Introduction

1.1. Summary

This product is a USB2.0 compatible terminal module that extends the analog output function of USB

port of PCs. This product features 4ch 16-bit analog output 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 output channels can be increased by purchasing an optional device module. Windows driver is

bundled with this product.

1.1.1. Features

- Conversion speed voltage : 10

µ

sec, current : 20

µ

sec, 16 bit resolution, analog output 4ch

This product includes analog outputs (voltage : 10µsec, current : 20µsec, 16 bit resolution, analog

output 4ch). Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at HighSpeed

(480 Mbps). The voltage or current output range set (voltage : +/-10V, current : 0 - 20mA). The

range is set by software and switch.

- 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 output 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.

- Output signal can be controlled by a clock or various trigger conditions

The output signal can be started and stopped by software trigger.

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

board).

- Easy to increase the output channels using an expansion module

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

for connection by stacking enables easy and compact system configuration.

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

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

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.

CONTEC provides download services (at http://www.contec.com/apiusbp/) to supply the updated

drivers and differential files.

Further details may be found in the help within supplied CD-ROM or the homepage of our company.

3.2. Setting a Module ID

The host computer distinguishes and keeps track of the modules of same model by assigning Module

IDs to them. Factory settings “00” can be used when only one module per model is connected to one

computer.

Each module should be assigned a unique Module ID in the range of 00 - 7Fh when several modules

with the same model are being connected.

There are two rotary switches, moreover, “x16” and “x1” represent high bits and low bits of Module

ID respectively.
