1. Before Using the Product
This chapter provides information you should know before using the product.
About the Board
This product is a PCI Express bus-compliant interface board that supports transfer by bus mastering and
performs input/output between the external device and digital signal. This product features unisolated
LVTTL level (Operating voltage : 3.3V) I/O 32channels and you can select input / output in 16 units.
Bus master transfer makes it possible to sample quickly large data with transfer rate at 50MHz
maximum. It can be used as a pattern generator that outputs arbitrary digital patterns at high speed.
It can also be used as a general-purpose I/O board when bus mastering is not used.
Windows driver is bundled with this product.
Using the dedicated library VI-DAQ makes it possible to create each application for LabVIEW.
Features
- 32channels of unisolated LVTTL level I/O (32 input channels / each 16channels for I/O / 32 output
channels are selected.)
This product has the 32channels (operating voltage 3.3VDC, positive logic) of unisolated LVTTL level
I/O whose response speed is 20nsec. They can be used for 32bit input, 16bit input plus 16bit output, or
for 32bit output.
Other than I/O bit, this product has the control signal (clock, start, stop and handshake signal (REQ,
ACK) that can control starting and stopping the sampling (input) / generating (output)).
- Sampling and generating with transfer rate at 50MHz maximum
Bus master transfer makes it possible to sample (input) or generate (output) large data with transfer rate
at 50MHz maximum. As the sampling and generating features have their own bus mastering blocks
each made up of two independent channels, the board can generate 16 signals while sampling 16
signals.
- A synchronization control connector is provided for synchronized control of multiple boards.
A synchronization control connector is provided for synchronized control of up to 16 boards. It is also
easy to synchronize operation with other CONTEC boards that have a synchronization control
connector.
- You can use Max. 4 input signals as interrupt request signals at the time of using the general-purpose
I/O.
You can use Max. 4 input signals as interrupt request signals and also disable or enable the interrupt in
bit units at the time of using the general-purpose I/O.
- Windows compatible driver libraries are attached.
Using the attached driver library API-PAC(W32) 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. Before Using the Product
2DIO-32DM3-PE
- You can use pull-up and the voltage selection.
At input points and control signals, you can use pull-up. In addition, the pull-up voltage can be selected
from the 3.3V and 5V. This feature allows you to easily connect and equipment with an output point of
the sink type.
- Functions and connectors are compatible with PCI compatible board PIO-32DM(PCI) and PCI
Express compatible board DIO-32DM2-PE, DIO-32DM-PE.
The functions same with PCI compatible board PIO-32DM(PCI) and PCI Express compatible board
DIO-32DM2-PE, DIO-32DM-PE are provided. In addition, as there is compatibility in terms of
connector shape and pin assignments, it is easy to migrate from the existing system.
- LabVIEW is supported by a plug-in of dedicated library.
Using the dedicated library makes it possible to make a LabVIEW application.
