Intelligent Detector Backplane Card

The Intelligent Detector Backplane provides an interface for up to 4 loop detector
cards, each loop detector card connecting to 4 loops.
The Intelligent Detector Backplane connects to the CPU Card or previous Intelligent
Detector Backplane via the GSPI interface serial cable through which the card also
obtains its power supply.
A twisted ribbon cable provides the connection between the loop detector cards and
the road loops, via the loop termination card. The /950 variant also includes
additional connectors to allow the SLD4 loop detector auto-configuration
communications link to be wired between multiple backplanes within a controller.
