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 features 128 channels of Optocoupler isolated inputs (compatible with current sink output)

and 128 channels of Optocoupler isolated open-collector outputs (current sink type).

The input point and the output point are common. Therefore each I/O pin can use as an input pin or an

output pin. 24VDC external circuit power supply is required to drive a photo coupler.

You can use 16 input signals as interrupt request signals. Equipped with the digital filter function and

output transistor protection circuit (overcurrent protection).

Windows driver is bundled with this product. Possible to be used as a data recording device for

LabVIEW, with dedicated libraries.

Features

- Bidirectional signal control is possible, because digital input point and a digital output point are

common.

The I/O pin can use as an input pin or an output pin without changing the wire connection.

- 128 channels of Optocoupler isolated inputs (compatible with current sink output) and 128 channels

of Optocoupler isolated open-collector outputs (current sink type)

This product has the 128 channels of Optocoupler isolated inputs (compatible with current sink output)

and the 128 channels of Optocoupler isolated open-collector outputs (current sink type) whose response

speed is 200µsec. Supporting driver voltages of 24 VDC for I/O.

(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-128SLX-USB can be used in 1 USB port of PC.

*3 When you use 4 or more DIO-128SLX-USB, you can do by connecting DIO-128SLX-USB to the

another USB port of PC side.

Also, you can connect the CONTEC’s USB device other than DIO-6464LX-USB to the USB port of

DIO-6464LX-USB. *1*2

- 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 16 input signals as interrupt request signals.

You can use 16 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 overcurrent protection circuit.

Overcurrent protection circuits are fitted to each group of 8ch outputs.

The output rating is max. 24VDC, 100mA per channel.

- Windows compatible driver libraries are attached.

Using the attached driver libraries 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 make a LabVIEW application.

*1 Do not connect the device other than that of CONTEC’s USB to the USB port included on the DIO-128SLX-USB. Otherwise, this

may cause a failure or malfunction.

*2 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.

*3 This product cannot be stacked up for installation.

Step 3 Installing the Hardware

Under Windows, information about the converter needs to be detected by the OS. This is called

hardware installation.

To use more than one of this product, make sure to install them one by one, setting each unit after

completing the previous one.

Connection with 5VDC Power Supply for Self-power

This product must be connected with 5VDC power supply (in a self-powered state).

Connect with 5VDC power supply by using +5VDC input pin.

Figure 2.2. +5 VDC Input Terminal Pinouts

When using the attached AC adapter [POA200-20-2], please connect directly to the input terminals.

When the accompanying power connector (MC1,5/3-ST-3,5, suitable cable: AWG28 - 16) is used to

supply power to this unit, strip the end of the suitable cable and insert it to the power connector before

firmly securing it using a screw.

Figure 2.3. Connecting the AC Adapter POA200-20-2

When a power supply for installation on a DIN rail is used, connect the unit using the accompanying

power connector MC1,5/-ST-3,5.

- Connect 5VDC power supply to the main unit. Next, connect the USB cable to the PC. Do not

turn it on or off when using. If you remove, USB cable is first and then 5VDC power supply.

- When the USB module is not used, leave the AC adapter unplugged.

- Continuously using the AC adapter heated affects its life.

- Use the AC adapter not in a closed place but in a well-ventilated place not to be heated.

- Do not remove the power connector [MC1,5/3-ST-3,5] attached to the AC adapter.
