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
receiver.
For optimum shielding, connecting cables with which the shield is routed on the knurled nut
of the housing coupling must be used (suitable cables are listed under accessories in
Chapter 12.3).
