INTRODUCTION

●

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.

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.

DIAGNOSTICS

●

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

●
