FCC User Information
“NOTE: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.”
Warning: Changes or modifications to this device not expressly approved by Cirronet Inc.
could void the user’s authority to operate the equipment.
RF Exposure
In accordance with FCC requirements of human exposure to radiofrequency fields, the radiating
element shall be installed such that a minimum separation distance of 20cm
shall be maintained from the user and/or general population.
Industry Canada
This Class B digital apparatus meets all requirements of the Canadian Interference
Causing Equipment Regulations. Operation is subject to the following two conditions: (1)
this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
Cet appareillage numérique de la classe B répond à toutes les exigences de
l'interférence canadienne causant des règlements d'équipement. L'opération est sujette
aux deux conditions suivantes: (1) ce dispositif peut ne pas causer l'interférence nocive,
et (2) ce dispositif doit accepter n'importe quelle interférence reçue, y compris
l'interférence qui peut causer l'opération peu désirée.

Theory of Operation
The Cirronet ZMN2400 Series radio modules utilizes the IEEE 802.15.4 standard ZigBee Physical layer
hardware for wireless low data rate monitoring and control applications. The application of the ZMN2400
Series in a wireless network for data collection in industrial monitoring and control.
Block Diagram in Figure 1
The ZMN2400 Series radio modules consist of an RF transceiver and a microprocessor.
The RF transceiver receives data and commands from the microprocessor as well as the clock required by
the RF transceiver.
The Block diagrams in Figure 1 shows both the ZMN2400 (Low Power) and the ZMN2400HP (High Power).
They are the same with the exception of T/R switches and a PA (Power Amp) and a LNA (Low Noise Amp) in
the high power version. The output power is +16 dBm for the high power and 0 dBm for the low power
ZigBee Transceivers.

ZMN2400 Frequency Selection
The ZMN2400 is not frequency agile during run-time, but it can select an unoccupied portion of the spectrum
at startup.
The ZMN-2400 series uses a set of channels as defined by the IEEE 802.15.4 / ZigBee standards which
span a range from 2405 to 2480 MHz with 5 MHz spacing between channels:
Center Frequency (MHz)
2405
2410
2415
2420
2425 (default)
2430
2435

The channel mask is the name used to describe the list of frequency channels that a ZMN-2400 can use.
The default channel mask for client radios allows them to operate on any frequency from 2405 to 2475
(channel 2480 is reserved for manufacturing test purposes and therefore not included).
