Installation Instructions
ArmorPoint DeviceNet Adapters, Series A
(Cat. No. 1738-ADN12, -ADN18, -ADN18P, -ADNX)
The ArmorPoint™ family of DeviceNet™ adapters (Cat. no. 1738) ship
with the adapter and a terminating base to be used with the last I/O
module on the backplane. The sealed IP67 housing of these adapters
requires no enclosure. (Note that environmental requirements other
than IP67 may require an additional appropriate housing.) DeviceNet
connectors are sealed M12 (micro) or M18 (mini) styles. The
DeviceNet adapters are shown below.

Important User Information
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.ab.com/manuals/gi) 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 written permission of Rockwell
Automation, Inc. is prohibited.
Throughout this manual we use notes to make you aware of safety considerations.
WARNING Identifies information about practices or circumstances that can cause an explosion in a
hazardous environment, which may lead to personal injury or death, property damage,
or economic loss.
IMPORTANT Identifies information that is critical for successful application and understanding of the
product.
ATTENTION Identifies information about practices or circumstances that can lead to personal injury or
death, property damage, or economic loss. Attentions help you:
•identify a hazard
•avoid a hazard
•recognize the consequence
SHOCK HAZARD
Labels may be located on or inside the equipment to alert people that dangerous voltage
may be present.
BURN HAZARD Labels may be located on or inside the equipment to alert people that surfaces may be
dangerous temperatures.

ATTENTION Environment and Enclosure
This equipment is intended for use in overvoltage
Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters
without derating.
This equipment is considered Group 1, Class A
industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring
electromagnetic compatibility in other environments
due to conducted as well as radiated disturbance.
This equipment is supplied as "enclosed" equipment.
It should not require additional system enclosure
when used in locations consistent with the enclosure
type ratings stated in the Specifications section of this
publication. Subsequent sections of this publication
may contain additional information regarding
specific enclosure type ratings, beyond what this
product provides, that are required to comply with
certain product safety certifications.
NOTE: See NEMA Standards publication 250 and
IEC publication 60529, as applicable, for
explanations of the degrees of protection provided
by different types of enclosure. Also, see the
appropriate sections in this publication, as well as
the Allen-Bradley publication 1770-4.1 ("Industrial
Automation Wiring and Grounding Guidelines"), for
additional installation requirements pertaining to this
equipment.

Mount the Adapter and
I/O Base
To mount the ArmorPoint adapter on a wall or panel, use the screw
holes provided in the adapter.
A mounting illustration for the ArmorPoint adapter with I/O bases is
shown below.
Install the mounting base as follows:
1. Lay out the required points as shown above in the drilling
dimension drawing.
2. Drill the necessary holes for #8 (M4) machine or self-tapping
screws.
ATTENTION Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic discharge,
which can cause internal damage and affect normal
operation. Follow these guidelines when you handle
this equipment:
•Touch a grounded object to discharge potential
static.
•Wear an approved grounding wriststrap.
•Do not touch connectors or pins on component
boards.
•Do not touch circuit components inside the
equipment.
•If available, use a static-safe workstation.
•When not in use, store the equipment in
appropriate static-safe packaging.

3. Mount the adapter and I/O bases using #8 (M4) screws.
4. Ground the system using the ground lug connection in the I/O
base. (The ground lug connection is also a mounting hole.)
5. Mount the terminating base that was shipped with the adapter as
the last base in the backplane instead of the base that was
shipped with the I/O module.
Set the Node Address
Valid node addresses are 00 through 63.
Set the node address using either the rotary switches, RSNetWorx for
DeviceNet, DeviceNetManager, or another software configuration
tool. Setting the switches at any number from 64 through 99 lets the
software have address control.
Each module is shipped with the switches set for node address 63.
Remove the caps on the front of the module to access the switches
(refer to the illustrations on page 1). The two switches are:
•X10 (most significant digit) - left side of module
•X1 (least significant digit) - right side of module
To reset the node address, use a small blade screwdriver to rotate the
switches. Line up the small notch on the switch with the number
setting you wish to use and then cycle power.

6ArmorPoint DeviceNet Adapters, Series A
The rotary switches are read periodically. If the switches have been
changed since the last time they were read and they no longer match
the on line address, a minor fault will occur, which is indicated by a
flashing red Adapter Status LED. Settings of 64 through 99 cause the
module to use the last valid node address stored internally. Example:
The last setting internally was 40. If a change is made to 68, and then
you power up, the address will default to 40.
The module is equipped with AutoBaud detect. AutoBaud lets the
module read the settings already in use on your DeviceNet network
and automatically adjusts to follow those settings.
