405HPA is
the CC2430 IEEE 802.15.4 compatible transceiver with
integrated 8051 microcontroller. The ZMN2405HPA
operates in the frequency band of 2405 to 2475 MHz at
a nominal output power of 40 mW.
The ZMN2405HPA 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 ZMN2405HPA provides a variety of application
hardware interfaces including an SPI interface, UART
interface, three 12-bit ADC inputs, two PWM (DAC) out-
puts, and six general purpose digital I/O ports.
ZMN2405HPA Firmware
The main firmware components in the ZMN2405HPA
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
ZMN2405HPA 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 pro-
vides two sleep modes - timer sleep and interrupt
sleep. See the ZMN2405HP ZigBee Module Devel-
oper’s Kit User’s Manual for complete details of the
CSM profile API.
