Solution 10391: Linking a TI-83 Family or TI-84 Plus Family Graphing Calculator to a TI-82 Graphing Calculator.

What Can Be Transferred Between a TI-83 Family or TI-84 Plus Family Graphing Calculator And a TI-82 Graphing Calculator Linked Together?

All variables and programs are transferable from a TI-82 to both the TI-83 family and TI-84 Plus family calculators by linking them together with a unit-unit cable.  Also, real lists L₁ through L₆ with up to 99 elements can be transferred from a TI-83 family / TI-84 Plus family calculator to a TI-82 using the Lists to TI82... command in the LINK Send menu.  The software that enables this communication is built into the TI-83 family / TI-84 Plus family calculator.  

The only data type that can be transmitted from a TI-83 family / TI-84 Plus family calculator to a TI-82 is real list data stored in L₁ through L₆ with up to 99 elements for each list.  To transmit to a TI-82 the list data that is stored to a TI-83 family / TI-84 Plus family calculator lists L₁, L₂, L₃, L₄, L₅, or L₆, follow these steps:

• On the TI-82, press [2nd] [LINK] [Þ] [ENTER] to set it to receive - The message Waiting... and the busy indicator are displayed.
• On the TI-83 family / TI-84 Plus family calculator, press [2nd] [LINK] [5] to select 5:Lists to TI82. - The SELECT screen is displayed.
• Select each list to transmit by pressing [ENTER] on each one
• Press [Þ] to display the LINK TRANSMIT menu 
• Confirm that the receiving unit is set to receive
• Press [ENTER] to select 1:Transmit and begin transmitting.

Please Note: If dimension > 99 for a TI-83 family / TI-84 Plus family list that is selected to send, the receiving TI-82 will truncate the list at the ninety-ninth element during transmission.

Resolved differences between the TI-82 and the TI-83 family / TI-84 Plus family calculators:

Generally, items can be transmitted to a TI-83 family / TI-84 Plus family calculator from a TI-82, but differences between the two products may affect some transmitted data.  This table shows differences for which the software built into the TI-83 family / TI-84 Plus family calculator automatically adjusts when it receives TI-82 data:

For example, if a program that contains nStart on a command line is transmitted from a TI-82 to a TI-83 family / TI-84 Plus family calculator, and then the program is displayed on the receiving unit, nMin will have replaced nStart on the command line.

Unresolved differences between the TI-82 and the TI-83 family / TI-84 Plus family calculators:

The software built into the TI-83 family and TI-84 Plus family calculator cannot resolve some differences with the TI-82, which are described below.  The data must be edited on the TI-83 family / TI-84 Plus family calculator after transmission to account for these differences, or the TI-83 family / TI-84 Plus family calculator will misinterpret the data. 

The TI-83 family / TI-84 Plus family calculator reinterprets the TI-82 prefix functions to include open parentheses, which may add extraneous parentheses to transmitted expressions.

For example, if sin X+5 is transmitted from a TI-82 to a TI-83 family / TI-84 Plus family calculator, the receiving unit reinterprets it as sin(X+5.  Without a closing parentheses after X, the receiving unit interprets this as sin(X+5), not the sum of 5 and sin(X).  If a TI-82 instruction that the TI-83 family / TI-84 Plus family calculator cannot translate is transmitted, the ERR:INVALID menu is displayed when the receiving unit attempts to execute the instruction.  For example, on the TI-82, the character group U_n-1 is pasted to the cursor location when [2nd] [U_n-1] is pressed.  The TI-83 family / TI-84 Plus family calculator cannot directly translate U_n-1 is to its syntax u(n-1), so the ERR:INVALID menu is displayed.

Please Note: Implied multiplication rules of the TI-83 family / TI-84 Plus family calculator differ from those of the TI-82.  For example, the TI-83 family / TI-84 Plus family calculator evaluates 1/2X as (1/2)*X, while the TI-82 evaluates 1/2X as 1/(2*X).
