When the CBL 2's base code detects an error in the commands sent from the host, a
high-high beep sounds twice.
When the CBL 2 powers up:
two high-high beeps sound if the base code is not loaded.
three high-high beeps sound if the power-up self-test fails.
During base code download, three high-high beeps sound when any errors occur.
(The unit resets and then the two high-high beeps mentioned in the previous bullet
sound.)
Archiving in CBL 2's FLASH Memory
The FLASH memory in the CBL 2 can be used for several purposes. In addition to
allowing updates to the operating system and storing the DataMate programs, the
FLASH memory serves as an archive space for other programs and data.
To preserve collected data so that it can be retrieved at a later time, data sets can be
stored in the FLASH archive. To distinguish between different stored data sets, each
data set can be given a name.
You can write a program on the calculator to review the list of stored data sets and
retrieve the desired one for further analysis. (See the sample archive program on
page 56.)
You can use the DATADIR program (available on the TI Resource CD or on the TI
web site at
www.ti.com/calc
DATADIR program are given in Getting Started with CBL 2.
The FLASH archive can also store calculator programs and applications. This provides a
convenient location for storing frequently used programs or as a temporary storage to
create more available memory on the calculator.
Command 201, in conjunction with the Link menu on the calculator, provides access to
these FLASH archive operations. For details about Command 201, see page 44.
