This chapter provides information you should know before using the product.
About the Unit
This product is an USB2.0-compliant digital I/O unit that extends the input/output function of
bi-directional digital signal.
This product has up to 48 unisolated TTL-level input/output channels that is powered by the
equivalence to the mode 0 of i8255 chips, and you can use up to 48 channels of the input signals as
interrupt inputs. You can select the input/output by the application software in eight signals units (in
four signals unit for some inputs/outputs).
As there is compatible with PCI bus-compatible board DIO-48D2-PCI and PCI Express bus-compatible
board DIO-48D-PE in terms of connector shape and pin assignments, it is easy to migrate from the
existing system.
Windows driver is bundled with this product. Possible to be used as a data recording device for
LabVIEW, with dedicated libraries.
Features
- This product can be used to TTL-level input/output 48 points bi-directional digital corresponding to
the equivalence to the i8255 mode 0.
This product has up to 48 unisolated TTL-level input/output channels whose response speed is 200nsec
that is powered by to the equivalence to the mode 0 of i8255 device for general-purpose. You can select
the input/output by the application software in eight signals units (in four signals unit for some
inputs/outputs).
- You can use up to 48channels of the input signals as interrupt events.
You can use up to 48channels of the input signals as interrupt events and also disable or enable the
interrupt in bit units and select the edge of signals, at which to generate an interrupt.
- This product has a digital filter to prevent wrong recognition of input signals from carrying noise or
a chattering.
This product has a digital filter to prevent wrong recognition of input signals from carrying noise or a
chattering. All input terminals can be added a digital filter, and the setting can be performed by
software.
- Compatible to USB1.1/USB2.0
Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at HighSpeed (480 Mbps).
