USER'S GUIDE
JY992D48801B

●The FX-232ADP type RS232C adapter (hereinafter called 232ADP)
is connected to the FX(V3.07 or later),FX2C series PC to exchange serial
data with a personal computer, barcode reader, printer, and other various
RS232C devices.
●Only one 232ADP unit can be connected to one base unit to the serial
port provided at the left side.
●The buffer size and location are specified by an RS instruction in the PC.
●This product cannot be combined with special adapters such as
FX-8AV,FX2-40AP/AW, or the lide.

●For data transmission to be effective it is necessary to match the communication format between the product and the
RS232C device, such as baud rate and parity.
*1 The default value is STX (02H: changeable).
*2 The default value is ETX (03H: changeable).
●The communication format is set by special data register D8120.
Setting the communication format using D8120 is effective only at the time the RS instruction is driven, and therefore
if changed after driving, it is not actually accepted.
●An example of setting D8120 is shown below.
●The control line is set by b12.
b12=0 :No hardware hand shaking.Send and receive are controlled by software protocol.
b12=1 :Hardware hand shaking.Signal lines ER(DTR)and DR(DSR)are used to control send and receive of data.
H138F= 0001 0011 1000 1111(binary)

and switch the PC to RUN.
Turn on X000, and drive RS
instruction.
Every time X001 is turned on, the
contents of D200 to D210 are
sent to the printer, and
"test line" is printed.
●In this example, CR (H000D) and LF
(H000A) are written at the end of the
message.The printer moves down
one line for each message.
CR: Carriage Return
LF: Line Feed
Note:It may be necessary to set the
DIP switches of your printer.
Check your printer manual for how to
configure the serial communications.

DIAGNOSTICS
●If sending and receiving using these programs is
successful, it is considered that the operation failure
was due to sequence program or communication
protocol error.
●Program when receiving
●If data transfer does not perform correctly when using
the 232ADP, check the operation using the following
programs.
●Program when sending
* Write the data to be sent to D 0 to D 19 before operating.
