1.8 Network Connectors (continued)
1.8.1 Compatible Connectors and Cordsets
Many different connectors and cordsets are available on the market, all of which will work with the
SMD23E2 and SMD24E2 provided that the manufacturer follows the connector and Ethernet standards.
AMCI offers the following mating connector and cordsets that mate with the Ethernet port connectors.
Table T1.4 Compatible Ethernet Connectors and Cordsets
1.8.2 TIA/EIA-568 Color Codes
There are two color codes in common use when wiring Ethernet connections with twisted pairs. Either one of
these standards is acceptable. The CNER-5M cable available from AMCI follows the 568B standard. Note
that accidently reversing the Tx/Rx pairs will not affect the operation of the SMD23E2 and SMD24E2. Each
unit has an “auto-sense” port that will automatically adjust for swapped pairs.

1.9 EtherNet/IP Connections
1.9.1 Non-DLR Applications
The SMD23E2 and SMD24E2E2 units have two Ethernet ports with a built-in Ethernet switch connecting the
two. In non-DLR applications, either port can be used to attach the unit to the network. The remaining port
can be used to extend the network to another device if this would reduce wiring costs.
1.9.2 DLR Applications
In Device Level Ring applications, the SMD23E2 and SMD24E2 units function as Beacon-Based Ring
Nodes. In these applications, both ports are used when wiring the ring, daisy chaining from one unit in the
ring to the next.
