1. Introduction 1.1. Purpose and Scope The purpose of this document is to provide details regarding the use of the TWIG V 12907 module. It covers all certified off module antenna options, which consist of an on-board PCB antenna, Yagi, and omni antennas. It will inform the designer as to the details required to retain the modular certification for the TWIG V 12907 module. 1.2. Applicable Documents • U.
2. Module and Accessories Part Number Nelson Irrigation Corporation #12907 Description Module with factory firmware. At the factory, the module is assigned a permanent and unique ID after it is integrated into its enclosure. This unique ID also specifies it type as a hub, extender or valve driver. The factory firmware utilizes the unique ID to determine how the module functions within the radio network. At the factory, the module is assigned a permanent antenna assignment (either internal or external).
3. Specifications Network Frequency Range Channels Output Power 902 – 928 MHz 50 (Channel 1 = 902.5 MHz …. Channel 50 = 927.0 MHz) 24 dBm Modulation Type LoRa® i.e. a proprietary spread spectrum modulation scheme that is derivative of Chirp Spread Spectrum modulation External Antenna Connector U.Fl. 50 ohms Internal Antenna Type Dipole, installed in a vertical orientation Nominal Bandwidth 500 KHz Spreading Factor 8 DC Voltage Input Range 1.8 to 5.
4. Approved Antenna Specifications 4.1. PCB Antenna specifications The internal antenna configuration for the module utilizes a PCB dipole that must be placed in a vertical orientation. This dipole has the dimensions shown below: 4.2. External Antenna Connector The external antenna configuration utilizes an on-board a U.FL connector. The outside enclosure must have an RPSMA bulkhead connector. This requirement is accomplished by using a U.

5. EMC Compliance 5.1. Summary The module has been tested and approved as a Modular Radio in accordance with the appropriate FCC and IC standards. The supporting test data may be found in the modular test report. Since this module and its associated set of approved antennas have been certified as a Modular Radio, this allows the end user to integrate this module into an end-product without the requirement of re- certifying the radio module.
5.4. Testing Requirements for End-Product The end-product must be tested and follow the verification process for in accordance to the FCC and IC guidelines. The module needs to be powered and placed in the receive mode for this test. 5.5. Agency Certifications FCC-ID: ZH6-TWIGV IC ID: 9686A-TWIGV The information in this document is subject to change without notice (Rev.
5.6. Agency Statements Federal Communication Commission Interference Statement 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.
Industry Canada Statements 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. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence.
5.7. OEM Labeling Requirements For End-Product The module is labeled with its own FCC ID and IC Certification Number. The FCC ID and IC certification numbers are not visible when the module is installed inside an enclosure, as such the end device into which the module is installed must display a label referring to the enclosed module.
