Connecting
RS-232-C Devices
to
Chan-
nelS
Modems,
computers,
or
other
non-Allen-
Bradley
RS-232-C devices can be
connected
to
Channel
B
using
one
of
two
cables. These
cables are
three
feet
long
and
differ
only
by
the
type
of
connectors.
They
are:
•
Industrial
Terminal/Data
Handling
Adapter
Cable
(Cat. No. 1770-CB) - has
two
male
connectors
•
Industrial
Terminal
Adapter
Cable
(Cat. No.
1770-CC) - has
one
male and
one
female
connector
Cable
can be
constructed
for
distances
up
to
50 feet.
The
pinout
of
Channel
B (Figure 4-9)
identifies
the
pins used.
The
cable
to
be used
is Cat. No. 1778-CR,
Belden 8723
or
its
equiva-
lent
and is
constructed
as
shown
in Figure
4-10.
The
parts
for
constructing
this
cable are
listed in
Table
4-1.
Note
that
pins
7,
18,
and
25
on
the
Industrial
Terminal
CRT
Monitor
end
of
the
cable
must
be
wired
together.
For RS-232-C
applications
that
require
dis-
tances
greater
than
50 feet, refer
to
the
EIA
RS-232-C
Standards
publication
for
guide-
lines.
4.5.2
Connecting
a
PLC
Processor
for
Report
Generation
The
Industrial
Terminal
System, in
Alpha-
numeric
mode, can be used
for
report
genera-
tion
with
a PLC Processor.
The
Industrial
Terminal
System can be
connected
locally
(13
cable-feet)
or
up
to
5000
cable
feet
from
the
PLC Processor.
The
local
configuration
(Figure
4-11)
shows
a
Series B
or
later
Data
Handling
Module
(Cat.
No. 1774-DH2) in
the
PLC
Processor
Chassis.
The ten
foot
Data
Handling
Interconnect
Cable
(Cat. No. 1774-DC2)
connects
this
Module
to
one
end
of
the
1770-CB
Cable.
The
other
end
of
the
1770-CB
Cable
connects
to
Channel
B.
The
5000
cable-foot
configuration
(Figure
4-
12) uses
the
same Data
Handling
Module
and
cable, and a
section
of
constructed
cable
(Cat.
No. 1778-CR,
Belden
8723
or
equivalent).
