This technical reference is intended for CBL 2 users who want to write their own
programs for CBL 2 and Texas Instruments graphing calculators. This document includes
technical data such as specifications for sensors, syntax for CBL 2 commands, sample
programs, error codes, and miscellaneous other topics.
Instructions for using CBL 2 with the DataMate program or app are given in Getting
Started with CBL 2, which is included in the CBL 2 package. The DataMate program is
not addressed in this technical reference except for Appendix C: DataMate Sensor
Setup Default Settings. This table shows the default sensor settings and calibrations
used by the DataMate program.

CBL 2 Software Upgrades
The CBL 2 uses FLASH technology, which allows you to easily upgrade to new software
without buying a new CBL 2. As new functionality becomes available, you can
download the software from the TI web site to your PC and then use the TI-GRAPH
LINKé (sold separately) to upgrade your CBL 2.
Check the TI website (
compatibility statements. Directions for downloading upgrades will be given on the
web site.
Data Collection Modes
On the CBL 2, data can be collected in one of three modes: realtime, non-realtime or
FastMode.
In realtime data collection, the CBL 2 collects data and sends it to the calculator
after each point is taken.
In non-realtime data collection, the CBL 2 collects data and stores it internally until
all of the data points are taken and then sends it to the calculator.
In FastMode data collection, the CBL 2 collects data on a single analog channel at a
very fast sample rate, stores it internally until all of the data points are taken, and
then sends it to the calculator.
It is the default to return the time with the data collected.
