5.2.4 Input operation port setting
Set the input operation port to the serial port when operating the STP pump via the serial port in
accordance with the following procedures.
1. Open the "PORT SELECT IN" signal between (1)–(4) of the "X2 REMOTE" connector.
If the pins are closed, the input operation port will be set to the parallel port automatically, and the
input operation via the serial port is disabled (refer to Section 4.9, "Parallel port input/output
signal" for the details of the "X2 REMOTE" connector).
2. Set the parameter of the "Input operation port" to the serial port which operates STP pump,
following Section 5.4.16. The parameter value of the factory setting is "I/O REMOTE" (parallel
port). The "Input Operation Port" can also be changed via the STP-Link (optional accessory).
