7.1.2.1 Transmission channel selection
The polarity of the power supply from Pin2 and Pin7 determines the selected optical
transmission channel.
If 24 V DC is present on Pin2 and 0 V on Pin3, transmission channel 1 is selected. If 0 V is
pres
ent
on Pin2 and 24 V DC on Pin7, transmission channel 2 is selected.
Note!
Make sure that you select the same transmission channel for both 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 12.4).
