ADVANTECH BB-UH401 (01) PDF SUMMARY:

What should I have before I begin?

Before you begin, be sure you have the following: BB-UH401, BB-UH401-2KV USB to USB Isolator + USB Cable – 0.9 m (3 ft).

How much current do all models provide to attached downstream devices?

All models are USB bus powered and provide up to 100mA of current to attached downstream devices when they are attached to a Full Power (500 mA) USB host port.

What USB standard do the isolators comply with, and what data rates do they transfer data at?

The isolators comply with the USB 1.1 standard and transfer data at 12 Mbps or 1.5 Mbps. These data rates are preconfigured at the factory. You should select a model that is appropriate for your USB peripheral (full speed).

What isolation levels do the BB-UH401 and BB-UH401-2KV models provide?

Model BB-UH401 provides 4 kV isolation; Model BB-UH401-2KV provides 2 kV isolation.

What USB speed and isolation does the BB-UH401 model have?

BB-UH401 has Full (12 Mbps) USB speed and 4 kV isolation.

What USB speed and isolation does the BB-UH401-2KV model have?

BB-UH401-2KV has Full (12 Mbps) USB speed and 2 kV isolation.

How much current can the isolator provide to the attached downstream device?

The isolator can provide up to 100 mA of current to the attached downstream device. But, it cannot do this unless the USB host port is actually providing the specified Full Power (500 mA) to the isolator.

How can the operation of the isolator be verified?

Operation of the isolator can be verified by the “Power” ON LED. This indicator illuminates when the device is plugged in to a 500 mA port.

What is the maximum length of USB cables that can be used on the upstream and/or downstream ports?

You may use USB cables up to the standard 5 meter length on either the upstream and/or downstream ports.

What should be avoided for optimum isolation?

For optimum isolation, the computer/ host and the connected device should not use the same ground.
