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.
