USB-DIO96H User's Guide Installing the USB-DIO96H

Installing the hardware

Before connecting the USB-DIO96H to a computer, connect the external power supply that was shipped with

the device.

Connecting the external power supply

Power to the USB-DIO96H is provided with the +5 V external power supply (PS-5V3AEPS). Connect the

external power supply before connecting the USB cable to the USB-DIO96H and the computer.

To connect the power supply to the USB-DIO96H, connect the external power cord to the power connector

labeled POWER IN on the USB-DIO96H enclosure (P5 on the board). Refer to Figure 3 on page 10 for the

location of this connector.

TheUSB-DIO96H has a PWR LED which illuminates green when +5 V power is supplied. If the voltage supply

is less than +4.13 V or more than +5.59 V, the PWR LED does not light and power is not supplied to the board

components.

Connecting the USB-DIO96H to your system

To connect the USB-DIO96H to your system, connect the USB cable to an available USB port on the computer

or to an external USB hub that is connected to the computer. The USB cable provides communication to the

USB-DIO96H.

When you connect the USB-DIO96H for the first time, multiple Found New Hardware popup balloons open

when the operating system detects the device. When installation is complete, the USB LED should flash and

then remain lit. This indicates that communication is established between the USB-DIO96H and the computer.

If the USB LED turns off

If the USB LED is lit but then turns off, the computer has lost communication with the USB-DIO96H. To

restore communication, disconnect the USB cable from the computer, and then reconnect it. This should restore

communication, and the USB LED should turn back on.

Caution! Do not disconnect any device from the USB bus while the computer is communicating with the

USB-DIO96H, or you may lose data and/or your ability to communicate with the USB-DIO96H.

If your system does not detect the USB-DIO96H

Perform the following procedure if a "USB device not recognized" message appears when you connect the

USB-DIO96H:

 Unplug the USB cable from the USB-DIO96H.

 Unplug the external power cord from the POWER IN connector on the enclosure.

 Plug the external power cord back into the POWER IN connector.

 Plug the USB cable back into the USB-DIO96H.

Your system should now properly detect the USB-DIO96H hardware. Contact technical support if your system

still does not detect the USB-DIO96H.
