M.1 Connections

This appendix describes the physical connections that you might have to make. It is pro-
vided to help those who may be unfamiliar recognize what the connectors are. I have pur-
posely left off the pin assignments and signal descriptions because it is better to use
store-bought cables than to make them up yourself—that is, unless you are building
studios on a large scale.
Most of the connection diagrams are shown looking directly into the pins of the con-
nector. Where it is helpful, a side view is also shown.

M.2 Signals Being Connected

Table M-1 summarizes the kinds of signals you can expect to encounter.
