Example 2: Performing Signal Control
When CIO 000001 and the RS-232C port’s Send Ready Flag (A39205) are
ON in the following example, the RS signal is set according to the status of
D00300 bit 15 and the ER signal is set according to the status of D00300 bit
14.

Example 3: Sending Data to a Code Reader
This example shows how to send data to the V530-R150V3 2D Code Reader
as an example of communicating with an external device.
Hardware Configuration
In this example, the external device is connected to the RS-232C port built
into the CPU Unit.
First, set the reading conditions for the Code Reader.
