About the Product
This product is a USB2.0-compatible terminal that allows your PC to expand the bidirectional I/O
functionality of digital signals. The terminal comes with 24 channels of non-insulated LVTTL-level
inputs/outputs. Inputs and outputs can be switched in blocks of eight by software. Its compact
appearance makes it suitable for PC application. In addition, no external power supply is required, as the
terminal operates on the USB bus power.
Windows driver is bundled with this product.
Possible to be used as a data recording device for LabVIEW, with dedicated libraries.
Features
- Non-insulated LVTTL-level inputs/outputs (Positive)
The product is provided with 24 non-insulated LVTTL-level I/O ports with a response speed of 200 nsec
(positive logic). This allows you to use a total of up to 24 channels of I/O digital signals in three sets of
eight.
- Compatible to USB1.1/USB2.0 and not necessary to power this product externally as the bus power is
used.
Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at HighSpeed (480 Mbps).
Not necessary to power this product externally as the bus power of USB is used.
- Easy-to-wire terminal connector adopted
Adoption of terminal connector (with screws) enables to achieve easy wiring.
- 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.
- LabVIEW is supported by a plug-in of dedicated library VI-DAQ.
Using the dedicated library VI-DAQ makes it possible to create each application for LabVIEW.
