Communications Processing Flow

In a system configuration in which it is connected by Serial (RS-232C) communications to an external
device (such as PLC), serial commands can be received and code reading results can be output to the
external device.
Below is the basic flow for establishing the Serial (RS-232C) communications, executing a Read com-
mand and outputting the Read result.

RS-232C Wiring

There are two ways of wiring the V430-F for RS-232C connection.
Using the RS-232C-I/O 2 Pronge cable (V430-W2-3M)
The D-Sub 9 Pin connector can be connected directly to an IBM PC compatible Serial Port.
