15. Communication RS232
The OPCom Particle Monitor has a serial interface, via which it can be read out and configured.
For this purpose, a PC and an appropriate terminal program or a readout software is needed. The sensor has to be connected to a
free COM port of a computer. A suitable communication cable for serial connection between sensor and computer / controller is
described in Chapter 21 "Accessories". If the computer does not have a serial COM port, it is possible to use a USB-serial converter.
