Data Communications
This chapter tells you everything you need to know to transfer
programs between the CASIO Power Graphic unit and another
CASIO Power Graphic unit, connected with an optionally avail-
able SB-62 cable. To transfer data between a unit and a personal
computer, you will need to purchase the separately available
CASIO FA-123 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.

62 connecting cable for transfer of programs between them.
uu
uu
uTo connect two units
1. Check to make sure that the power of both units is off.
2. Remove the covers from the connectors of the two units.
•Be sure you keep the connector covers in a safe place so you can replace
them after you finish your data communications.
3. Connect the two units using the SB-62 cable.

21-2 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-123 connection cable.
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.

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 commu-
nication 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(TRAN) while the data communi-
cation main menu is displayed.
Press the function key that corresponds to the type of data you want to send.
• {SEL} ... {selects data items and sends them}
• {CRNT} ... {selects data items from among previously selected data items and
sends them}
• {BACK} ... {all memory contents, including mode settings}
uu

• {TRAN} ... {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(TRAN) 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.
The following types of data items can be sent.

You cannot send the following types of screens to a computer.
•The screen that appears while a data communication operation is in progress.
•Ascreen that appears while a calculation is in progress.
•The screen that appears following the reset operation.
•The low battery message.
•The flashing cursor is not included in the screen image that is sent from the
unit.
•If you send a screen shot of any of the screens that appear during the data
send operation, you will not be able to then use the sent screen to proceed
with the data send operation. You must exit the data send operation that
produced the screen you sent and restart the send operation before you can

21-7 Data Communications Precautions
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 Ato 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 approxi-
mately six minutes after it is set up to receive data. When this happens, press A
to 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 Ato clear the error and correct the
problem before trying data communications again. If data communications are
interrupted by Akey operation or an error, any data successfully received up
the interruption will be in the memory of the receiving unit.
•An error occurs if the receiving unit memory becomes full during data communi-
cations. When this happens, press Ato clear the error and delete unneeded
data from the receiving unit to make room for the new data, and then try again.
•To send picture (graph) memory data, the receiving unit need 1-kbytes of memory
for use as a work area in addition to the data being received.
