Operation
9 Serial Communication Protocol
9.1 Serial Communication
The STP-iX455/iXL455 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 9.1).
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.
