5.1  Introduction 
STP-iS2207  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 34) 
The STP pump is equipped with 2 serial ports COM1 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.
