2 FF CARD PROPERTIES
2.1 Mechanical properties
The FF CP card consists of a single network interface card that fits directly to the main actuator control
PCB. It consists of two isolated parts, the actuator interface and the network interface
 Network Interface
This carries the FF highway connections and the processor handling the data highway
communication and function blocks. The Network Interface contains the FF connector (SK3),
polarised to prevent incorrect insertion. This connects to the three wire loom routed to the
terminal compartment of the actuator. Power for the Network Interface is taken from the FF
highway.
 Actuator Interface
The primary connection to the actuator circuits is by a multi-pin connector on the base of
Interface Card. The PCB design ensures it may only be fitted in the correct polarisation. The
Actuator Interface on the FF CP card is powered from within the actuator.
