TI-73
Link Capabilities
The TIN73 comes with a unit-to-unit link cable. With this cable,
you can connect to and communicate with another TIN73, a
TIN82, a TIN83, the Calculator-Based Laboratory™ (CBL 2™,
CBL™), or the Calculator-Based Rangerè (CBRè). You can
communicate with a personal computer using TI™ Connect or
TI-GRAPH LINK™ software and a TI-GRAPH LINK cable.
For information about any of these accessories, contact Texas
Instruments Customer Support (see Appendix C:
BatteryàService and Warranty Information).
To connect the TIN73 to another device using the unit-to-unit
cable, use the link port located at the center of the bottom
edge of the calculator.
1. Insert either end of the unit-to-unit cable into the TIN73
port very firmly.
2. Insert the other end of the cable into the port of the other
device.

Linking to Another Calculator

By linking two TI-73’s you can transfer all variables and
programs to another TIN73 or back up the entire RAM
(Random Access Memory) of a TIN73. To transmit from one
TIN73 to another, you first must set up one TIN73 to send and
the other to receive using the 9 1:Link SEND and RECEIVE
menus (see page 255 and 257).
Linking a TIN73 to a TIN82 or TIN83 lets you transfer some
types of data between the calculators. Use the 9 1:Link
SEND menu items 9:Vars to TI82 and 0:Vars to TI83 (see page 256).
• You can only transfer numerical list data stored in L1–L6
(NOT categorical lists) to a TIN82. All fractional elements
are converted to decimals.
If dimension>99 for a TIN73 list that is selected to be sent
to a TIN82, the TIN82 truncates the list at the 99th element
during transmission.
