4. DATA COMMUNICATIONS

■ General Procedure

The following is the general procedure to follow when performing data communications. Details of each
procedures are presented in the following sections of this chapter.

• Though you can transfer data between the fx-7700GE and another fx-7700GE, an fx-7700GB or an fx­8700GB, all of the examples in this manual cover data transfer with another fx-7700GE only.

1. Connect the two units.

2. Set up the two units with the same parameters.

3. Set up one unit to send, and the other unit to receive.

4. On the receive unit, specify the data to be received and put the unit into receive standby.

5. On the send unit, specify the data to be sent and start the send operation.

4-1. CONNECTING TWO fx-7700GE UNITS

The following procedure describes how to connect two Power Graphic units with an optional SB-62 connecting
cable for transfer of programs between them.

■ To Connect Two fx-7700GE Units

1. Check to make sure that the power of both fx-7700GE units is off.

2. Remove the covers from the connectors of the two Power Graphic units.

• Be sure you keep the connector covers in a safe place so you can replace them after you finish your

program communications.

3. Connect the two units using the SB-62 cable.

Important

• Keep the connectors of the fx-7700GE covered when you are not using them.

Note

• If the selections you make on the send unit and receive unit do not match, a TRANSMIT ERROR will be
generated on the sender and a RECEIVE ERROR will be generated on the receiver.

4-3. SETTING COMMUNICATIONS PARAMETERS

Before you can perform data communications, you must first set up cartain hardware parameters to make sure
that the two units are able to understand each other. The parameters of the sender and the receiver must be
identical for them to be able to communicate correctly. There are two hardware parameters that you can set.

4-4. USING ALL TO SEND ALL DATA

The following procedures show how to send all data, from Program to Equation from one fx-7700GE unit
to another.

•Warning!

The following operation causes data in the seven applicable memory areas (program, function memory,
matrix memory, single-variable and paired-variable statistical data memory, value and extended
mempry, graph function memory, and equation coefficient memory) of the receiving unit to be replaced
by the received by the received data. Make sure that you do not need the data stored in the receiving
unit before you start this operation.

4-6. DATA COMMUNICATIONS PRECAUTIONS

Note the following precautions whenever you perform data communications.

• A TRANSMIT 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 AC to clear the error and try again, after setting up the receiving
unit to receive data.

• A RECEIVE 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 AC to clear the error.

• A TRANSMIT ERROR or RECEIVE 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 AC to clear the error and correct the problem before trying data
communications again. In this case, any data received before the problem occurred is cleared from the
receiving unit's memory.

• A MEMORY FULL operation occurs if the receiving unit memory becomes full during data communications.
When this happens, press AC to clear the error and delete unneeded data from the receiving unit to make
room for the new data, and then try again.
