module has been designed to allow OEMs to easily add Bluetooth and ANT+ wireless connectivity in their product offering. The GEMDEV2 module incorporates GEMHCI protocol software specifically designed to enable fitness machines such as treadmills, exercise bikes, ellipticals, rowers, stair climbers and step machines to wirelessly communicate exercise data with smart phones, tablets, and leaderboard software systems. The GEMDEV2 module is based on Nordic Semicondutor’s nRF52832 multiprotocol Bluetooth and ANT+ chipset. The GEMDEV2 module offers a USB host interface and has a maximum transmit power of +4dBm, and a sensitivity of -96dBm. This manual is intended to assist hardware integration of the GEMDEV2 module into a given design. Details on Wahoo’s GEMHCI software can be found www.wahoogym.com.

If possible, move mechanical items out and away from a keepout area of 53mm x 20mm from the GEMDEV2 module edge. Antenna Characteristics The GEM 2 module includes an integrated monopole chip antenna. Antenna performance will depend on host PCB layout. The following plots show antenna radiation pattern of the GEM 2 antenna. 2.4GHz Antenna Performance Efficiency 2400MHz 65.72% 2442MHz 62.72% 2484MHz 59.73% 2.442GHz Peak Gain 4.08 dBi 3.95 dBi 4.17dBi 2.484GHz S11 -16.0 dB -14.8 dB -13.3 dB Mechanical Information Dimensions (in mm) Connecting GEMDEV to Console MCU The GEMDEV2 is designed for connection to fitness equipment console MCUs through its USB interface. The GEMDEV2 has a Silcon Labs CP2104 USB to UART Bridge IC allowing the GEM module UART to communicate properly over a USB interface as a virtual communication port (VCP). Drivers are available for Windows, Linux, and Android. https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx GEMDEV2 Host Protocol The GEMDEV2 uses Wahoo’s GEMHCI protocol for communications between the GEMDEV2 board and the console MCU using the USB connection. The GEMHCI protocol is designed to operate through the virtual communications port with a port speed of 115.2Kbps. The GEMHCI protocol is a binary protocol and is used to configure the GEMDEV2 operation as well as pass fitness equipment related data to the GEMDEV2 for broadcasting to connection applications using its Bluetooth/ANT+ radio. Details of the GEMHCI protocol are provided in the GEMHCI reference manual. Please contact Wahoo for the latest version of the GEMHCI reference manual. Regulatory & Standards Information FCC & Industry Canada The GEMDEV2 module has modular approval for the United States and Canada. To ensure compliance when using the GEM 2 module in a design, the OEM is required to adhere to the implementation considerations supplied in this hardware integration guide. Federal Communication Commission (FCC) Radiation Exposure Statement: This device is in compliance with SAR for general population/uncontrolled exposure limits in ANSI/IEEE C95.1-1999 and had been tested in accordance with the measurement methods and procedures specified in OET Bulletin 65 Supplement C. This transceiver must not be co-located or operating in conjunction with any other antenna, transmitter, or external amplifiers. Further testing / evaluation of the end product will be required if the OEM’s device violates any of these requirements. The GEMDEV2 Module is fully approved for mobile and portable applications. FCC Labeling Requirements WARNING: The OEM must ensure that FCC labeling requirements are met. This includes a clearly visible label on the outside of the OEM enclosure specifying the appropriate FCC identifier is visible. Contains FCC ID: PADWF127 IC: 10563A-WF127 If OEM device is larger than 8x10cm, the following FCC part 15.19 statement has to be visible on outside of device: The enclosed 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. Label and text information type should be large enough to be legible and consistent with the dimensions of the equipment and the label. The type size is not required to be larger than eight points. Comments The OEM should have their device tested by a qualified test house to verify compliance with FCC Part 15 Subpart B limits for unintentional radiators. Any modifications to the GEMDEV2 module could void the OEM’s authority to operate the equipment. 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 not cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to correct the interference by one or more of the following measures: • Re-orient or relocate the receiving antenna • Increase the separation between the equipment and the receiver • Connect the equipment to an outlet on a circuit that is different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. FCC Warning: “THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES AND INDUSTRY CANADA LICENSE-EXEMPT RSS STANDARD(S). 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. Industry Canada (IC) Warning: 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. French equivalent: Le présent appareil est conforme aux CNR d'Industrie Canada applicable aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. IC Radiation Exposure Statement This device is in compliance with SAR for general population/uncontrolled exposure limits in IC RSS-102 and had been tested in accordance with the measurement methods and procedures specified in IEEE 1528. REMARQUE IMPORTANTE Déclaration IC d'exposition aux radiations Ce EUT est conforme avec SAR pour la population générale / limites d'exposition non contrôlée à IC RSS-102 et a été testé en conformité avec les méthodes de mesure et procédures spécifiées dans la norme IEEE 1528. Modular Approval OEM is still responsible for testing their product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). Approbation modulaire OEM intégrateur est toujours responsable de tester leur produit final pour les exigences de conformité supplémentaires nécessaires à ce module installé (par exemple, les émissions de périphériques numériques, les exigences de périphériques PC, etc.) IMPORTANT NOTE: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the Canada authorization is no longer considered valid and the IC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate Canadian authorization. NOTE IMPORTANTE: Dans le cas où ces conditions ne peuvent être satisfaites (par exemple pour certaines configurations d'ordinateur portable ou de certaines co-localisation avec un autre émetteur), l'autorisation du Canada n'est plus considéré comme valide et l'ID IC ne peut pas être utilisé sur le produit final. Dans ces circonstances, l'intégrateur OEM sera chargé de réévaluer le produit final (y compris l'émetteur) et l'obtention d'une autorisation distincte au Canada. Le produit final doit être étiqueté dans un endroit visible avec l'inscription suivante: " GEMDEV2 Module Contient des IC: 10563A-WF127" CE The GEMDEV2 Module has been tested against the appropriate regulatory standards for European market. OEMs should consult a qualified test house to ensure their product meets all regulatory requirements. The GEM Module Declaration of Conformities is below. Test reports are available upon request.
