Notes:
1 Operand information relating to whatever operation is being performed. (must be integer)
2 Additional information about the operation to be performed.
3 The Calculator Type specifies the model of the calculator on which the user program is running. This
determines which programs in LabPro archive will be shown in the directory information. Available
choices are: 73, 82, 83, 83.1 (for 83 Plus and 83 Plus Silver Edition), 86, 89, 92, and 92.1 (for 92 Plus).
4 The Directory Type specifies the entries in the archive on which to perform the operation. Available
choices are: 0 (Sample Data Set), 1 (Saved List), and 2 (Saved Program).
5 If a directory entry does not have a label assigned to it, LabPro reports the label as
‘????????????????????’.
5,6 Because the TI-82, TI-89, TI-92, and TI-92 Plus do not receive string variables, the program names in
the directory cannot be passed directly as strings. The Numeric List option in operation 3 provides an
indirect way of representing the names. The list contains the ASCII code for each character in the name.
These ASCII codes can be interpreted by the user program to display the correct letters on the calculator.
6 Send a command with Operation 4 to set up label directory entry; then follow it with another command
that contains the label.
7 Built-in user programs: LabPro stores a collection of calculator programs (DataMate) and look-up tables
in its FLASH memory. These programs are intended to simplify the task of data collection and analysis.
Because these programs are designed to work together, they can only be stored and deleted as a group. To
free up memory in LabPro, you can delete the programs for calculators that you do not use.
Upgrading User Programs: The FLASH Download software provides a way to update the user programs
and lookup tables for all calculator platforms. The FLASH Download process automatically deletes all
existing user programs (all calculator models) from the archive. The new look-up tables and programs are
then installed into the archive. (Instructions for downloading new software are given on the TI web site at
www.vernier.com.)
8 Two optional identifying numbers can be used when saving a data set or list. These numbers are saved
with the data in addition to the supplied label.
9 Operations 24, 25, and 26 are provided to facilitate saving configuration information in the same data
structure as a saved experiment, rather than in a separate file.
10 Operation 41 allows you to retrieve programs saved on LabPro. You can save programs to LabPro by
enabling writing {201,0,0,0,2.46802} and then sending programs from the calculator’s LINK/SEND menu.
11 Operation 42 cancels operation 41 or 43. If the TRANSFER key is not pressed within one minute,
operations 41 and 43 cancel automatically.
12 LabPro can store additional built-in programs in the same storage area as DataMate (for example,
programs such as DataDir and DataGate). Because of memory space considerations, these supplemental
programs are normally not transferred to the calculator with DataMate when the TRANSFER key is
pressed. Operation 43 allows you to retrieve these supplemental programs by overriding the normal
operation of the TRANSFER key.
