Installing the software

Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data

Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-

Quick-Start.pdf.

Installing the USB-PDISO8

Before you connect the USB-PDISO8 to your computer, connect the external power supply that was shipped

with the device.

You can connect up to four compatible Measurement Computing USB products in a daisy chain configuration

to a single USB 1.1 port or USB 2.0 port on your computer.

Connecting the external power supply

Power to the USB-PDISO8 is provided with the +9 V external power supply (CB-PWR-9). You must connect

the external power supply before connecting the USB cable to the USB-PDISO8 and your computer.

If you are connecting more than one Measurement Computing USB product, make sure that you provide

adequate power to each device. Refer to the "Power limitations using multiple USB-PDISO8 devices" section

on page 3-7.

To connect the power supply to your USB-PDISO8, connect the external power cord to the power connector

labeled

POWER IN on the USB-PDISO8 enclosure (PWR IN on the board). Refer to on page 3-1 for

the location of this connector.

Figure 3-1

The

PWR LED illuminates green when +9 V power is supplied to the USB-PDISO8. If the voltage supply is

less than +6.5 V or more than +12.5 V, the

PWR LED does not light.

Do not connect external power to the POWER OUT connector

The power connector labeled POWER OUT on the enclosure (PWR OUT on the board) is used to provide power

to an additional Measurement Computing USB product. If you connect the external power supply to the

POWER OUT connector, the USB-PDISO8 does not receive power, and the PWR LED does not illuminate.
