1. Before Using the Product
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 sp eed is 20 0n sec
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

*2*3
- Connectors are compatible with PCI/PCI Express bus-compatible board
As there is compatible with DIO-48D2-PCI and DIO-48D-PE in terms of connector shape and pin
assignments, it is easy to migrate from the existing system. If the system of this product is created by the
digital I/O driver API-DIO(98/PC), it is required to replace it with API-DIO(WDM).
- Windows compatible driver libraries are attached.
Using the attached digital I/O driver API-DIO(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 make a LabVIEW application.
*1 This product cannot be stacked up for installation.
*2 Do not connect the device other than that of CONTEC’s USB to the USB port included on the DIO-48DX-USB. Otherwise, this may
cause a failure or malfunction.
*3 When connecting multiple units with USB HUB function and set up them, do one at a time and complete setup for the previous unit
before starting to do the next unit.

5. Function
This section describes the features of this product.
Each function described here can be easily set and executed by using the bundled API driver library. For
details, refer to API-DIO HELP available after installation.
Data I/O Function
This product supports the equivalence to the mode 0 of two i8255 chips, capable of input/output of up to
48 TTL-level active high signals.
I/O setup of the port
The I/O function of the port must be set properly before the board can input/output data correctly.
Writing a control word sets each port for either input or output.
The input/output setting can be achieved in eight signals unit for ports A and B and in four signals unit
(upper 4 bits and lower 4 bits) for port C.
CAUTION
Each port is assigned as an input port when the power is turned on.

Data I/O
I/O signals are TTL levels and positive logic.
Input
When input data is low level, [0] is input to the corresponding bit.
When input data is high level, [1] is input to the corresponding bit.
Output
When [0] is output to the corresponding bit, low level is output to the external part.
When [1] is output to the corresponding bit, high level is output to the external part.

5. Function
Digital Filter
Using this feature, this product can apply a digital filter to every input pin, thereby preventing wrong
recognition of input signals from being affected by noise or chattering.
Digital Filter Function Principle
The digital filter checks the input signal level during the sampling time of the clock signal. When the
signal level remains the same for the digital filter set time, the digital filter recognizes that signal as the
input signal and changes the signal level of the PC
If the signal level changes at a frequency shorter than the set time, therefore, the level change is ignored.

Set Digital Filter Time
Set the digital filter time to 0 - 20 (14h).
Setting the digital filter time to 0 disables digital filtering. It is set to 0 when the power is turned on.

5. Function
Interrupt Control Function
This product can use all of the input signals as interrupt request signals.
This product can generate an interrupt request signal to the PC when the input signal change from High
to Low or from Low to High.
When the digital filter (described above) is used, interrupt requests are generated by input signals that
have passed through the filter.
Disabling/enabling Interrupts
Interrupt mask bits can be used to disable or enable the individual bits for interruptions.
Once a certain bit has been interrupt-disabled, no interrupt occurs even when the corresponding input
signal changes its level.
To let interrupts occur, enable the corresponding interrupt mask bit for interruptions.
CAUTION
All of the interrupt mask bits are interrupt-disabled when the power is turned on.
Selecting the Edge of input signals, at which to generate an interrupt
The input signal edge selection bit can be used to set the input logic for interruption bit by bit.
If you set an input signal edge selection bit to 0, an interrupt occurs when the input value to the
corresponding bit changes from 0 to 1 (at the fa ll of th e inpu t s ign al from High to Low).
If you set an input signal edge selection bit to 1, an interrupt occurs when the input value to the
corresponding bit changes from 1 to 0 (at the rise of th e inpu t s i gn al from Low to High).
CAUTION
All of the input signal edge selection bits are set to 0 when the power is turned on.
Clearing the Interrupt Status and Interrupt Signal
Interrupt status bits are used to identify the input signal bit being used for requesting an interrupt.
When an interrupt status is input, the interrupt request signal and the interrupt status are cleared
automatically.
CAUTION
- All of the interrupt status bits are set to 0 when the power is turned on.
- If an interrupt mask bit has been set to disable interrupts, the interrupt status bit is not set even
when the input signal changes its level.
