Technical overview

  • Four extended USB output ports; two switchable USB inputs allow sharing USB devices between two hosts.
  • Industrial-grade HUB chip inside the device.
  • Each USB port has ESD protection against electrical surges and data loss.
  • Over-voltage protection prevents high input voltages from damaging connected devices.
  • Multiple protection circuits are integrated: over-voltage, over-current, short circuit, over-temperature, reverse current, under-voltage lock-out, 8 kV ESD protection, and filtering.
  • The enclosure is made of industrial metal, is rugged, and includes mounting holes for easy installation.
  • Operating temperature range: -40°C to +85°C (no condensate).
  • LEDs LED1–LED4 indicate the status of each USB port: they light up when a device is connected and successfully enumerated. PWR indicates power supply.

Notes and version constraints

  • Exact firmware version or software compatibility is not specified; verify versions if issues occur.
  • If LEDs do not light up after connecting a device, first check that the correct power adapter is used.
  • Short-circuited USB devices can prevent the hub from working normally; test the device on another PC.
  • If current exceeds 1.2 A, short-circuit protection activates; disconnect the device to restore it.
