7.4 System Connections
The reciter can be fitted with an optional system interface PCB which
provides the links between the reciter’s internal circuitry and external
equipment. This PCB is securely mounted to the reciter’s chassis and is
connected to the control PCB with a flexible connector. The system
interface PCB is fitted with industry-standard connectors and several
standard types are available for different applications.
The circuitry on the system interface PCB provides additional signal
processing so that the outputs meet standard system requirements. It also
enables the PCB to identify itself to the reciter control circuitry.
The system interface PCB is removable, which makes it possible to change
the application of a reciter by removing one type of PCB and fitting another.
Only one system interface PCB can be fitted to a reciter at any one time.
This section provides details on the system interface PCBs available at the
time of publication. Other types may be developed for future applications.
Standard The standard system interface PCB is fitted to reciters bearing the product
code TBA4xxx-0A0x or TBA5xxx-0A0x. If purchased separately, it has the
product code TBA10A0. It provides:
■ non-isolated 600: balanced audio I/O
■ high impedance unbalanced audio I/O
■ Tx key
■ Rx gate
■ RSSI
■ Tx relay
