Interconnections
The pictorial below depicts the Q5 processor board, and the necessary interconnects between it and the Interface board. Each
of the interconnecting harnesses must be installed as shown for proper operation.
If the harness for either
COMM 1 or COMM 2 is
ever removed for repair,
replacement, or trouble-
shooting, ensure that the
pinout matches as shown
here when plugging the
ends back in. All other
Interconnection harness
ends share the same pin-
out at both ends.
