SHORT ING PLUG OPT IONS
T here are seven shorting plug options which must be set before
using the board. T hese are outlined below:
LK 1–LK 4
Connects the analog inputs to the buffer amplifi-
ers. T he analog inputs may also be connected to a
component grid for signal conditioning.
LK 5
Selects either the AD7874 internal clock or an ex-
ternal clock source.
LK 6
Selects either the AD7874 internal reference or an
external reference source.
LK 7
Connects the AD7874
RD
input directly to the
RD
input of SK T 8 or to a decoded
STRB
and
R/
W
input. T his shorting plug setting depends on
the microprocessor, e.g., the T MS32020 and
68000 require a decoded
RD
signal.
