2.6 System Interface Boards
The reciter can be fitted with an optional system interface board which
provides the links between the reciter’s internal circuitry and external
equipment. This board is securely mounted to the reciter’s chassis and is
connected to the digital board with a flexible connector. The system
interface board is fitted with industry-standard connectors and several
standard types are available for different applications.
The circuitry on the system interface board provides additional signal
processing so that the outputs meet standard system requirements. It also
enables the board to identify itself to the reciter control circuitry.
The system interface board is removable, which makes it possible to change
the application of a reciter by removing one type of board and fitting
another. Only one system interface board can be fitted to a reciter at any
one time.
The following section provides an overview of all the system interface
circuitry. However, not all the circuitry described here will be fitted to any
particular system interface board. The different types of board and their
main features are listed in Table 2.1 on page 55. Refer also to Figure 2.12
on page 56.
