RS485 transmission
The OLCT 10N has 2 cable glands that are used for the input cable and the output
cable to the next module.
The detectors must be connected using MPI-22A cable type, minimum core size is
0.22 mm² (RS485 cable with 2 shielded twisted pairs, nominal impedance of
100 Ohm). This cable carries the RS485 signal on one pair and the power supply
for the modules on the other pair. The +24VDC, 0V, A and B terminals are
respectively connected to the +24VDC, 0V, A and B terminals of the other
