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.

Connecting the Unit with a CASIO Label Printer
10-2 Connecting the Unit with a CASIO Label
Printer
After you connect the unit to a CASIO Label Printer with cable, you can use the Label Printer
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.

10-3 Connecting the Unit to a Personal
Computer
To transfer data and screen shots between the unit and a personal computer, you must
connect them through a separately available CASIO FA-123 Connection Kit.
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-123.
Some types of data may not be able to be exchanged with a personal computer.
uTo connect the unit to 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-123 Connection Kit.
3. Remove the cover from the connector of the unit.
4. Connect the unit to the FA-123 Connection Kit.
5. Turn on the power of the unit, followed by the personal computer.

Connecting the Unit to a Personal Computer
#The ALGEBRA calculator also supports to PC
transfer of programs created with a CASIO
CFX-9850 Series calculator.
#Be sure you keep the connector cover in a safe
place so you can replace it after you finish your
data communications.
•After you finish data communications, turn off power in the sequence: the unit first, and

kPerforming a Data Transfer Operation
Connect the two units and then perform the following procedures.
Receiving unit
To set up the calculator to receive data, press 2(Recv) while the data communication main
menu is displayed.
The calculator enters a data receive standby mode and waits for data to arrive. Actual data
receive starts as soon as data is sent from the sending unit.

Sending unit
To set up the calculator to send data, press 1(TRNS) while the data communication main
menu is displayed.
Press the number key that corresponds to the type of data you want to send.
• {Select} ... {selects data items and sends them}
• {Currnt } ... {selects data items from among previously selected data items and sends
them}
• {Backup} ... {sends all memory contents, including mode settings}
• {H-Copy} ... {selects H-Copy screen shot data and sends it}
uTo send selected data items
Press b(Select) or c(Currnt) to display a data item selection screen.
• {Sel} ... {selects data item where cursor is located}
• {All} ... {selects all data}
• {Trn s } ... {sends selected data items}
Use the fand ccursor keys to move the cursor to the data item you want to select and
press 1(Sel) to select it. Currently selected data items are marked with “'”. Pressing
6(Trns) sends all the selected data items.
•To deselect a data item, move the cursor to it and press 1(Sel) again.
Only items that contain data appear on the data item selection screen. If there are too many
data items to fit on a single screen, the list scrolls when you move the cursor to the bottom
line of the items on the screen.

#Data can become corrupted, necessitating a
RESET of the receiving unit, should the
connecting cable become disconnected during
data transfer.
Make sure that the cable is securely connected to
both units before performing any data communi-
cation operation.

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.
