About The Adapter
The Series B 1738-AENTR ArmorPOINT I/O Dual Port EtherNet/IP Adapter provides
connectivity to an EtherNet/IP network via two M12 EtherNet-keyed connectors for
2-port pass-through to support daisy chains or rings, and the existing star and tree network
topologies.
The adapter ships with a terminating base to be used with the last I/O module on the
backplane. The sealed IP67 housing of the adapter requires no enclosure (environmental
requirements other than IP67 may require an additional appropriate housing).
The EtherNet/IP connector is a sealed D-coded M12 (micro) style connector.

Before You Begin
To effectively use your adapter, note the following considerations.
Determine Compatibility
RSLogix™5000 version 17 or greater must be used for the 1738-AENTR Add-on Profile.
The 1738-AENTR adapters will accept I/O connections with electronic keying for the
1738-AENT. This allows the 1738-AENTR adapter to be used in a daisy-chain topology
with the 1738-AENT profile used for the 1738-AENTR.
If using the adapter with a 1756-ENBT module, 1768-ENBT module or an L3xE
processor, use the following required firmware versions for these bridge modules:
• 1756-ENBT firmware version 4.5 or greater
• 1768-ENBT firmware version 2.1 or greater
• L3xE processor firmware version 17 or greater
If you use the BootP/DHCP utility to assign IP addresses to the adapter, use version 2.3.2
or greater.
Understand Messaging
Class 3 (Explicit Message) requests through the 1738-AENTR adapter to a specific
ArmorPOINT I/O module do not always receive a response from the module. In the case
where an ArmorPOINT module does not reply to a request, the adapter responds with an
error code indicating a time-out.
Configure Autobaud
The adapter cannot reconfigure an I/O module that you previously configured to operate
at a fixed baud rate. When you reuse an ArmorPOINT I/O module from another
ArmorPOINT I/O system, configure the module to autobaud before using it with the
adapter.

Mount the Adapter and I/O Base
To mount the ArmorPOINT I/O adapter on a wall or panel, use the screw holes provided
in the adapter. A mounting illustration for the ArmorPOINT adapter with several
attached I/O bases is shown below.
Mounting illustration for ArmorPOINT I/O adapter with I/O Mounting bases
Install the adapter and its I/O Mounting base as follows:
1. Lay out the required points as shown above in the drilling dimension drawing.
2. Drill the necessary holes for M4 (#8) machine or self-tapping screws.
3. Mount the adapter using M4 (#8) screws.
ATTENTION: This product is intended to be mounted to a well-grounded
mounting surface such as a metal panel. Additional grounding connections
from the power supply's mounting tabs or DIN rail (if used) are not required
unless the mounting surface cannot be grounded. Refer to Industrial
Automation Wiring and Grounding Guidelines, Rockwell Automation
publication 1770-IN041, for additional information.
ATTENTION: To comply with the CE Low Voltage Directive (LVD), this
equipment must be powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).

4. Ground the system using the ground lug connection in the adapter’s I/O base.
(The ground lug connection is also a mounting hole).
5. Add one or more I/O modules and their respective I/O mounting bases to the
adapter and its I/O Mounting base as required. See Set the Network Address on
page 9 for details.
6. Mount the terminating base that was shipped with the adapter as the last base in
the backplane instead of the I/O Mounting base shipped with the I/O module.
ATTENTION: If this equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.

Publication 1738-IN030A-EN-P - July 2013
Set the Network Address
The adapter ships with the rotary network address switches set to 999 and DHCP
enabled. To change the network address, you can:
• adjust the switches on the front of the module
• use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation BootP/DHCP.
• retrieve the IP address from nonvolatile memory
The adapter reads the switches first to determine if the switches are set to a valid number.
You set the network address by adjusting the 3 switches on the front of the module. 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. Valid settings range from 001...254.
When you use the switches to assign an address and set it to 001, the adapter gateway
address is set to 0.0.0.0. and the subnet mask is 255.255.255.0 . When you use the
switches to assign an address and set it between 002...254, the adapter gateway address is
set to 192.168.1.1.
The adapter does not have a host name assigned, or use any Domain Name System when
using the switch settings.
Network Address Switches
Refer to publication POINT I/O and ArmorPOINT I/O Dual Port EtherNet/IP
Adapter User Manual, 1734-UM017 for more information on adapter configuration.
If you set the switches to an invalid number (for example, 000 or a value greater than 254
excluding 888), the adapter checks to see if you enabled DHCP.
DHCP Enabled and Not Enabled
DHCP State Adapter Action
Enabled Asks for an address from a DHCP server. The DHCP server also assigns other
Transport Control Protocol (TCP) parameters.
Not enabled Uses the IP address (along with other TCP configurable parameters) stored in
nonvolatile memory.
This example shows the
network address set at 163.

IMPORTANT
Analog modules have earth grounded metal rings. This should be
considered when choosing shielded cables and grounding techniques.
ATTENTION: Make sure all connectors and caps are securely tightened to
properly seal the connections against leaks and maintain IP enclosure type
requirements.
(1) Auxiliary power cable: standard cordset (single-ended), for example Allen-Bradley part number 889N-F4AFC-6F or
889N-R4AFC-6F; or standard patchcord (double-ended), for example, Allen-Bradley part number 889N-F4AFNU-6F or
889N-F4AFNV-6F. Refer to publication M117-CA001A-EN-P for more information.
