Permalink of this page:
Overview
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.
Features
- Each two downstream port are independent isolation
