# Setup with Herelink
#### **In this example:**
* Using ethernet telemetry to control Zio (gimbal and camera)
* Using HDMI to do video streaming from Zio to QGroundControl
### 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**
