Data Communications
This chapter tells you everything you need to know to transfer pro-
grams between the fx-9750G and certain CASIO Graphic Scientific
Calculator models connected with an optionally available SB-62
cable. To transfer data between a unit and a personal computer,
you will need to purchase the separately available CASIO FA-122
Interface Unit.
This chapter also contains information on how to use the optional
SB-62 cable to connect to a CASIO Label Printer to transfer screen
data for printing.

20-2 Connecting the Unit with a Personal
Computer
To transfer data between the unit and a personal computer, you must connect them
through a separately available CASIO FA-122 Interface Unit.
For details on operation, the types of computer that can be connected, and hardware
limitations, see the user’s manual that comes with the FA-122.

uTo connect the unit with a personal computer
1. Check to make sure that the power of the unit and the personal computer is off.
2. Connect the personal computer to the FA-122 Interface Unit.
3. Remove the cover from the connector of the unit.
• Be sure you keep the connector cover in a safe place so you can replace it after
you finish your data communications.
4. Connect the unit to the FA-122 Interface Unit.
5. Switch on the power of the unit, followed by the personal computer.

20-3 Connecting the Unit with a CASIO Label
Printer
After you connect the unit to a CASIO Label Printer with an optional SB-62 cable,
you can use the Label Printer to print screen shot data from the unit. See the User’s
Manual that comes with your Label Printer for details on how to perform this opera-
tion.
• The operation described above can be performed using the following Label Printer
models: KL-2000, KL-2700, KL-8200 (as of October 1996).
