Introduction
STPiXA3306 series is provided with compliant serial RS232/RS485 interface. Prepare the user
application according to this protocol procedure. Operation instructions and information, such as the
running state and setting values of the STP pump can be set by the software.
The STP pump equips the serial ports for connecting the user application, STP-Link (optional
accessory), or the display unit iDT-001 (optional accessory). (see Figure 40)
The STP pump is equipped with 3 serial ports COM1, COM2 and STP-Link as a standard.
A serial port located the STP pump is called a serial interface module (hereafter referred to as SIM).
The equipment, which can communicate with the STP pump via RS232/RS485, is called a PC.
