BUILDING
A
SYSTEM
Family
Compatibility
Mechanically,
the plug-in
modules
are very
similar
to
other
Tektronix
product
families.
However,
they are
not
electrically
compatible. Therefore,
the
TM
504 interface
has
barriers
on the
mating
connectors
between
pins
6
and
7
to
ensure
that
incompatible
modules
cannot
be
inserted.
See Figure
1.
A
compatible
module will have
a
matching
slot between pins
6
and
7
of its main
circuit
board
edge
connector.
This
slot
and
barrier
combination
Is
the
primary
keying
assignment.

500-compatible

modules

Identified

Customizing
The
Interface
The
modularity
of this
instrumentation
system provides
for many different
functions
to be performed
by the
plug-in
modules.
Specific
functions
are
grouped
into
families
or
classes,
of which
there
may
be
several
plug-in
module
members. For instance,
some
classes
are Power
Supplies,
Signal
Sources,
Measurement,
and
so forth.
Each
modular
member
of
a
functional
family
will have
a second
slot peculiar
to its family
assignment located
in its edge
connector.
The
TM 504 user
can
''program''
one
or
more
compartments
to accept
only
members
of
that
family
by
installing
a second
barrier in
the
interface
connector
to
match the module's slot
location. An
entire
TM 504
can
be
"programmed"
in this
manner
to
set
up
instruction
systems
for
specific
work functions.
For
extra
barriers,
order
Tektronix
Part
Number
214-1593-02.
Jumper
wires can
be
used
to further
specialize
the
interface.
Compartments can
be made
to "talk"
to
each
other
by connecting
jumpers
on
the back
side of
the
interface
board,
using pins
14
through
28,
A-side and
B-side
both, of the
interconnecting
jacks.
See the
following
description
of
Option
2. Refer
to
each
plug-in
module's
Manual for
the I/O assignments
of each pin
at
the
rear
Interface.
Once having
made
interconnections
of
a spe-
cialized
nature,
it is
recommended
that
barriers
be installed
on the
interconnecting
jacks
to
ensure
module
com-
patibility with the customized wiring.
