INTRODUCTION

The FX0N-232ADP type RS232C adapter (hereinafter called 232ADP) is connected to the FX0N 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.

PROGRAM EXAMPLES

Connecting 232ADP and a printer,and printing out the data sent from the PC.
Printer
FX0N series sequencer
Send
• Receive data
The communication format of the serial printer is as follows.
Data length 8 bit
Parity Even
Stop bit 2 bit
Baud rate 2400bps
• Send data
Sequence program
Common pin out for printer communication
Operation
Power on
X000,ON
RS instruction drive
X001,ON
Data send
Turn on the power of the PC and printer, check the printer is on line 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.
Connect 232ADP and a personal computer,and exchange data with the PC.

Preparation of software
Use ordinary communication software (terminal emulator) or dedicated program in the personal computer.
The communication format of the PC for this example is as follows.

Stop bit 1 bit
Baud rate 2400
If the communication format of the software cannot be adjusted to this setting, adjust the PC and the software to be the same.

Turn on X000, and drive RS instruction.
Every time X001 is turned on, the contents of D200 to D210 are sent to the personal computer, and "test data" is displayed.
After receiving and storing data from personal computer in D211, it is output to Y000 to Y017. When input X002 is turned on, the receive completion flag is reset.

DIAGNOSTICS

If data transfer does not perform correctly when using the 232ADP, check the operation using the following programs.
Program when sending

unintelligible?
NO
Normal
• Match the communication format.
• Check the timing of control line.
