Overview
Every D-8000 has these two modules; together
they perform all central signal and control processing
for the console. The CPU-8 or CPU-8S is the console’s
central controller module; the DSP-8 is the console’s
digital signal processor.
The D-8000 Digital Audio console is provided
with a serial interface port, which is located on the
lower DB-25 connector of the CPU-8 or CPU-8S
module (see connection diagrams for pinouts and
other details). This serial interface is designed to
provide a number of functions including external
control and set-up, software updates, system inter-
face, etc. Through this serial interface, the D-8000
control protocol is available, allowing visibility and
control of the console switches, displays, and other
functions. The “Virtual Dip Switch” application pro-
gram (supplied with the D-8000 console) communi-
cates set up information through this serial interface
(see Chapter 9).
There are no user replaceable parts inside (though
complete modules may be ordered; see Appendix I).
