1.
All RS-485 port cabling should be done with twisted pair type cable and if possible shielded, for best protection.
NOTE:
Although many cable types can be used to build the network with good results, we acknowledge that Cat 5e and Cat 6 based
networks might be the widest used type, so we will proceed with our guidelines assuming this type of cable is used.
2.
Maximum cable run between IC-XX-II and QIS Power and Communications Panel (PCP) should be limited to 200 ft.
3.
If more than one PCP device will be connected to a single IC-XX-II port, then these should be daisy chained, that is: these need to
be connected through RJ45 “third party Integration” connectors. See picture below. All PCP panels added to a IC-xx-II single RS-485
Port, it is recommended to have a maximum combined length of 200 ft. Along the same context, combined length of all segments
from PCP nodes to QIS shade devices, must not exceed 1000ft. In the figure below, combined length of Segments A+B+C should be
kept below 200ft.
NOTE:
If combined cabling from the RS-485 comm port to all the of the node devices exceeds 1,200 ft, then, an RS-485 Optical
Isolator/Repeater/Splitter should be used in order to increase the reach for another 1,200 ft of combined system cabling.
NOTE:
Combined cabling from IC controller,
through PCP nodes, including all branches to
QIS shades, must not exceed 1,200 ft.
