SUPER P4DC6/P4DC6+/P4DC6+II/P4DCE/P4DCE+/P4DCE+II User's Manual
Important !! The P4DC6/P4DC6+/
P4DC6+II/P4DCE/P4DCE+/
P4DCE+II must be connected
to supplemental 12v power
with the 4-pin J23 connector
and
the 8-pin J24 connector.
Failure to use a power supply
without such supplemental
12v power will result in CPU
instability after only a few min-
utes of operation.
