1747-KE DH-485/RS-232C Interface Module
1747-KE DH-485/RS-232C Interface Module
Solid state equipment has operational characteristics differing from those of
electromechanical equipment. Safety Guidelines for the Application,
Installation and Maintenance of Solid State Controls, publication SGI-1.1,
available from your local Rockwell Automation sales office or online at
http://www.literature.rockwellautomation.com, describes some important
differences between solid state equipment and hard-wired electromechanical
devices. Because of this difference, and also because of the wide variety of
uses for solid state equipment, all persons responsible for applying this
equipment must satisfy themselves that each intended application of this
equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for
indirect or consequential damages resulting from the use or application of
this equipment.
The examples and diagrams in this manual are included solely for illustrative
purposes. Because of the many variables and requirements associated with
any particular installation, Rockwell Automation, Inc. cannot assume
responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to
use of information, circuits, equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without

This preface covers the following topics.
• Who should use this manual
• The purpose of this manual
• Contents of this manual
• Terms and abbreviations
• Conventions used in this manual
The following terms and abbreviations are specific to this product. For
a complete listing of Allen-Bradley terminology, refer to the
Allen-Bradley Industrial Automation Glossary, publication AG-7.1.
ASCII Terminal - an industrial terminal, workstation, or personal
computer with terminal mode software (such as PBASE or Windows
HyperTerminal) that communicates in alphanumeric mode.
Backplane - a printed circuit board, at the back of a chassis, that
provides electrical interconnection between the modules inserted into
the chassis.
DF1 - a serial communication protocol capable of
delimiting-messages, controlling message flow, detecting and
signalling errors, and retrying after errors are detected. See half- and
full-duplex.
DH-485 Link - Data Highway-485 link. An Allen-Bradley token-passing
baseband link for a local area network based on the RS-485 standard.
Full-duplex - a mode of operation for a point-to-point link with two
physical circuits, in which messages or transmission blocks can be
sent in both directions at the same time.
Half-duplex - a mode of operation for a point-to-point or multi-point
baseband link with two physical circuits, in which messages or
transmission blocks can be sent in one direction or the other, but not
both at the same time.
Modem - Modulator/demodulator. Equipment that connects data
terminal equipment to a communication line.
RAM - random access memory. The type of memory in which each
storage location is by X/Y coordinates, as in core or semiconductor
memory. (Tape or bubble memory cannot be random access.) Thus,
the data access time is independent of the location of the data. Unless
stated otherwise, RAM usually implies read/write and volatile.
RS-232-C - an EIA standard that specifies electrical, mechanical, and
functional characteristics for serial-binary communication circuits in a
point-to-point link.
RS-422 - an EIA standard that specifies electrical characteristics of
balanced-voltage digital interface circuits in a point-to-point link.
RS-423 - an EIA standard that specifies electrical characteristics of
unbalanced voltage digital interface circuits in a point-to-point link.
RS-485 - an EIA standard that specifies mechanical and functional
characteristics for digital interface circuits. This standard is used in
combination with either RS-422 or RS-423.
SLC 500 controller - the SLC 500 family of fixed and modular
controllers.
