1. Before Using the Product
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 used to provide a digital signal I/O function on a
PC.
This product can input and output digital signals at 12 - 24VDC. This product features 32 channels of
Optocoupler isolated inputs (compatible with current sink output) and 32 channels of Op to coup ler
isolated open-collector outputs (current sink type). You can use 32 input signals as interrupt inputs.
Equipped with the digital filter function to prevent wrong recognition of input signals and output
transistor protection circuit (surge voltage protection and over current protection).
As there is compatible with PCI bus-compatible board PIO-32/32L(PCI)H and PCI Express
bus-compatible board DIO-3232L-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
- 32 channels of Optocoupler isolated inputs (compatible with current sink output) and 32 channels of
Optocoupler isolated open-collector outputs (current sink type)
This product has the 32 channels of Optocoupler isolated inputs (compatible with current sink output)
and the 32 channels of Optocoupler isolated open-collector outputs (current sink type) whose response
speed is 200µsec. Supporting driver voltages of 12 - 24 VDC for I/O.
(12 - 24VDC external circuit power supply is required separately.)
- Compatible to USB1.1/USB2.0
Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at HighSpeed (480 Mbps).
- USB HUB function
This product has the USB hub function.
Max. 4 DIO-3232LX-USB can be used in
1 USB port of PC. *1 When you use 4
or more DIO-3232LX-USB, you can do
by connecting DIO-3232LX-USB to the
another USB port of PC side. *2
Also, you can connect the CONTEC’s
USB device other than
DIO-3232LX-USB to the USB port of
DIO-3232LX-USB. *3*4

1. Before Using the Product
- Common terminal provided per 16 channels
Common terminal provided per 16 channels, capable of supporting a different external power supply.
- Optocoupler bus isolation
As the USB (PC) is isolated from the input and output interfaces by Optocouplers, this product has
excellent noise performance.
- You can use 32 input signals as interrupt request signals.
You can use 32 input signals as interrupt request signals and also disable or enable the interrupt in bit
units and select the edge of the input 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.
- Output circuits include zener diodes for surge voltage protection and poly-switches for overcurrent
protection.
Zener diodes are connected to the output circuits to protect against surge voltages. Similarly,
polyswitches are fitted to each group of 8channels outputs for over-current protection.
The output rating is max. 35VDC, 100mA per channel.
- Connectors are compatible with PCI/PCI Express bus-compatible board
As there is compatible with PIO-32/32L(PCI)H and DIO-3232L-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 When you use the USB port included on the DIO-3232LX-USB, use 5VDC power supply for self-power. For more details on the
connection with 5VDC power supply, refer to chapter2 - step3, “Connection with 5VDC Power Supply for Self-power”.
*3 Do not connect the device other than that of CONTEC’s USB to the USB port included on the DIO-3232LX-USB. Otherwise, this
may cause a failure or malfunction.
*4 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.
