<b>Introduction</b>
Externally powered USB hubs are the only way to guarantee the broadest compatibility with USB devices. The UPort™ 404 and UPort™ 407 are industrial-grade USB 2.0 hubs that expand 1 USB port into 4 and 7 USB ports, respectively. The hubs are designed to provide true USB 2.0 Hi-Speed 480 Mbps data transmission through each port, even for heavy-load applications. USB-IF certified and fully compliant with the USB Plug & Play specification, the UPort™ 404 and UPort™ 407 USB hubs provide a full 500 mA of power per port to ensure that your USB devices will function properly. Support for 12-40 VDC power also makes these USB hubs ideal for mobile applications.
<b>USB-IF Certification</b>
The UPort™ 404 and UPort™ 407 industrial-grade USB 2.0 hubs have passed USB-IF (USB Implementers Forum) certification. USB-IF verifies a number of strict electrical requirements for high-speed hubs designed for the USB 2.0 specification. This means that the UPort™ 404 and UPort™ 407 USB hubs support up to 480 Mbps USB 2.0 transmission, are fully compliant with interoperability requirements, have enough power for devices to function, and provide a successful transition back to high-speed operation from suspend mode.
<b>ESD Level 4 Protection</b>
Electrostatic discharge (ESD) can be as severe as having more than one thousand volts of ESD with a high rise time (dv/dt) break through the junction layer of protective devices. To guard against serious damage, Moxa's UPort™ 404/407 USB hubs provide ESD level 4 (contact 8 KV, air 15 KV) protection, which increases the quality and value of the user’s end-product.
