1.0 RF Engine 26X Series OEM Modules Overview
The RF Engine 26X Series (Model Number RF26X) is an IEEE 802.15.4, low power,
highly-reliable solution to embedded wireless control and monitoring network needs that
require high data rates. The Model RF26X is pin-compatible with Digi International’s
XBee and XBee-PRO RF modules.
The RF26X embeds Synapse’s SNAP OS, the industry’s first Internet-enabled, wireless
mesh network operating system into the Atmel ATmega128RFA1 single-chip AVR®
microcontroller with an integrated transceiver that delivers up to 2Mbits/sec. These low-
cost modules can have a range of up to 4,000 feet and power consumption as low as
0.37 μA to enable a new generation of battery-driven systems.
SNAP’s on-board Python interpreter provides for rapid application development and
over-the-air programming, while Atmel’s low-power RF single-chip design saves board
space and lowers the overall Bill of Materials and power consumption. The RF26X is
approved as an FCC Part 15 unlicensed modular transmitter. The modules provide up
to 16 channels of operation in the ISM 2.4GHz frequency band. The RF26X contains
both a power amplifier for transmission and a low noise amplifier in the receive path for
extended range.

2.0 Agency Certifications
2.1 United States (FCC)
The Model RF26X modules comply with Part 15 of the FCC rules and regulations.
Compliance with the labeling requirements, FCC notices and antenna usage guidelines
is required. In order to comply with FCC Certification requirements, the Original
Equipment Manufacturer (OEM) must fulfill the following requirements.
1. The system integrator must place an exterior label on the outside of the final
product housing the RF26X Modules. Figure 2.1 below shows the contents that
must be included in this label.
2. RF26X Modules may only be used with the antenna that has been tested and
approved for use with the module. Please refer to the antenna table provided in
this section.
2.1.1 OEM Labeling Requirements
NOTICE: The OEM must make sure that FCC labeling requirements are met. This
includes a clearly visible exterior label on the outside of the final product housing that
displays the contents shown in Figure 2.1 below.
RF26X Data Sheet Document Number 430141-01A Page 10 of 14
2.1.2 FCC Notices
WARNING: The RF26X modules have been tested by the FCC for use with other
products without further certification (as per FCC Section 2.1091). Changes or
modifications to this device not expressly approved by Synapse Wireless Inc. could void
the user’s authority to operate the equipment.
NOTICE: OEM’s must certify final end product to comply with unintentional radiators
(FCC Section 15.107 and 15.109) before declaring compliance of their final product to
Part 15 of the FCC Rules.
NOTICE: The RF26X modules have been certified for remote and base radio
applications. If the module will be used for portable applications, the device must
undergo SAR testing.
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.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interferences, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.

2.1.3 FCC Approved Antennas
The RF26X modules are FCC-approved for fixed base station and mobile applications.
The FCC requirement for mobile applications states that the antenna must be mounted
at least 20 cm (8 in) from nearby persons.
Notice: To reduce potential radio interference to other users, the antenna type and its
gain should be chosen so that the equivalent isotropically radiated power (e.i.r.p.) is not
more than that permitted for successful communication. This module has been
designed to operate with the antennas listed below in Table 2.1. The required antenna
impedance is 50 ohms.

RF Exposure WARNING:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20cm between the radiator and your body. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
NOTICE: The preceding statement must be included as a CAUTION statement in OEM
product manuals in order to alert users of FCC RF Exposure compliance.
2.2 Canada (IC)
This device complies with Industry Canada license-exempt RSS standard(s). Operation
is subject to the following two conditions: (1) this device may not cause interference,
and (2) this device must accept any interference, including interference that may cause
undesired operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry
Canada. To reduce potential radio interference to other users, the antenna type and its
gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not
more than that necessary for successful communication.
This radio transmitter Model: RF26X, IC: 7084A-RF26X has been approved by Industry
Canada to operate with the antenna types listed below with the maximum permissible
gain and required antenna impedance for each antenna type indicated. Antenna types
not included in this list, having a gain greater than the maximum gain indicated for that
type, are strictly prohibited for use with this device.
