Communication
4. Direct connection by emulated serialization on parallel D
2. Direct connection from SO n ( ) to DI n ( )
Parallel port input can be directly connected to serial port output. The relation of the
parallel port and serial port that can be connected is as follows.
Input device such as valve
DI port
SO port
→
DI2() SO2()
DI3() SO3()
DI4() SO4()
DI5() SO5()
[Operation]
1. Select a DI port (from items 5 to 8) in the “SYSTEM > OPTION > SIO” mode.
2. Press the
F 1
(EDIT) key.
SYSTEM>OPTION>SIO V8.01
5.Direct SO2() <- DI2() NO
6.Direct SO3() <- DI3() NO
7.Direct SO4() <- DI4() NO
8.Direct SO5() <- DI5() NO
SET NO
4.Direct SI5() -> DO15() NO
3. Press the
F 1
(SET) key to enable the connection or the
F 2
(NO) key to
cancel the setting.
4. Press the
ESC
key to quit setting or select another DI port with the cursor keys to
continue setting.

NOTE
When the port specified by SIO is
identical with the port used by the
program, the output results might be
inaccurate.
