6.5  Quick Connector

The Quick Connector is a unique feature of modules that allows for quickly connecting a 

group of devices with a flat ribbon cable. Thanks to this solution, it is enough to connect 

power and RS485 communication to one of the devices in the group, and the others will 

be powered and communicated with ribbon cable. The Quick Connector is sufficient to 

connect  up  to  10  devices  next  to  each  other.  It  is  important  that  the  various  types  of 

modules in the SfAR-S family can be connected with the ribbon cable.
