Inasystemwheretheeldwiringisrequiredtobeconnectedtotherear
of the system, the rack is centrally divided into front and rear sections
by a printed circuit board backplane which provides common signal
routeing between individual Four Channel Control Cards. The control
cardsarettedatthefrontoftherackwhileQuadRelayInterfaceCards
aretteddirectlybehindtheassociatedFourChannelControlCardat
the rear of the rack. The control cards and their respective interface
cards are interconnected by a plug and socket arrangement.
Inasystemwheretheeldwiringisrequiredtobeconnectedtothefront
of a system, the Four Channel Control Cards and Quad Relay Interface
Cards are mounted one above the other in a 6U rack. The backplane
printed circuit board still provides the common signal routeing between
the individual Four Channel Control Cards, but short cables at the rear
of the cards connect each control card to their respective Quad Relay
Interface Card.
Simple calibration and checking of the system is carried out using push
buttons on the Engineering Card tted in each rack. More complex
conguration can be carried out using the RS232 link between the
Engineering Card and an external IBM compatible personal computer
running the engineering interface software.
When a Relay Interface Assembly is used, the resultant four channel
control assembly then takes up two card slots.
Amixtureof5704and5701ControlCardsmaybettedinthesame
System 57 rack.
The 5704 Control System is shown in Figure 1.
