October 21, 1999 Texas Instruments announced the Second Generation Calculator-Based
Laboratory™ or CBL 2™ and introduced it about March 2000 in the United
States, Canada, Europe, Australia and Latin America.
Main differences between the CBL 2 and
predecessor CBL are the introduction of the Flash
technology as program and data memory and the missing LC-display for convenient
The CBL 2 connects to a graphing calculators such as the TI-73, TI-73 Explorer, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, TI-85, TI-86, TI-89, TI-89 Titanium, TI-92, TI-92 Plus and Voyage 200. New features include Flash memory with built-in calculator software, a supporting cradle, and four channels for data collection. The Flash memory allows users to update programs with the most current software version and update the functionality of the CBL 2. Users can utilize the remaining memory to store multiple experiment trials, experiment setups or other programs. The Innovative Cradle System allows the CBL 2 and graphing calculator to become one unit for portable single-handed use on most Texas Instruments graphing calculators.
Additional features include the following:
|• Built-in User Program: Transfer programs
to calculators with
the push of a single button. Start collecting data immediately,
or set up the CBL 2 for more sophisticated applications.
• Quick Setup Mode: Collect data without the calculator using
auto-identification (Auto-ID) sensors. Reconnect to a calculator
or computer to retrieve and analyze the data.
The included Auto-ID sensors are light, voltage and a new and
improved stainless steel temperature sensor.
• Compatibility: Compatible with most existing CBL programs and
workbooks as well as with many popular sensors for data collection.
• Language Localization: Download one of more than 10 language
versions of the built-in user program, including Spanish, French,
Italian, Swedish and Portuguese.
• Performance: Collect a total of approximately 12,000 data points
at rates of up to 10,000 points per second on each analog channel
or up to 50,000 points per second on a single analog channel.
Users can start collecting data immediately with the CBL 2
with four easy steps:
|• Transfer the built-in DataMate user program from the CBL 2
the calculator with a single button push.
• Run the DataMate program (DataMate application on the TI-83 Plus).
• Plug an Auto-ID sensor into the CBL 2.
• Begin collecting data.
The hardware of the CBL 2 System makes use of a powerful Toshiba TMP91CW12F microcontroller with fast 10-bit Analog-Digital converters, a 32k Bytes Static RAM and 1M Bytes of Flash ROM. The brain of the CBL 2 is a member of the TLCS-90 family, actually a 16-bit implementation of the Zilog Z80 CPU with 4k Byte RAM and 128k Byte ROM plus a lot of peripherals integrated into a tiny package.
The CBL 2 system accepts three analog inputs
and an ultrasonic motion detector input to connect the Calculator-Based Ranger CBR
and its successor CBR 2. The sampling rate is adjustable between 10,000 samples per second to one sample
every 4 hours on each analog channel or up to 50,000 samples per second on a single
analog channel. The memory stores a maximum of 12,000 datapoints compared
to the 512 points per channel of the original CBL System.
The CBL 2 has approximately 500K Bytes of free memory that allows users to save experiment setups, store multiple trials and archive other calculator programs. The addition of Flash memory gives users the ability to upgrade the functionality of the unit instead of having to purchase a new one. To that end, the Flash technology allows the CBL 2 to grow with educators' changing curriculum because they can download software upgrades from the TI Web site.
The CBL 2 being marketed by Texas Instruments was developed as part of an ongoing business alliance between TI and Vernier Software of Portland, Oregon.
The TI-Nspire and
TI-Nspire CX calculators are compatible with the
TI-Nspire Lab Cradle introduced in 2011.
