2. Feature
USB-303 is a USB 2.0 Full Speed(12Mbps) and Low Speed(1.5Mbps) compliant
USB hub which isolates between a USB host and two downstream ports with
3000VDC. Each of the two downstream ports are also isolated independently.
With USB-303, it can be expected to eliminate ground loops that can cause
measurement errors and equipment from surges, common-mode voltage, static
discharge, magnetic fields, and radio frequency interference.There is no need to
install any drivers. It works with every operating system such as Windows, Linux,
Mac OS X.
