- HDMI OUT (HDMI out): High-Definition Multimedia Interface output.
- BNC OUT (BNC out): Connettore BNC per uscita video.
- RS485: Serial communication port (GEN, IO-1, IO-2, 485A, 485B).
- Potenza in: 12V 2A DC power input.
5. Impostazione
Follow these steps to set up your HHD-101 decoder:
- Connetti alimentazione: Connect the provided 12V 2A power adapter to the "Power In" port (8) on the rear panel of the decoder. Plug the adapter into a power outlet. The red LED indicator should illuminate.
- Connessione di rete: Connect an Ethernet cable from your network router or switch to the "LAN" port (1) on the front panel. The green LED indicator should illuminate, indicating network activity.
- Connessione di uscita video:
- For HDMI output: Connect an HDMI cable from the "HDMI OUT" port (5) to your display device (e.g., TV, monitor).
- For CVBS/BNC output: Connect a BNC cable from the "BNC OUT" port (6) or an AV cable from the "AV OUT" port (4) to your display device.
- Audio Output (if applicable): If using AV OUT, audio will be carried through the composite cable. For HDMI, audio is embedded in the HDMI signal.
- RS485 Connection (Optional): If required for control or data transmission, connect your RS485 devices to the RS485 terminal block (7).
Once all connections are made, the device is ready for configuration and operation.
6. Istruzioni per l'uso
The HHD-101 decoder is designed to receive and decode various IP video streams. Operation typically involves configuring the decoder via its web interface to receive the desired stream.
6.1. Accedendo al Web Interfaccia
- Ensure the decoder is connected to your network as described in the Setup section.
- Find the IP address of the decoder. This can often be done using a network scanning tool or by checking your router's connected devices list. The default IP address is typically provided in the separate software utility or quick start guide.
- Aprire un web browser su un computer connesso alla stessa rete.
- Enter the decoder's IP address into the browser's address bar and press Enter.
- Log in using the default username and password (refer to the quick start guide or contact support if unknown).
6.2. Configuring IP Stream Decoding
All'interno del web interface, you will find options to configure the input stream. The HHD-101 supports multiple protocols:

Figure 6.1: Supported IP Protocols for HHD-101 Decoder.
- Navigate to the "Input Settings" or "Stream Configuration" section.
- Select the desired protocol (e.g., RTMP, RTSP, HLS, UDP).
- Enter the source IP address or URL of the video stream you wish to decode.
- Configure any additional parameters such as port numbers, authentication credentials, or specific stream IDs as required by your source.
- Save the settings. The decoder should begin receiving and outputting the video stream to the connected display.
6.3. Multi-View Decodifica
The HHD-101 supports decoding up to 4 channels for multi-view display. Consult the web interface documentation for specific instructions on configuring multi-view layouts and switching between sources.
6.4. Proprietary Protocol (P-P)
For ultra-low latency point-to-point transmission, the HHD-101 decoder can be used with Haiwei proprietary protocol encoders. This solution is available only when using both HaiweiTech encoders and decoders.

8. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| No power (Red LED off) | Adattatore di alimentazione non collegato o difettoso; problema con la presa di corrente. | Check power adapter connection. Try a different power outlet. Ensure 12V 2A power supply is used. |
| No network connection (Green LED off/flashing irregularly) | Ethernet cable disconnected or faulty; incorrect IP configuration; network issue. | Check Ethernet cable connection. Verify network settings and IP address. Restart router/switch. |
| Nessuna uscita video | Incorrect input stream URL/settings; display device not selected correctly; faulty HDMI/AV/BNC cable; display resolution incompatibility. | Verify stream URL and protocol in web interface. Ensure correct input is selected on your display. Try a different cable. Check if output resolution is supported by display. |
| Video stuttering or freezing | Insufficient network bandwidth; unstable source stream; decoder overload. | Check network speed and stability. Verify source stream quality. Reduce the number of simultaneous decoding channels if applicable. |
