3. Arahan Persediaan
- Kenal pasti Pelabuhan: Locate an available USB-C port on your host device (e.g., laptop, desktop computer, Android phone/tablet).
- Connect Isolator to Host: Plug the USB-C male connector of the SH-G01C isolator into the USB-C port of your host device.
- Connect Peripheral Device: Connect your USB peripheral device (e.g., HiFi DAC, audio interface, development board) to the USB Type A female port on the SH-G01C isolator.
- Sahkan Sambungan: The device is plug-and-play and typically requires no driver installation. Your operating system should automatically recognize the connected peripheral device through the isolator.

4. Arahan Operasi
Once connected, the DSD TECH SH-G01C operates transparently, providing a high-speed isolated USB 2.0 connection. It functions as an intermediary device, ensuring that electrical noise and ground loops from the host system do not interfere with the connected peripheral. This is particularly beneficial for audio equipment where noise can degrade sound quality.
Noise Reduction Principle
The isolator uses advanced chip technology (ADI ADUM3165) to electrically separate the ground planes of the host and peripheral devices. This prevents unwanted current flows (ground loops) that often manifest as hums, buzzes, or static in audio systems, or as data corruption in sensitive data transfer applications.

5. Penyelenggaraan
The DSD TECH SH-G01C is a low-maintenance device. To ensure its longevity and optimal performance:
- Pastikan peranti bersih dan bebas daripada habuk. Gunakan kain lembut dan kering untuk pembersihan.
- Elakkan daripada mendedahkan peranti kepada suhu yang melampau, kelembapan atau cahaya matahari langsung.
- Do not apply excessive force when connecting or disconnecting cables to prevent damage to the connectors.
- Simpan peranti di tempat yang selamat apabila tidak digunakan untuk mengelakkan kerosakan fizikal.
6. Penyelesaian masalah
- Peranti Tidak Dikenali: Ensure both the USB-C connector to the host and the USB-A connector to the peripheral are securely plugged in. Try connecting the peripheral directly to the host to confirm the peripheral is functional.
- Noise Persists: While the SH-G01C is designed to eliminate ground loop noise, other sources of interference may exist. Ensure all audio cables are shielded and properly routed away from power cables. Test the setup with different USB ports or host devices if possible.
- Sambungan Terputus-putus: Check for any physical damage to the cables or connectors. Ensure the host device's USB-C port is functioning correctly.
- Pemindahan Data Lambat: The SH-G01C supports USB 2.0 High-Speed (480Mbps). If you are experiencing slower speeds, ensure your peripheral device is also operating at USB 2.0 speeds and that your host system's USB-C port is configured for optimal performance.
