Do
not
touch the

edge-connectors, board components
or
the printed cir·
cuit cable without observing static-discharge precautions. Handle the drive
by
the frame only.
Control
and
status signais between the host and the drive are transmitted through
a 34-pin PCB edge-connector,
JI.
Figure 3 indicates connector dimensions
and

llists
the pin assignments. A host/drive interconnection
is
illustrated in

Withthe drive resting
on
a padded surface, oriented with the Main Control PCB
up
and
the edge-connectors toward you,

is
to your left
and
J2
is on the right.
Refer to
Figure

pins are numbered 1through 34 with the even pins located
on
the component
side
of
the PCB.

odd
pins are ground. A
key
slot is provided between pins
4
and
