2.2 FSL-CONTROL II communication
2.2.1 Several controllers in a control zone
Connect FSL-CONTROL II controllers (master-slave)
within a control zone with a standard network cable
(RJ45, to be provided by others).

Up to 300 m network cable for each control zone
Network cable type SF-UTP (braided and with foil),
to ISO IEC 11801 (2002), as a patch cable with
RJ45 plugs on both ends, or from a roll, at least cat.

Terminal resistor / termination
Fault-free data exchange between the controllers
requires that both ends of the communication cable are
terminated.
