Introduction to USB Connectivity

Industrial USB

Moxa’s USB 2.0 Hubs First to Receive USB-IF Certiﬁcation

Important Considerations for USB Devices in Industrial Applications

USB (Universal Serial Bus) is the most popular interface in the IT

industry today, In recent years, USB has also gained popularity in

industrial applications as more and more devices support the interface.

But industrial operations are more demanding than your typical office

application and require additional considerations. For example, a

factory floor may be subject to extreme temperatures that are too hot

Although any vendor can design a USB product that meets the USB

specifications, the product may not have been tested for flaws. When

considering which USB product to buy, you should check to make sure

that the product has received USB-IF certification, and that the product

for a consumer-grade USB hub to handle. Industrial applications also

require a higher level of reliability because system downtime is not

only costly but potentially dangerous. To ensure that your USB devices

meet these demands, system engineers should consider the following

factors when selecting a USB device for industrial environments.

Moxa’s new line of industrial-grade USB hubs, the UPort® 200 and

UPort® 400 series, are the world’s first to receive USB-IF certification

for reliable peripheral plug-and-play devices. The hubs are designed to

provide true USB 2.0 Hi-Speed 480 Mbps data transmission through

each port, even for heavy-load applications. As USB-IF certified

products, the UPort® 200 and UPort® 400 series have passed high

speed compliance testing and are eligible to bear the official USB logo.

The UPort® 200 and UPort® 400 series are external

plug-and-play hubs that can be plugged into a standard USB port for

instant peripheral device connectivity. For industrial networks, high

reliability can never be compromised. As defined by the USB-IF (USB

Implementers Forum), certification for Moxa’s UPort® USB hubs

guarantees:

• 480 Mbps USB 2.0 transmissions

• Device accessibility

• Full power for connected devices

• High-speed operation from suspend mode

is listed in the USB-IF Integrators List on the USB-IF website. Products

that are certified to carry the USB logo have been tested for both

reliability and interoperability.

To guard against serious damage, the UPort® 200 and UPort® 400

series have doubled their ESD protection from Level 2 (4 KV) to Level

4 (8 KV) to provide 8 KV of ESD protection for direct contact and 15

KV of ESD protection for contact through the air. Wide temperature

models (UPort® 200-T and UPort® 400-T) are also available for use

in extreme temperatures ranging anywhere from -40 to 85°C.
