1. 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 10
µ
sec (voltage) or 20
µ
sec (current), 12-bit
resolution, analog output 4ch
This product includes analog outputs (voltage : 10
µ
sec, current :
20
µ
sec, 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.
