Quatech Freedom USB Adapter User’s Manual

Introduction

Introduction

Note: These products comply fully with USB Specification version 1.1 and are fully supported under Windows 98/ME/XP/2000/NT4.

Note: The 16550 is well suited for applications involving high data rates and for heavy multitasking environments. The larger FIFO allows each read/write access to the UART to move more data, resulting in fewer interrupts and less processor time spent servicing the UART.

This Users Manual describes how to setup and install your Quatech Freedom USB Adapter.

The Quatech SSU-100, DSU-100, QSU-100, ESU-100, and HSU-100, respectively, provide one, two, four, eight, and sixteen independent RS-232 serial interfaces to the host PC via the Universal Serial Bus (USB) port.

The Quatech DSU-200/300, QSU-200/300, ESU-200/300, and HSU200/300, respectively, provide two, four, eight, and sixteen independent asynchronous serial interfaces via the USB port. Each of these interfaces can be used as desired for either RS-422 or RS-485 communications.

For convenience, this manual refers to all these products as Freedom USB unless otherwise noted.

The following table details the port and connection configuration for all the Freedom USB devices.

Each adapter comes standard with 16550 Universal Asynchronous Receiver/Transmitters (UARTs) containing 16-byte First In First Out (FIFO) storage devices. These FIFOs, in conjunction with the USB micro controller FIFOs, help to relieve the CPU of excessive interrupts by buffering received and transmitted data. This configuration allows each channel (either two or four) to obtain data rates up to 460.8 kbps. The adapters are USB bus-powered; therefore no external power supply is required.

The Freedom USB products are Plug-and-Play devices and require no hardware configuration. Your computer's BIOS or operating system automatically configures the ports when you install the device.

Introduction

Quatech Freedom USB Adapter User’s Manual

System requirements

Note: The 16-port units (HSU100/200/300) require two USB ports. All the other units use only one USB port.

Quatech’s serial USB adapters require the Windows 98/Me/XP/2000/NT4 operating system and an IBM or IBM-compatible PC with a standard USB port or an add-in USB host adapter. Contact our sales department for details on current software offerings. Most device drivers are available for download from the Quatech World Wide Web site at http://www.quatech.com/.

Features

Quatech offers an IND option, or surge-suppression board upgrade, to provide improved performance and industrial-grade reliability.

IND option - surge suppression upgrade

Table 2 differentiates between the Freedom USB-1/2/300 part numbers with and without the IND option.

The IND option provides essential protection for reliable use in an industrial environment. Each communication line has a surge suppressor capable of sustaining up to 40-A, 20- s peak transient surges, a clamping voltage of 30 V (15.1 V for 200/300 units), and a peak energy dissipation of 0.1 Joules.

Quatech Freedom USB Adapter User’s Manual

Installing the software

Installing the Freedom USB

Note: The installation process takes place in two stages: the serial adapter board and then the serial ports.

Caution! Be sure to allow the installation process to finish without interruption. If you stop the process before the adapter board(s) and all of the serial ports are installed, you will corrupt the installation.

This section explains how to install the Freedom USB under different operating systems. Please locate and follow the procedure for your computer’s operating system.

Windows maintains a registry of all known hardware installed in your computer in which it keeps track of all of your system resources, such as I/O locations, IRQ levels, and DMA channels. The Add New Hardware Wizard utility helps you to add new hardware and updates this registry.

The Freedom USB includes an INF configuration file to allow easy configuration in the Windows environment. Windows uses the INF file to determine the system resources required by the Freedom USB, searches for available resources to fill the boards requirements, and then updates the hardware registry with an entry that allocates these resources.

The Freedom USB also includes Windows device drivers that enable the Freedom USB serial ports to appear to Windows as standard COM ports.

Installing under Windows XP

Follow these steps to install the Freedom USB under Windows XP.
