TI-Nspire™ Lab Cradle
The TI-Nspire™ Lab Cradle is a device used with TI-Nspire™ handhelds,
TI-Nspire™ software for computers, or as a stand-alone tool to collect data.
The Lab Cradle supports all TI sensors. It also supports more than 50 analog and digital Vernier DataQuest™ sensors, including motion detectors and photogate sensors. To see the full list of supported sensors, go to education.ti.com/education/nspire/sensors.
Important:
The TI-Nspire™ CM-C Handheld is not compatible with the Lab
Cradle and only supports the use of a single sensor at a time.
The Lab Cradle comes pre-loaded with its own operating system (OS). The
TI-Nspire™ 3.0 operating system for handheld and computer software has been preset to recognize the Lab Cradle so you can start using it immediately.
Note:
Any TI-Nspire™ OS earlier than 3.0 will not recognize the Lab Cradle. For more information about upgrading a handheld OS, see Getting Started with the
TI-Nspire™ CX Handheld or Getting Started with the TI-Nspire™ Handheld.

Setting up the Lab Cradle for Data Collection
Before you can use the Lab Cradle to collect data, you must connect it to a handheld or computer to define the collection parameters.
Attaching the Lab Cradle
To attach a handheld to a Lab Cradle, slide the handheld into the connector at the bottom of the Lab Cradle. To lock the handheld to the Lab Cradle, push the lock up with the handheld facing up. Push the lock down to release the handheld.
You can also connect to a handheld by plugging the handheld’s cable into the
Lab Cradle’s mini-USB port. This connection lets you transfer data from the Lab
Cradle to the handheld when you have collected data in the stand-alone mode.
To connect the Lab Cradle to a computer, plug the cable’s mini-USB connector into the Lab Cradle’s mini-USB port. Then plug the cable’s standard USB connector into the computer’s standard USB port.
Defining Collection Parameters
You must have the TI-Nspire™ software loaded on the computer or handheld.
Use the built-in Vernier DataQuest™ app to:
• Modify sensor settings.
• Set up data collection modes.
• Define triggering.
For more information, see the TI-Nspire™ Data Collection and Analysis
Guidebook.
TI-Nspire™ Lab Cradle 7
Using the Lab Cradle
The Lab Cradle can be used in the classroom or remotely. Collect the data with the Lab Cradle, and then retrieve the data later. Store the data on the Lab
Cradle until you return to the classroom, and then transfer it to a handheld or computer for analysis.
Using the Lab Cradle with a Handheld
You can connect the Lab Cradle to your handheld to collect or retrieve data.
Using the Lab Cradle with a Computer
The Lab Cradle works with all Windows® and Mac® operating systems currently supported by the TI-Nspire™ Teacher and Student computer software.
Using the Lab Cradle as a Stand-Alone Data Collection Tool
You can use the Lab Cradle in stand-alone mode to collect data either manually or automatically. Press the trigger button to manually start and stop data collection when in stand-alone mode.
Note:
For long-term data collections TI recommends you use an AC adapter for a handheld or a remote collection device such as the Lab Cradle.
Before collecting data, set up the data collection parameters using the Vernier
DataQuest™ app or use the sensor’s default settings. If you do not change the parameters and use a single sensor, the Lab Cradle collects data using the sensor’s default settings. If you use multiple sensors, the Lab Cradle collects samples beginning with the sensor that has the shortest collection time requirement.
You do not have to reconnect the Lab Cradle to the same computer or handheld to download the data. You can use any computer or handheld running a compatible OS and TI-Nspire™ software to download the data.
About the Lab Cradle
Portability
The Lab Cradle fits into the palm of most high school students' hands when connected to the TI-Nspire™ handheld.
8 TI-Nspire™ Lab Cradle
The Lab Cradle features an attachment point for a lanyard. Students can attach a lanyard to wear the Lab Cradle around their neck. This feature lets students keep their hands free to steady themselves in rough terrain during remote data collection activities.
When collecting data for an experiment that subjects the Lab Cradle to intense movement, TI recommends that students wear a Vernier Data Vest or zip-up jacket with the sensor secured both around the student’s neck as well as to the student’s chest. For example, if a student is measuring speed or motion on a roller coaster, the Lab Cradle may bounce around due to the movement of the roller coaster. Wearing a zip-up jacket or Vernier Data Vest limits the movement of the Lab Cradle.
Durability
The Lab Cradle is durable enough to withstand extensive use in the classroom and in the field. It is designed to survive being dropped from a height of 36 inches, the height of a standard lab table.
Storing/Operating Temperature Ranges
The Lab Cradle storage temperature range is between -40°C (-40° F) to 70°C
(158° F).
The Lab Cradle, when used as a stand-alone data collection tool, operates in temperatures from 10° C (50° F) to 45° C (113° F).
Triggering Methods
The Lab Cradle has two options for triggering data collection—automatic or manual.
To use automatic triggering, define the criteria in the Vernier DataQuest™ application to start data collection. The Lab Cradle can trigger on either an increasing or decreasing value.
Manual triggering is defined in the Vernier DataQuest™ app. By setting the trigger delay value to zero, you can start data collection by pressing the trigger button on the Lab Cradle when using it as a stand-alone data collection tool.
You can define a delay in triggering the data collection when using the Lab
Cradle with a computer or handheld. The Vernier DataQuest™ app starts a countdown based on the time delay you define. When the countdown reaches zero, the Lab Cradle and its connected sensors begin collecting data.
TI-Nspire™ Lab Cradle 9
Multi-Channel Data Collection
You can connect up to five sensors to the Lab Cradle. It provides three analog
BT connectors and two digital BT connectors.
The Lab Cradle supports multi-channel data collection by allowing you to collect data through all five sensors at the same time. When using all five sensors at the same time, the time stamp is the same for all data collection streams.
Sampling Rate
The maximum sampling rate for a Lab Cradle using a single BT sensor is
100,000 samples per second. This sampling rate allows you to collect data for high-sample sensors, such as microphones, blood pressure monitors, and hand-grip heart rate monitors.
If using more than one sensor at the same time, the 100,000 samples per second rate is divided by the number of connected sensors. For example, when using:
• One sensor, data is collected at 100,000.
• Two sensors, data is collected at 50 kHz per sensor.
• Three sensors, data is collected at 33.3 kHz per sensor.
Some sensor’s maximum sample rates are less than the maximum sample rate of the Lab Cradle. For example, with five sensors connected to the Lab Cradle, data may be collected at 20 kHz per sensor; however, temperature sensors may only be capable of collecting data at 1 kHz so it will only collect data at that rate.
Viewing Data Collection Status
The Lab Cradle has an LED light located on the top to indicate data collection status. This light will be red, green, or amber and use a variety of blink patterns.
TOP
Data collection activity status
10 TI-Nspire™ Lab Cradle
Red
• Red indicates that you need to wait until the system is ready.
• Slow blink: The Lab Cradle is updating experiment storage space. This is automatic behavior and does not impact active collections.
• Fast blink: Indicates one or more attached sensors are not warmed up.
(You may still collect data during the warm-up period but you risk the data being less precise.)
Amber
• Amber indicates the system is ready but the collection has not yet started.
•
One blink per second: The sensor is configured and set up for sampling.
• Slow blink: The Lab Cradle is connected to a computer or handheld running TI-Nspire™ software but not set up for sampling.
• Fast blink: The Lab Cradle is ready for data collection when you press the trigger.
Green
• Green indicates the system is actively collecting data.
• Slow blink: Actively collecting data.
Note:
There may be a slight variation in the duration of the blink depending on the mode/rate of collection.
• Fast blink: Pre-storing data prior to a trigger.
Alternating Amber and Green
• The blinking pattern indicates the system is in trigger mode but has not yet reached the trigger event.
Managing Power
When managing the power for the Lab Cradle, you must consider the power source being used. The Lab Cradle can be powered by its rechargeable battery or a connected power cord.
Batteries
The Lab Cradle runs on a rechargeable battery that supports one full day of high-use, high-consumption sensor data collection before recharging. An example of high-use data collection is an experiment requiring 150 total
TI-Nspire™ Lab Cradle 11
minutes of continuous data collection with CO2 (47 mA) and O2 sensors at one sample every 15 seconds.
The battery recharges in less than 12 hours.
Viewing the Battery Status
There are two ways to view battery status: when attached to a handheld, or by looking at the LED light. When the Lab Cradle is attached to a TI-Nspire™ handheld, you can view the battery status for both. The first value is the handheld and the second value is the Lab Cradle.

When in the TI-Nspire™ Cradle Charging Bay:
• Red - Solid LED indicates the charge is low but is still charging.
• Amber - Solid LED indicates the Lab Cradle is charging.
12 TI-Nspire™ Lab Cradle
• Green - Solid LED indicates the Lab Cradle is fully charged.
When running and not charging:
• Red - Blinking LED indicates the battery is below six percent.
• Amber - Blinking LED indicates the battery is below 30 percent.
• Green - Blinking LED indicates the battery is between 30 percent and 96 percent. Two green blinks per second indicates the battery is over 96 percent.
Managing Battery Power
When the battery power reaches 30 percent, a yellow LED indicates the Lab
Cradle needs to be charged. The LED turns red when the battery power reaches five percent.
When managing battery power for the Lab Cradle, remember that some sensors need to warm up before use. You can collect data while the sensor is warming up; however, the data may not be as precise.
When you start a long-term or remote data collection, the system checks current power sources to determine if the sources are adequate to support the sensors from the beginning to the end of the experiment.
If the power is unable to support the experiment configuration, a warning indicates that the power available is insufficient for the experiment. You either need to charge the battery or plug the Lab Cradle into an external power source.
When using the wall charger, TI-Nspire™ Cradle Charging Bay, or USB cable plugged into a powered computer, the Lab Cradle can be fully charged from a dead state in less than 12 hours when not being used.
The battery is capable of supporting one full day of high-use, high-consumption sensor data collection or two full days of moderate to low consumption sensor data collection.
Charging the Lab Cradle
You can charge the Lab Cradle in a number of ways.
• Wall charger
• USB Cable connected to a computer
• TI-Nspire™ Navigator™ Cradle Charging Bay
