Introduction

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 12-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.

Features

- Conversion speed 10µsec (voltage) or 20µsec (current), 12-bit

resolution, analog output 4ch

This product includes analog outputs (voltage : 10µsec, current :

20µsec, 12-bit, 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, +/-5V, 0 - 10V, 0 - 5V,

current : 0 - 20mA). The range is set by software.

- 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 output)

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.

1. Introduction

DAI12-4(USB)GY

- 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.

- 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 the module 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.

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.
