4. Direct connection by emulated serialization on parallel DIO
1. Direct connection from SI n ( ) to DO n ( )
Serial port input can be directly connected to parallel port output. The relation of the
parallel port and serial port that can be connected is as follows.
Output device such as sensor

identical with the port used by the
program, the output results might be
inaccurate.
