Next, you will need to connect the pieces:

# Connect any sensors to the voltage inputs on the 1019.
# Connect the 1019 to the computer using a USB cable.
# Connect a switch or a piece of wire connecting ground to one of the digital input terminals.
# Connect an LED to one of the digital outputs by inserting the long LED wire into the digital output 0 and the shorter wire into ground.
# Connect the power supply to the barrel jack.
# If your power supply does not have a barrel connector, you can connect the wires to the terminal block beside the jack. Be careful to observe correct polarity when connecting the power supply's cables.
# You can connect other USB devices to the USB hub.

==Technical Details==
===Powering the PhidgetInterfaceKit===
The 1019 is not powered from the PC-USB bus. An external 6-15V supply must used to power the 1019 and any attached USB devices. However, the USB hub will not actually be powered until a USB connection is made.  The reason for this is that the voltage regulator chip on the 1019 is what routes power to the hub, and it gets its power from the USB line. The 1019 will consume a maximum of 10mA from the USB host cable - allowing it to be directly connected to small hosts that do not provide full USB power.

Connecting additional USB devices to the 1019 is as easy as plugging them into the on-board 6-port hub.  Each USB port on the hub has a maximum current supply of 500mA.  Ensure the power supply selected has a high enough current output to supply the required current to all external USB devices as well as the 1019 and any sensors or devices connected to it.  The worst case requirement is 3 Watts input power per USB device. A 24 Watt 12VDC / 2 Amp power supply would be more than sufficient.

The USB Hub actually has 7 ports, but only 6 of them are used for connecting additional devices since one port is dedicated to the internal 8/8/8 InterfaceKit.

The USB Hub is a full-speed hub  with a transfer rate of 12Mbits/second. We chose to go with  a full speed implementation since it is fast enough to handle traffic from Phidgets; an added benefit is lower power consumption.

To summarize the power distribution of this board:
* Each USB port has 500 mA available
* All analog inputs share a total of 500 mA
* The digital outputs, +5V terminals, USB controller, and pull-ups all share a total of 500 mA
* The power inbound from the USB line does not contribute to any of the above

===Connections===
The ports and terminal blocks on this board are labelled on the underside to save space:

===Chaining the USB Hubs===
The 1019 follows USB specifications and can be daisy chained to the maximum hub depth of 5. A sixth 1019 with a hub plugged into the fifth hub will not be usable at all because the 1019 portion is connected after the hub. However, other Phidgets plugged into the fifth hub will operate normally.
