RS-485 Interface
The read head is equipped with an RS-485 interface for communication purposes, i.e. parame-
terizing the read head functions or reading out current process data during operation. This
interface is operated in 8-E-1 operating mode and is fitted with a terminator that can be acti-
vated or deactivated by parameterizing the sensor head. The RS-485 interface supports the fol-
lowing transfer rates:
•
9600 bit/s
•
19200 bit/s
•
38400 bit/s
•
57600 bit/s
•
76800 bit/s
•
