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.
