This is a compilation of all the CODEC
board's connectors, mainly showing
the analog inputs, data received and
transmitted. The power,ground and
clocks are not shown, but they can be
found in the connectors chapter, or on
the schematics.

Analog signals
going out
to Analog I/O

CODEC 113
J15
J13
NOTE: the Bus numbers are reversed by
software, so Bus 1 is really Bus 8, Bus 2 is
really Bus 7 etc.
J11
Analog signals
going out
to DCA
J2 J1
J12
In other words, if you
looked at J-11 pin 1, this
is really Bus 8, not Bus 1.
