15.6.1 Cable Assemblies

A cable assembly consists of a cable with one or two 12-way terminal blocks on one

end and a plug for connection to an Expansion I/O Board, SDE/SA Board or Main

Processor Board at the other.

The following types of cable assembly are normally used:

a) One terminal block and a plug for a single 8-input only port (two

buffered, six not) into PLE of the Main Processor Board.

b) Two terminal blocks and plugs for a 16-input only port (two buffered,

fourteen not) into PLE of the Main Processor Board.

c) A terminal block at one end and discrete Berg pins at the other for

inserting into the Main Processor Board Output port (PLC - 4 reed

relay outputs).

d) Two terminal blocks and plugs for connection to Expansion I/O Boards

or SDE/SA Boards.

There is a short and long version of each type of cable assembly to allow for the

different positions of the terminal blocks.

15.6.2 Extended System Bus

A ribbon cable is used to interconnect the Main Processor Board and the Expansion

I/O Boards and/or SDE/SA PCB via the Extended System Bus connectors.
