| Control Interface Adapter |
 |
General
The Control Interface Adapter is used in conjunction with the External RF Controller shown above. The "CIA" is
used as the physical interface to control legacy military radio equipment in real time.
Technical
The CIA employs an embedded controller system similar to the External RF Controller. It features
a wide variety of I/O to communicate with current and future equipment including RS232, RS485,
Ethernet, TTL I/O, Open collector drivers, and "FLEX I/O". The FLEX I/O is a custom programmable
I/O signal that can swing between any logic high and low voltages between -30 and +30 VDC. The
design also includes a reconfigurable FPGA to accomodate the interface to future equipment. The
embedded software and gate array configurations are fully downloadable via the Ethernet bus. The
design is expandable and includes an interface to an optional daughter-card that can house any
circuitry necessary to support future interfaces that can not be supported with the current suite
of on-board I/O. The CIA can be powered from AC mains or from 10-32VDC using an external power
supply.
