When the adapter is locked onto the DIN rail, gently push the FlexBus
connector into the adapter to complete the backplane.
8. Reinstall the module in the adjacent terminal base unit.
Connect Wiring
1. Connect an Ethernet network cable to the RJ45 connector (A).
2. Connect the redundant Ethernet network cable to the RJ45
connector (B).
3. Connect 24V DC common to the left side of the upper connector,
terminal F.
4. Connect +24V DC input power to the left side of the lower connector,
terminal C.
5. Connections D and E are used to pass +24V DC common (E) and 24V
DC power (D) to the next module in the series (if required).
Set the Network Address
The adapter ships with the thumbwheel switches set to 999 and DHCP enabled.
You can set the network Internet Protocol (IP) address in these ways:
• Use the thumbwheel switches on the module.
• Use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation DHCP.
• Retrieve the IP address (if previously set) from nonvolatile memory.
The adapter reads the thumbwheel switches first to determine if the switches are
set to a valid number. You set the node address by using the three-position
thumbwheel switch. Press the + or - buttons to change the number. Valid settings
are 001…254.
When the switches are set to a valid number, the adapter’s IP address is
192.168.1.xxx (where xxx represents the number set on the switches). The
adapter subnet mask is 255.255.255.0 and the gateway address is set to 0.0.0.0.
The adapter does not have a host name assigned, or use any Domain Name
System when using the thumbwheel settings.
If you set the switches to an invalid number (such as 000, or a value greater than
254), the adapter checks to see if you enabled DHCP.
Status Indicators
The module has LED status indicators to specify its status and aid the user in
troubleshooting.
WARNING If you connect or disconnect wiring while the field-side power is on,
an electrical arc can occur. This could cause an explosion in
hazardous location installations. Be sure that power is removed or the
area is nonhazardous before proceeding.
ATTENTION
• When connecting wiring, torque terminal screws C, D, E and F to
0.8 Nm (7 lb-in.).
• If multiple power sources are used, do not exceed the specified
isolation voltage.
• Power wiring must be less than 10 m (32.8 ft.) in length.
• Do not wire more than two conductors on any single terminal.

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.
