Terminal
Assignment
Label
The
terminal assignment label indicates
what
each module assigns
to
the
ter-
minals
of
module connectors
Jl
and J2.
The
top
half
of
the
label represents J 1
while the bottom half represents
J2.
The
narrow, right-hand
column
lists
the
connector row numbers 2 through
32
(even numbers only).
The
connectors
have
three columns
of
terminals labeled
E,
C,
and
A.
This forms a
row
and
column
matrix
for
locating a particular terminal.
For
example, Figure
29
shows
the
HP
34522 Digital
1/0
terminal assignment label.
To
find the terminal
that
the
bi-
directional data line
"13"
is
assigned to, look
at
the column-row matrix
to
see its
assignment
is
terminal E24 (column
E,
row 24)
of
connector J2.
