SHORTING PLUG OPTIONS
There are seven shorting plug options which must be set before
using the board. These are outlined below:
LK1–LK4
Connects the analog inputs to the buffer amplifi-
ers. The analog inputs may also be connected to a
component grid for signal conditioning.
LK5
Selects either the AD7874 internal clock or an ex-
ternal clock source.
LK6
Selects either the AD7874 internal reference or an
external reference source.
LK7
Connects the AD7874 RD input directly to the
RD
input of SKT8 or to a decoded STRB and
R/W input. This shorting plug setting depends on
the microprocessor, e.g., the TMS32020 and
68000 require a decoded RD signal.
