1. Introduction

ADI12-8(USB)GY 1

1. Introduction

Summary

This product is a USB2.0 compatible terminal module that extends the analog input

function of USB port of PCs. This product features 8ch 12-bit analog input and is

isolated from the bus line to the PC. The signal lines can be connected directly to the

terminals on this product. To simplify use in embedded applications, this product

includes a bracket for attaching to a 35mm DIN rail. The number of input channels

can be increased by purchasing an optional device module. Windows driver is

bundled with this product.

Features

- Conversion speed 10µsec/ch+20µsec, 12bit resolution, Difference input 8ch

This product includes analog inputs (10µsec/ch + 20µsec, 12-bit, differential inputs,

8ch). Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at

HighSpeed (480 Mbps).

As this product can be used on any PC that supports USB, it is suitable for use with

notebook PCs that do not have PCI bus expansion slots. If using with a desktop PC,

this product can be connected easily without needing to open the computer's cover.

- Isolated from the bus by a digital isolator

This product is isolated by a digital isolator which improves the noise performance

with respect to the PC.

- Equipped with the buffer memory (256K data) which can be used in either

FIFO or ring format

This product includes buffer memory (256K data for analog input) which can be used

in either FIFO or ring format. You can perform analog input in the background,

independent of software and the current status of the PC.

- Windows compatible driver libraries are attached.

Using the attached driver library API-USBP(WDM) makes it possible to create

applications of Windows. In addition, a diagnostic program by which the operations

of hardware can be checked is provided.

Sampling can be driven by a clock or by various triggers

Sampling can be started and stopped by software and level comparison (compares the

level of a specified channel with a specified compare level value) triggers.

The sampling period can be controlled by the internal clock (high-precision timer

included on the board).

1. Introduction

2ADI12-8(USB)GY

- Easy to increase the input channels using an expansion module

Adding optional modules (up to 3 units) can easily increase the input channels. The

unique structure for connection by stacking enables easy and compact system

configuration.

- Screw-less connector plug facilitating wiring and plugging/unplugging

Wiring and plugging/unplugging are easy as the screw-less connector plug is used.

- Capable of being mounted on 35-mm DIN rails

This product is equipped with an attachment for mounting on 35-mm DIN rails on the

back, allowing this product to be attached onto and detached from DIN rails.

- LabVIEW is supported by a plug-in of dedicated library.

Using the dedicated library makes it possible to create each application for

LabVIEW.

Support Software

It is suggested that support software produced by our company should be used

according to the goal and development environment.

Driver Library API-USBP(WDM) (Bundled)

It is the library software, and which supplies command of hardware produced by our

company in the form of standard Win32 API function(DLL). Using programming

languages supporting Win32API functions, such as Visual Basic and Visual C++ etc.,

you can develop high-speed application software with feature of hardware produced

by our company.

In addition, you can verify the operation of hardware using Diagnostic programs.

For more details on the supported OS, applicable language and new information, please visit the

CONTEC’s Web site.
