### Step 1: CREATE CONFIG FILES ON MICRO SDCARD #### **1.1 Create file for set up a static ip address for Zio**
**File name: payload\_setup.txt** **File Content:** ```markdown /*PAYLOAD CONFIGURATION*/ # IP address of Payload ZIO_ADDR = 192.168.144.200 NETMASK = 255.255.255.0 # IP adress of UDP stream receiver STREAM_VIDEO_TO = 192.168.144.104:5000 ``` On the above example: * Zio IP: 192.168.144.200 * Zio stream video to the IP: 192.168.144.104 at port 5000 -> we not use video streaming via ethernet > ***NOTE:*** when Zio starts up without detecting the file payload\_setup.txt in the memory card, Zio will automatically reset to the default IP (192.168.50.100) #### 1.2 **Create Config Herelink Ethernet File** **File Name: zio\_herelink\_eth.conf**
**File Content: (Copy exactly below)** ```markdown # Herelink air-unit endpoint # This endpoint will connect to Herelink air-unit [UdpEndpoint Ethernet_MavIn_Herelink] Mode = Normal Address = 192.168.144.10 Port = 14552 Group = Mavlink_In # Ground control station endpoint # Please setup an UDP commlink on QGroundControl to this endpoint [UdpEndpoint GCS_Ethernet_Endpoint] Mode = Normal Address = 192.168.144.11 Port = 14565 Group = Mavlink_Out ``` > ***NOTE:***: After adding two files "payload\_setup.txt" and "zio\_herelink\_eth.conf" to micro SDcard, please reboot the Zio to apply changes. #### Step 2: SETUP ON QGROUNDCONTROL APP 2.1 Disable all AutoConnect in General.
2.2 Navigate to Comm Links, add new Comm link for Ethernet telemetry
2.3 Create the new link as following
**On the above example:** ```markdown Name: Zio Type: UDP Listening Port: 14565 Target Hosts: 192.168.144.200:14565 (Zio's IP) ``` #### 2.4 Check the new Ethernet connection * Connect the HDMI to Herelink v1.1 * Video Stream info will show as below after configuring successfully
**(Do not change)** ```markdown Video Source: RTSP Video Stream RTSP URL: rtsp://192.168.144.10:8554/H264Video Aspect Ratio: 1.777777 ``` **Successful connection**
--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.gremsy.com/payloads/zio/ethernet-telemetry-payload-control/setup-with-herelink.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
