13.4.1 Backplane Addressing
The backplane interfaces to the traffic controller using the SIO (serial I/O) protocol. This
use of this interface (Ethernet cable) and protocol (SIO) means that the standard interface
card, as far as the controller is concerned, will 'look' like an I/O board.
This means the standard interface card will need to have an address set.
Note: The interface card address can be found in the controller configuration.
Note: For addresses between 0 and 15, the user must ensure that the address
link is in place (Reference Figure 57 below).
The card address is set by using the small rotary switch on the backplane. By locating the
address switch on the backplane, the standard interface card can be replaced without
having to reset the card address.
Note: The standard interface card uses a non-standard detector backplane
(667/1/47217/300) which is supplied as part of the WiMag standard interface kit
(667/1/47210/100).
Note: The power at the backplane is derived from the controller's serial interface
interconnect system. The controller serial interface system is not the same as
Ethernet and must not be routed to any of the Ethernet switches.
