Installing the USB-DIO96H
Unpacking
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device from its packaging, ground yourself using a wrist strap or by simply
touching the computer chassis or other grounded object to eliminate any stored static charge.
Contact us immediately if any components are missing or damaged.
Installing the software
Refer to the MCC DAQ Quick Start and the USB-DIO96H product page on our website for information about
the available software.
Install the software before you install your device
The driver needed to run the USB-DIO96H is installed with the software. Therefore, you need to install the
software package you plan to use before you install the hardware.
Connecting the external power supply
Power to the USB-DIO96H is provided with the +5 V external power supply (PS-5V3AEPS). You must
connect the external power supply before connecting the USB cable to the USB-DIO96H and your 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 2 on page 9 for the
location of this connector.
The PWR LED lights up when +5 V power is supplied to the USB-DIO96H. If the voltage supply is less than
+4.1 V or more than +5.6 V, the PWR LED does not turn on.
Installing the hardware
To connect the USB-DIO96H to your system, complete the following steps.
1. Turn your computer on.
2. Connect the USB cable to the USB connector labeled USB IN on the USB-DIO96H.
3. Connect the other end of the USB cable to a USB port on your computer or to an external USB hub that is
connected to your computer.
The USB LED turns on. Refer to Figure 2 on page 9 for the location of the USB LED.
Caution! Do not disconnect the device from the USB bus while the USB LED is on and the computer is
communicating with the USB-DIO96H. You may lose data and/or your ability to communicate
with the USB-DIO96H.
If the USB LED turns off
If the USB LED turns on 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.
