Introduction to USB Connectivity

Moxa’s UPort® line of USB connectivity products include a wide

range of solutions for connecting COM ports or USB ports to a PC

through the PC’s USB port. Moxa’s UPort® products are designed to

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

each port, come with LED indicators for easy monitoring, and are

even suitable for heavy-load applications. The UPort® product line

includes USB-to-serial converters with 1, 2, 4, 8, or 16 independent

RS-232, RS-422/485, and RS-232/422/485 serial ports for connecting

data acquisition equipment and many other types of serial devices to

notebooks and desktop PCs, and USB hubs with 4 or 7 USB ports for

expanding the number of built-in USB ports on a host PC.

USB-to-serial converters: UPort® 1000 and UPort® 2000 series

USB hubs: UPort® 200 and UPort® 400 series

Moxa’s UPort® 200 and UPort® 400 series of USB 2.0 hubs have

passed USB-IF (USB Implementers Forum) certification, which verifies

that products meet a number of strict electrical requirements for

Hi-Speed USB operation designed to the USB 2.0 specifications. This

means that the UPort® 200/400 series support Hi-Speed USB 2.0

UPort® products allow you to connect serial devices or USB devices

to your laptop or workstation through a USB (Universal Serial

For many applications, system integrators are moving towards using

either serial-to-Ethernet or USB-to-serial products to connect serial

devices to a PC. The overall costs of setting up an application is

reduced, not only from a short term hardware investment perspective,

but also by reducing costs associated with long term management and

Electrostatic discharge (ESD) could 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. In order to avoid serious

Moxa’s UPort® 1000/2000 series of USB-to-serial products include

models that support some or all of the RS-232/422/485 serial

interfaces. The full slate of RS-232 signals (TxD, RxD, DTR, DSR,

RTS, CTS, DCD) are supported, and both 2-wire and 4-wire RS-485

Some UPort® models support both bus power and external power

through the power adaptor. Bus power can be used with laptop and

workstation connections that support a 500 mA output for USB

for up to 480 Mbps USB transmission, are fully compliant with the

requirements for interoperability, provide enough power to attached

devices, and can transition back to high-speed operation from the
