In the application scenarios of data transmission of film and video, the application scenarios of wireless data and video data transmission of UAV industry will be explained below, The application modes of the airborne terminal and remote control terminal are respectively summarized below, but not limited to the following application modes. 8.1 Airborne Side 8.1.1 With chip ITE6602 Fig 8.1 ARLink-C201-D 8.1.1 Collocate with chip ITE6602 The above application mode is the application scenario of the airborne terminal. The H.264 encoder built-in in C201-D is used. The maximum output resolution of the camera supported by this application mode is 1080P@30, and the interlace input is not supported Due to the general camera HDMI output delay in about 100ms (different types of camera output delay is different), so the delay performance index is medium, but due to ITE66021 cost-effective, so the cost advantage. 8.1.2 With conntek CH7038 Fig 8.2 ARlink-C201-D 8.1.2 with conntek CH7038 The above application mode is the application scenario of the airborne terminal. The H.264 encoder built-in in C201-D is used. The maximum output resolution of the camera supported by this application mode is 1080P@60, and the interlace input is not supported Since the delay of HDMI output of general cameras is around 100ms (different types of cameras have different output delays), the delay performance is medium. However, since some onboard devices only support 1080P60 or 1080P50 output, this solution can solve the compatibility problem of the output of such cameras. 8.1.3 With Perceptive Sensor Module Fig 8.3 ARlink-C201-D With Perceptive Sensor Module The above application mode is the application scenario of the airborne terminal. The H.264 encoder built-in in C201-D is used. The maximum output resolution of the camera module supported by this application mode is 1080P@30. 8.1.4 With embedded Linux platform Fig 8.4 ARlink-C201-D with embedded Linux platform The above application mode is the application scenario of the airborne terminal. The encoding is carried out by the coding chip of the Linux operating system and sent to C201-D through USB0. The USB interface driver of C201-D needs to be installed on the Linux platform and c201-D is only used for transparent transmission of video or data without H.264 encoding. 8.2 Controller Side 8.2.1 C201-D USB0 Fig 8.5 ARlink-C201-D 8.1.4 with embedded Linux platform This application mode is based on the application scenario of ground remote control. External MCU is used to collect the data of rocker and button. When the number of external interfaces of C201-D meets the requirements of remote control, C201-D can also be used as the master MCU, and the SDK of C201-D can be used to realize the control of the buzzer by the rocker acquisition button to collect electricity and detect the buzzer C201-d USB0 is initialized to Device mode by default. Therefore, the USB of an external pad or phone needs to be initialized to Host mode. This solution does not support iPhone/iPad connections. ARLink-C201-D Product Instruction 8.2.2 C201-D USB1 Fig 8.5 ARlink-C201-D with embedded Linux platform This application mode is based on the application scenario of ground remote control. External MCU is used to collect the data of rocker and button. When the number of external interfaces of C201-D meets the requirements of remote control, C201-D can also be used as the master MCU, and the SDK of C201-D can be used to realize the control of the buzzer by the rocker acquisition button to collect electricity and detect the buzzer USB1 of C201-D is initialized to Host mode by default, so USB of external pad or phone needs to be initialized to Device mode. Of course, USB1 can be used as OTG mode through modification of C201-D application layer Generally, mobile phones or pads only have one USB port, so this solution can meet the requirements of decoding display and charging the pad or phone. This solution can support the connection of iPhone/iPad. 8 Compliance Information OEM/Integrators Installation Manual Important Notice to OEM integrators 1.This module is limited to OEM installation ONLY. 2.

The manufacturer of a limited module must describe, both in the filing and in the installation instructions, the alternative means that the limited module manufacturer uses to verify that the host meets the necessary requirements to satisfy the module limiting conditions. A limited module manufacturer has the flexibility to define its alternative method to address the conditions that limit the initial approval, such as: shielding, minimum signaling amplitude, buffered modulation/data inputs, or power supply regulation. The alternative method could include that the limited module manufacturer reviews detailed test data or host designs prior to giving the host manufacturer approval. This limited module procedure is also applicable for RF exposure evaluation when it is necessary to demonstrate compliance in a specific host. The module manufacturer must state how control of the product into which the modular transmitter will be installed will be maintained such that full compliance of the product is always ensured. For additional hosts other than the specific host originally granted with a limited module, a Class II permissive change is required on the module grant to register the additional host as a specific host also approved with the module. Explanation: The module is not a limited module. 2.5 Trace antenna designs For a modular transmitter with trace antenna designs, see the guidance in Question 11 of KDB Publication 996369 D02 FAQ Modules for Micro-Strip Antennas and traces. The integration information shall include for the TCB review the integration instructions for the following aspects:

layout of trace design, parts list (BOM), antenna, connectors, and isolation requirements.a) Information that includes permitted variances (e.g., trace boundary limits, thickness, length, width, shape(s), dielectric constant, and impedance as applicable for each type of antenna);

b) Each design shall be considered a different type (e.g., antenna length in multiple(s) of frequency, the wavelength, and antenna shape (traces in phase) can affect antenna gain and must be considered);

c) The parameters shall be provided in a manner permitting host manufacturers to design the printed circuit (PC) board layout;

d) Appropriate parts by manufacturer and specifications;

47 / 43 e) Test procedures for design verification; and f) Production test procedures for ensuring compliance. The module grantee shall provide a notice that any deviation(s) from the defined parameters of the antenna trace, as described by the instructions, require that the host product manufacturer must notify the module grantee that they wish to change the antenna trace design. In this case, a Class II permissive change application is required to be filed by the grantee, or the host manufacturer can take responsibility through the change in FCC ID (new application) procedure followed by a Class II permissive change application. Explanation: Yes, The module with trace antenna designs,refer to the RF Link schematic diagram and refer to PCB Layout. 2.6 RF exposure considerations It is essential for module grantees to clearly and explicitly state the RF exposure conditions that permit a host product manufacturer to use the module. Two types of instructions are required for RF exposure information:

(1) to the host product manufacturer, to define the application conditions (mobile, portable xx cm from a persons body); and (2) additional text needed for the host product manufacturer to provide to end users in their end-product manuals. If RF exposure statements and use conditions are not provided, then the host product manufacturer is required to take responsibility of the module through a change in FCC ID (new application). Explanation: This module complies with FCC RF radiation exposure limits set forth for an uncontrolled environment, This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body." This module is designed to comply with the FCC statement, FCC ID is: 2ACS5-H850. A list of antennas included in the application for certification must be provided in the instructions. For modular transmitters approved as limited modules, all applicable professional installer instructions must be included as part of the information to the host product manufacturer. The antenna list shall also identify the antenna types (monopole, PIFA, dipole, etc. (note that for example an omni-directional antenna is not considered to be a specific antenna type)). For situations where the host product manufacturer is responsible for an external connector, for example with an RF pin and antenna trace design, the integration instructions shall inform the installer that unique antenna connector must be used on the Part 15 authorized transmitters used in the host product. The module manufacturers shall provide a list of acceptable unique connectors. Explanation: The EUT has a Dipople Antenna.the customer can use the Dipople antenna 2.8 Label and compliance information Grantees are responsible for the continued compliance of their modules to the FCC rules. This includes advising host product manufacturers that they need to provide a physical or e-label stating Contains FCC ID with their finished product. See Guidelines for Labeling and User Information for RF Devices KDB Publication 784748. Explanation:The host system using this module, should have label in a visible area indicated the following texts: Contains FCC ID: 2ACS5-H850 2.9 Information on test modes and additional testing requirements Additional guidance for testing host products is given in KDB Publication 996369 D04 Module 48 / 43 Integration Guide. Test modes should take into consideration different operational conditions for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product. The grantee should provide information on how to configure test modes for host product evaluation for different operational conditions for a stand-alone modular transmitter in a host, versus with multiple, simultaneously transmitting modules or other transmitters in a host. Grantees can increase the utility of their modular transmitters by providing special means, modes, or instructions that simulates or characterizes a connection by enabling a transmitter. This can greatly simplify a host manufacturers determination that a module as installed in a host complies with FCC requirements. Explanation: Consider multi-transmission mode in the host. 2.10 Additional testing, Part 15 Subpart B disclaimer The grantee should include a statement that the modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed. Explanation: The host shoule be evaluated by the FCC Subpart B. 49 / 43 This radio transmitter [11554B-H850] has been approved by Innovation, Science and Economic Development Canada to operate with the antenna types listed below, with the maximum permissible gain indicated.
