The standard interface card will allow the controller to interface with up to
twenty
wireless
sensors and
four
fault output states.
The standard interface card provides a bridge between the Sensys equipment (access
point, repeater and sensor) and the traffic controller, using the SIO (serial I/O) protocol.
The interface between the card and the controller is an Ethernet cable. The protocol (SIO)
means that the standard interface card, as far as the controller is concerned, will ‘look’
like an I/O board.
The card requires an address to be set for SIO functionality. The backplane provides a
rotary address switch for the purpose.
Each magnetometer sensor is mapped, at the access point, such that the detection from
a sensor is routed to an interface card. Please refer to section 7 for details on configuration
and mapping. The interface card is integrated to a controller installation thus providing a
link between the magnetometer sensor and the controller.
Each interface card can cater for a maximum of 20 sensors along with an additional 4
fault outputs.
Each fault output state is a multiplexed state of five detector fault states. i.e. faults for
detectors 1 to 5 multiplex to fault 1 output on the Standard Interface Card.
The 20 detector states and 4 fault states map to the equivalent of the 24 inputs from an
I/O card.
The backplane uses a rotary switch to set the card address as per an I/O card.
There are three LED indicators on the front panel which provide status and fault indication.

Controller Configuration
When using IC4 to generate a controller configuration, the recommendation is to
select 24/0 as the card interface type
.
