Data Communications
This chapter tells you everything you need to know to transfer
programs between two CASIO Power Graphic calculators
connected using the cable that is equipped as a standard
accessory.
You can also use the cable to connect the calculator to a CASIO
Label Printer to print screen data.
To transfer data between a calculator and a personal computer,
you need to purchase the separately available CASIO FA-123
Connection Kit.

to print screen shot data from the unit (see 10-6 Sending a Screen Shot). See the user’s
guide that comes with your Label Printer for details on how to perform this operation.
•The operation described above can be performed using the following Label Printer
models: KL-2000, KL-2700, KL-8200, KL-8700 (as of February 1999).
uTo connect the unit to a Label Printer
1. Check to make sure that the power of the unit and the Label Printer is off.
2. Connect the cable to the Label Printer.
3. Remove the cover from the connector of the unit.
4. Connect the other end of the cable to the unit.
5. Turn on the power of the unit, followed by the Label Printer.
•After you finish data communications, turn off power in the sequence: the unit first, and
then the Label Printer. Finally, disconnect the equipment.

After inputting the password, press w.
Note the following precautions whenever you perform data communications.
•An error occurs whenever you try to send data to a receiving unit that is not yet standing
by to receive data. When this happens, press ito clear the error and try again, after
setting up the receiving unit to receive data.
•An error occurs whenever the receiving unit does not receive any data approximately six
minutes after it is set up to receive data. When this happens, press ito clear the error.
•An error occurs during data communications if the cable becomes disconnected, if the
parameters of the two units do not match, or if any other communications problem
occurs. When this happens, press ito clear the error, then correct the problem before
trying data communications again. If data communications are interrupted by the ikey
operation or an error, any data successfully received up to the interruption will be in the
memory of the receiving unit.
•An error occurs if the receiving unit memory becomes full during data communications.
When this happens, press ito clear the error and delete unneeded data from the
receiving unit to make room for the new data, and then try again.
•The E-CON item contains the following data.
1. Current Setup Data
2. Setup Memory Data
3. Custom Probe Memory Data
The corresponding data is overwritten on the receiver. Setup Memory data and Custom
Probe Memory data overwrites the data for the same memory number on the receiver. If
you want to keep data from being overwritten on the receiver, change its memory number.

MEMORY Mode
10-8 MEMORY Mode
This calculator has two separate memory areas: a “current area” and a “storage area.” The
current area is a work area where you can perform input data, perform calculations and run
programs. Data in the current area is relatively safe, but it can be deleted when batteries go
dead or when you perform a full reset.
The storage area uses “flash memory,” so data is safe even when power is interrupted.
Normally, you would use the storage area for data you need to store securely for long periods
and load it into the current area only when you need it.
Use the MEMORY Mode to transfer data between the current area and storage area, and to
perform other memory management operations.
From the Main Menu, select the MEMORY icon to enter the MEMORY Mode and display its
initial screen.
