ASSEMBLY
3.0
GENERAL
Before
any
Industrial
Terminal
System
can be
used,
it
must
be set
up
for
proper
operation.
This
includes
selecting
the
correct
input
voltage,
line
frequency,
and fuse, and
setting
the
correct
baud
rate
and
parity
for
Channels
Band
C.
Since
all
Industrial
Terminal
Systems
are set
up
in
the
same
manner,
the
information
in
this
section
applies
to
all systems.
3.1
KEYBOARD
INSTALLATION
Perform
the
following
steps
to
attach
the
keyboard
to
the
Industrial
terminal:
1.
Loosen
the
mounting
screws
on
the
key-
board
connector
cover
and remove
the
con-
nector
cover.
2.
Be
sure
the
power
switch
is off.
3.
Lift
and
move
the
locking
lever
to
the
UNLOCK
position.
4.
Align
the
two
support
pins
on
the
keyboard
with
the
bushings
on
the
front
of
the
chassis
(Figure
3-1) and
insert
the
keyboard.
5.
Lift
and
move
the
locking
lever
to
the
LOCK
position.
Note
that
the
PLC-2
Family
Keyboard
(Cat.
No. 1770-FD)
and
the
PLC-3
Keyboard
(Cat.
No. 1770-FE) have a
projection
on
the
back
that
fits
into
the
Industrial
Terminal
CRT
Monitor.
This
projection
is
designed
to
fit
into
a
notch
on
a
Series
8
Industrial
Terminal
Monitor.
Series A
Industrial
Terminal
Moni-
tors,
shipped
with
earlier
1770-
T1
and
-T2
systems,
do
not
have a
notch.
Thus, 1770-FD
and 1770-FE
Keyboards
can
only
be used
with
Series 8
Industrial
Terminal
Monitors.
3.2

desired
keytop
overlay
is
easily
installed
on
