The ID list feature provides a convenient way to collect calculator
IDs for group purchase of commercial applications. After the IDs are
collected, transmit them to Texas Instruments so a group certificate
can be issued.
A group certificate allows distribution of purchased software to
multiple
TI -89 / TI-92 Plus units. The software can be loaded, deleted
from, and reloaded to the calculators as often as needed for as long
as the software remains listed in the group certificate. You may add
new ID numbers and/or new commercial applications to a group
certificate.
You can use one calculator to collect all of the IDs, or use several
collection units and then consolidate their ID lists onto one
calculator.
To send an ID number from one calculator to another, first connect
two units by using the calculator-to-calculator cable that came with
the
TI -89 / TI-92 Plus . Refer to the illustrations on page 366.
