inserting component leads and jumper cables into pins on the breadboard.
The pins are arranged in groups of 5. The 5 pins in each group are electrically
connected to each other at the back of the board. You connect leads and cables
together by inserting them into pins within the same group.
•
Power rails at the top and bottom are marked with red (+) and blue (–) stripes. The
groups in each rail are electrically connected along the entire length of the stripe.
•
The remaining 5-pin groups on the board are labeled with numbers and letters.
Each group is electrically isolated from the others.

Interconnections at back of board (normally
hidden). The 5-pin groups in each power rail are
interconnected. All other 5-pin groups are
isolated.
The gap at the center of the breadboard allows easy connection of electronic
components provided as dual-inline packages.
You use jumper cables between the Hub and the breadboard to power breadboard
components and to control or monitor them through program code. The Hub has 20
labeled pins, including 10 signal pins, 8 ground pins, one 3.3V power pin, and one 5.0V
power pin.

Using an Auxiliary Power Source
Normally, the TI-Innovator™ Hub and its connected components draw power from the
host calculator or computer, through the DATA connector. Certain components, such as
the optional Servo Motor, require more power than a calculator can provide reliably.
The PWR connector on the Hub lets you connect an auxiliary power source. You can use
the TI Wall Charger or the External Battery Pack.
TI Wall Charger (included with the Hub)
• Plugs into a wall outlet.
• Does not use batteries.
External Battery Pack (sold separately)
• Rechargeable.
• Has On/Off button with a row of LEDs that
momentarily indicate the battery charge
when you turn the battery on.
• Turns itself off after being disconnected
from the Hub for about 3 minutes.
Note: To recharge the External Battery Pack,
disconnect it from the Hub and then connect
it to the TI Wall Charger using the USB
Standard A to Micro cable. Do not use the
External Battery Pack as an auxiliary power
source while it is being charged.
Connecting the Power Source
1. Identify the Micro connector on the USB
Standard A to Micro auxiliary power cable.
2. Insert the Micro connector into the PWR
connector at the top of the Hub.
3. Insert the free end of the cable (the "A" connector) into the USB port on the power
source.
23
4. Turn on the power source:
-
If using the TI Wall Charger, plug it into a wall socket.
If using the External Battery Pack, press the power button.
An auxiliary power LED on the Hub glows to show that the Hub is receiving auxiliary
power.
5. Connect the TI-Innovator™ Hub to the host calculator, using the USB Standard A to
Mini-B cable.
6. Connect the I/O Module or breadboard component to the Hub.

Troubleshooting
I don't see the green LED when I connect TI-Innovator™ Hub.
•
Make sure that the calculator is turned on.
•
If you are using a USB Unit-to-Unit (Mini-A to Mini-B) cable to connect to a
calculator, make sure to connect the "B" end of the cable to the DATA connector at
the bottom of the Hub. Reversing this cable prevents the Hub from receiving
power.
•
Make sure your calculator or computer meets the System Requirements (page 1).
•
Make sure the end of the USB cable connected to the calculator is inserted
completely.
How do I turn the Hub off?
1. Turn off the host calculator or computer.
– OR –
Disconnect the USB cable.
2. Disconnect any auxiliary power source connected to the PWR port on the Hub.
Why does my program give me a syntax error?
•
If you have pasted code from an external source or text editor, it might contain
"curly" quotation marks ( “ ...” ) in places that require straight quotes ("..."). You
may need to replace some or all of the curly quotes.
•
The syntax rules are slightly different between the TI CE graphing calculator and
TI-Nspire™ CX technology. Code originally created for one platform may need to be
modified to work on the other.
•
On the TI CE graphing calculator, make sure you don't have a space character at the
end of a line of code. To find these trailing spaces in a line, move the cursor to the
line and press y ~. Adjacent spaces in code can also cause a syntax error.
How do I stop a program that becomes unresponsive?
•
TI CE graphing calculator: Press the É key.
•
TI-Nspire™ CX Handheld: Hold down the c key and press · repeatedly.
•
Windows®: Hold down the F12 key and press Enter repeatedly.
•
Mac®: Hold down the F5 key and press Enter repeatedly.
Why do I get an error when I try to update the TI-Innovator™ Sketch?
•
For sketch updating, make sure you are using the USB Standard A to Micro cable,
not the USB Standard A to Mini-B cable. Connect the micro end of the cable to the
PWR connector at the top of the Hub.
•
Make sure you are using one of the Web browsers required for updating. See
Updating the Hub Software (page 6).

used to detect small objects, such as a cup, place the Rover within 1 meter of the
object.
•
For best results, leave the Slide Case off of your graphing calculator.
•
For best performance, use Rover on the floor, not on tables. Damage may occur
from Rover falling off a table.
•
For best performance, use Rover on a hard surface. Carpet may cause the Rover
wheels to catch or drag.
•
Do not turn the Holder pegs on the Calculator Platform without lifting them first.
They could break.
•
Do not use the marker as a lever to pull or push the Rover.
•
Do not unscrew the case enclosure on the bottom of the Rover. Encoders have
sharp edges that should not be exposed.
•
Do not move Rover after executing a program. The internal gyroscope may
unintentionally try to get the Rover back on track using the initial location.
28
•
When inserting the Breadboard Ribbon Cable into the Hub Breadboard Connector, it
is critical that you insert the cable correctly. Make sure the red (dark) wire pin is
inserted into the 5v hole on the Hub's Breadboard Connector.
