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 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.
ESD Level 4 Protection
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.
