DESIGNING ARIA X2 INTO END APPLICATION

The Aria X2 was designed to be implemented using a carrier board (XW-CB1) that fits a Synapse RF220UF1 socket.

PROGRAMMING

The Aria X2 can be programmed using a JTAG interface or over the air via BLE.

PROGRAMMING VIA JTAG

The process for reprogramming the wireless modules includes a Silabs development board with the necessary debug wires broken out (3.3V, GND, SWDIO, SWCLK). The wireless module’s carrier board (XW-CB1) fits the Synapse RF220UF1’s socket, so a breakout board from Synapse (500202.01A) is used to easily access the pins, as well as provide a reset button.
Simplicity Commander from Silicon Labs is used to flash the firmware onto the module.

1. Open up Simplicity Commander and connect the Silabs dev board to your PC’s USB port. The board should be automatically discovered by the Commander.
2. Switch to the Flash tab.
3. Browse for the .s37 file to load onto the device.
4. Click Flash to program the device.

PROGRAMMING VIA BLUETOOTH OTA DFU

1. The Aria X2 is capable of securely updating firmware via Over-The-Air Device Firmware Upgrade (OTA DFU), using signed and encrypted upgrade files in a custom GBL (Gecko Bootloader) format.
2. Before upgrading via OTA DFU, the encryption key and public key tokens must be flashed onto the device using Simplicity Commander.

CLEANING

The use of “No Clean” paste is recommended as it does not require a wash phase after reflow. Washing a final assembly that uses the Aria X2 is not recommended as water may be captured under the module and/or RF shield causing part degradation.

PACKAGING

The Aria X2 and the accompanying XW-CB1 carrier board each come in sheets of 20pcs

REGULATOR TESTING AND CONFIGURATION

If necessary, the Aria X2 module can be configured for host product evaluation for different operational conditions. In other words, if Aria X2 is implemented into a host system that needs secondary certifications the Aria X2 can be loaded with test firmware to put the radio into different constant transmission or reception states to verify the end device does not emit spurious emissions caused by the Aria X2.

REGULATORY STATEMENTS

FCC Statements
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 interference, and
2. This device must accept any interference received, including interference that may cause undesired operation.

Note : This product 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 product 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 product 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 unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance.

FCC Modular Usage Statement

• Note 1 : This module certified complies with RF exposure requirements under mobile or fixed condition; this module is to be installed only in mobile or fixed applications.
  A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. Transmitting devices designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated with a personal computer, are considered to be mobile devices if they meet the 20 centimeter separation requirement.
  A fixed device is defined as a device is physically secured at one location and is not able to be easily moved to another location.

• Note 2 : Host product manufacturers must provide in their user manual the required RF exposure information for mobile & fixed usage of this module. Host product manufacturers must use the following RF exposure statement in their user manual “This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 cm between the radiator and all persons. This transmitter must not be co-location or operating in conjunction with any other antenna or transmitter.”

• Note 3 : Any modifications made to the module will void the Grant of Certification, this module is limited to OEM installation only and must not be sold to end-users, end-user shall have no manual instructions to remove or install the device, only software or operating procedure shall be placed in the end-user operating manual of final products.

• Note 4 : Additional testing and certification may be necessary when multiple modules are used.

• Note 5 : The module may be operated only with the stubby antenna with which it is authorized.

• Note 6: To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Supplier’s Declaration of Conformity procedure without a transmitter-certified module and a module is added, the host manufacturer is responsible for ensuring that after the module is installed and operational the host continues to be compliant with the part 15B unintentional radiator requirements. Since this may depend on the details of how the module is integrated with the host, the manufacturer shall provide guidance to the host manufacturer for compliance with the part 15B requirements.

• Note 7: The FCC ID label on the final system must be labeled with “Contains FCC ID: 2AVDP-ARI002”

• Note 8 : The FCC rule/s for this module are CFR 47 Part 15 Subpart C.

• Note 9: This modular transmitter is only FCC authorized for the specific rule parts listed on its grant. The host product manufacturer is responsible to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product will require Part 15 Subpart B compliance when the modular transmitter is installed.

ISED Statements
This device complies with Innovation, Science and Economic Development Canada’s 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 and interference, including interference that may cause undesired operation of the device.

Under Innovation, Science and Economic Development Canada’s regulations, this radio transmitter may only operate using the integral antenna under which it was approved

ISED RF Exposure Statement
This equipment complies with ISED radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter

ISED Modular Usage Statement
