This manual contains text,diagrams and explanations which will guide the reader in the correct installation and operation of the FX0N-232ADP and should be read and understood before attempting to install or use the unit. Further information can be found in the FX SERIES PROGRAMMING MANUAL and FX0/FX0N HARDWARE MANUAL.

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.

●

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.

Communication format D8120 (bit mapping)

Bit Description 0(OFF) 1(ON)

b 0 Data length 7bit 8bit

b 1 b 2

b 3 Stop 1bit 2bit

b 4 b 5 b 6 b 7

●

The communication format is set by special data register D8120.
