ODULE
The HAN ZigBee® Module connects to, and is powered by a host device, but
contains its own processor, RF circuitry, and integral antenna. It transmits and
receives digital data, such as device status or consumption. The HAN ZigBee
Module is designed to be a universal solution for adding RF capability to a variety
of Aclara Intelligent End Devices (IEDs).
The Ember EM260 radio IC in the HAN ZigBee Module utilizes the IEEE
802.15.4 physical layer protocol for the 2.4 GHz Industrial, Scientific and Medical
(ISM) radio band. This protocol provides for 16 channels at 5 MHz intervals
within the 2405 MHz to 2480 MHz range. Modulation is accomplished by Offset
Quadrature Phase Shift Keying (OQPSK), and no subcarrier is used.
The HAN ZigBee Module transmits data at a rate of 250 kilobits per second, with
an occupied bandwidth of 2 MHz, and a carrier frequency stability of ± 40 ppm (98
kHz for a 2450 MHz carrier frequency).
A voltage regulator on the HAN ZigBee Module controls the PA IC supply
voltage, and consequently, the transmitter output power. This regulator is
calibrated and set at the time of manufacture.
In accordance with the FCC antenna requirements of section 15.203 and 15.204(c),
the HAN ZigBee Module shall not be used with any antenna aside from the
approved internal antenna installed at the time of production. Likewise, the HAN
ZigBee Module is not to be co-located or used in conjunction with any other
antenna or transmitter.
The HAN ZigBee Module is not intended for, and shall not be used in a handheld
or body worn device. The installation of the HAN ZigBee Module must provide a
minimum of 20 centimeters separation between the module and the body of the
user during normal operating conditions.
The PIC24FJ256 microchip controller controls the transmission or reception mode
and channel selection of the radio. It also serves as the data transfer interface
between the radio chip and the outside device in which the HAN ZigBee module is
installed. The PIC implements the network layer protocol used with the 802.15.4
PHY layer. This network layer may either be the ZigBee protocol or a proprietary
network protocol.

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
2HAN ZigBee™ Module
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 output on a circuit different from that to
which the receiver is connected
consult the dealer or an experienced radio/TV technician for help
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. Changes
not expressly approved by Aclara, could void the user’s authority to operate
the equipment.
This product complies with FCC OET Bulletin 65 radiation exposure limits set
forth for an uncontrolled environment.
The following block diagram summarizes the interfaces and communications
between the system components.
