5. TO SAVE THE DATA TO OTHER MACHINE
CASIO's SB-62 Data Communication Cable is available as an option. You can use this to connect My Magic
Diary to another My Magic Diary unit, or to a CASIO SF-A10, SF-A20, or SF-A30. Data can be shared among
all of these products.
Basic hardware set up for data communication:
1. Switch off the power of both the sending and receiving units.
2. Remove the connector covers of both units.
3. Connect the two units with a CASIO SB-62 Data Communication Cable. Be sure to insert the connectors
at the ends of the cable securely into the units.
4. Switch on the power of both sending and receiving units.
To prepare one unit to receive:
1. On the unit intended for reception, while in the main menu or a data display, press FUNCTION. Then use
to highlight "Communication." Press EXE.
2. Use the or to highlight "Receive Data." Press EXE.
Sending Data for a Specific Mode
You can send either a single data item (the smallest packet of data which can be sent in the Calendar Mode,
for example, is a single month), or all the data items stored in a specific mode. Different procedures are used
to send all the data in a mode, depending on whether you start from within that mode, or from the main menu.
To send one data item:
1. Enter the mode that contains the data; then search for and display the data you wish to send.
2. Press FUNCTION. Then use to highlight "Communication." Press EXE.
3. Use to highlight "Send Data." Press EXE.
4. Use to highlight "1 Data." Press EXE.
5. Use to highlight "Yes." Then press EXE. This begins data transfer to the receiving unit.
To send all the data in a mode, starting from within that mode:
1. Enter the mode that contains the data you want to send. Then press or to display the data for that
mode.
2. Press FUNCTION. Then use to highlight "Communication." Press EXE.
3. Use to highlight "Send Data." Press EXE.
4. Use and to highlight "Mode Data." Press EXE.
5. Use to highlight "Yes." Then press EXE. This begins data transfer to the receiving unit.
6. After the transmission has been completed, the data display for the item sent will appear on screen.

6. Use to highlight "Yes." Then press EXE. This begins data transfer to the receiving unit.
7. After the transmission has been completed, the main menu will reappear.
Sending All Data
Important!
The following procedure sends either all Open Memory Area data or all Secret Memory Area data. Before
starting to transmit, be sure to access the memory area (Open or Secret) which contains data you wish to send.
To send all data:
1. Begin from either the main menu or from a data display (Telephone Directry, Schedule, Data Memo "Diary",

6. After the transmission has been completed, the display you started from will reappear.
About the "Set up" Menu Item
You will probably notice that the menu appears on the display after you select "Communication" from the
function menu and press EXE. The "Set up" item contained in that menu is used for setting the parameters
of the My Magic Diary. Note, that the parameters should always be set to "None" (Parity) and "9600" (BPS)
for data communications between two units.
