UPort 1200/1400/1600 Series Introduction

1-2

Overview

UPort 1200/1400/1600 Series products are easy to install and use. After installing the drivers on your PC,

connect the UPort to your computer, plug in your serial devices, and you’re ready to go. Programming is NOT

required, and you do not need to worry about IRQs, configuring a board, power requirements, or connection

schemes.

UPort 1200/1400/1600 Series products are compliant with USB 1.1, and 2.0 specifications, and meet the 480

Mbps high-speed requirement of Hi-Speed USB 2.0. Using your computer’s USB ports to connect serial devices

reduces the total cost of ownership, investment in hardware, and long term management and integration costs.

The UPort 1400 series converters support both bus power and external power. The UPort 1250I, UPort 1600-8,

and UPort 1600-16 converters support external power only. When using bus power, the UPort will get 500 mA

through the laptop’s or workstation’s USB port. When an external power adapter or power cord is used, the

UPort will only get 100 mA through the laptop or workstation’s USB port.

ADDC

(Automatic Data Direction Control) for

RS-485

ADDC™ (Automatic Data Direction Control) makes it easier to manage 2-wire RS-485 half-duplex connections,

eliminating the need for software interference. This means that it is not necessary to write extra code for

Windows applications to control the half-duplex protocol. ADDC™ intelligence is built into the UPort

1200/1400/1600 USB-to-serial converters that support the RS-485 serial interface.

ARDC (Automatic Recovery Data

Communication)

ARDC (Automatic Recovery Data Communication) makes it easier to auto recover data transmissions even if

the cable gets unplugged accidentally. This means the user does not need to worry about reconfiguring

complex settings to ensure smooth data transmissions. If the USB cable is accidentally unplugged, simply plug

it back into the same port and the converter will automatically reconnect with the host and continue to transfer

data. This feature not only reduces reconfiguration time, but also the probability of data loss.
