Introduction

The UPort® 204 and UPort® 207 are entry-level 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. The UPort® 204 and UPort® 207 have received the USB-IF Hi-Speed certification and are fully plug and play. 500 mA of power per port ensures that your USB devices will function properly, and using 12 to 40 VDC of power makes them ideal for mobile applications. Externally powered USB hubs are the only way to guarantee the broadest compatibility with USB devices.

USB-IF Certification

The UPort® 204/207 USB 2.0 entry-level USB hubs are USB-IF (USB Implementers Forum) certified. The USB-IF certification confirms compatibility with a number of electrical requirements for the Hi-Speed USB operation of USB hubs designed in accordance with the USB 2.0 specifications. This means that the UPort® 204/207 supports Hi-Speed USB 2.0 for up to 480 Mbps USB transmission, which is compliant with interoperability requirements, has enough power for devices to function, and provides a successful transition back to high-speed operation from the suspended state.

ESD Level 4 Protection

Electrostatic discharge (ESD) could be as severe as having more than 1,000 volts of ESD with a high rise-time (dv/dt) breaking through the junction layer of protective devices. In order to avoid serious damage, our UPort® 204/207 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.
