Signal Interface Concentrators (SICs)
While the SMCS card cage is the central brain of the SMCS, the control
and monitor signals of the SMCS must reach the electrical hardware that
it is measuring and controlling. To achieve this signal distribution, the
SMCS includes many “Signal Interface Concentrators’ PCBAs (SICs)
located throughout the SM.
The SICs provide a local place where the individual elements of the
particular subsystem of the SM have their electrical signals
“concentrated.” In some cases, there is ESN capability on the SICs.
Power SIC # 101-5020
The Power SIC provides a controlled interface between the DC power
supply, and the rest of the SMCS. It also provides controlled power to the
Strobe. The Power SIC is mounted atop the SMCS Cardcage, and
interfaces to backplane connector J15 through a 10-wire ribbon
connector, and to backplane connector J16, a 14-wire discrete wire
connector with large gauge wires carrying the actual power signals. The
Power SIC receives power directly from the DC Power supply via another
10-pin discrete wire connector. It also provides 12-volt regulated power
to the CCD camera. The power delivered to the Cardcage (and the rest
of the SMCS) is switched off and on by a logical signal from the SM front
panel “Standby” switch.
The Power SIC connectors are summarized in table below.
