The polarity of the power supply from Pin1 and Pin3 determines the selected optical
transmission channel. If 24 V DC is present on Pin1 and 0 V on Pin3, transmission
channel 1 is selected. If 0 V is present on Pin1 and 24 V DC on Pin3, transmission
channel 2 is selected.
Note!
Make certain you select the same transmission channel for both, for transmitter and
recei
v
er.
For optimum shielding, connecting cables with which t
he shield is routed on the knurled nut
of the housing coupling must be used (suitable cables are listed under accessories in
Chapter 12.3).
