2. Setup Instructions
Follow these steps to set up your Jancane USB 3.0 Switch Selector:
- Connect USB Devices: Plug your 4 USB peripheral devices (e.g., keyboard, mouse, printer, USB drive) into the "USB OUT" ports on the front of the switch selector.
- Connect Computers: Use the provided USB 3.0 A to A cables to connect your two computers (PC1 and PC2) to the respective "PC1" and "PC2" input ports on the rear of the switch selector.
- Optional Power Connection: If you are connecting high-power USB devices (e.g., external hard drives, digital video cameras), connect a standard 5V Micro USB power adapter (not included) to the "DC 5V" port on the side of the switch selector. This ensures stable operation for all connected devices.
- Power On: Ensure both connected computers are powered on. The switch selector does not require a separate power button; it draws power from the connected computers or the optional external power supply.
