SECTION
IV
Configuring Within IOM
2.
Determine the quantity of physical
I/O channels your
planned mix of peripheral subsystems will require.
See Section D.
3.
Determine how many 12" x 12" circuit boards will be
required based on Step 2,
and how many are furnished
and can be added optionally,
if any,
for the Level 66
model you are configuring. See Section E.
4.
Determine how many logical channels or data paths
must be assigned, from the built-in complement of 24,
for the quantity of physical
I/O channels from Step
2.
Determine how many more you wish to assign
optionally,
if any. See Section F.
5.
Determine to how many, and which, logical channels
assigned
in Step 4 you wish to assign the scratchpad
capability which is furnished by DRE feature
(data
rate expansion). See Section G.
Steps for Configuring Within Freestanding IOM
1.
Base IOM
(freestanding systems)
has no type number.
All IOMs configured selectively beyond base IOM,
whether in ICU-packaged or freestanding systems, are
freestanding. This chart applies to all freestanding
IOMS.
a.
Freestanding IOMs may be obtained in 3 ways -—-
1)
One is included
in base CPS number of
freestanding systems.
2)
One or more may be ordered optionally on your
initial order along with the CPS components.
One more
is maximum of 66/40,
and 66/60/80
ICU versions;
up to
3
more on 66/60/80
freestanding versions, and DPS systems.
3)
One or more may be ordered optionally as
add—on components after your system has been
installed.
Limits are the same as in 2)
above
