The next drawing shows a typical RJ45 connector. The color is not standard but very typical of an
Ethernet patch cable. Pin 1 is located at the top of the connector (orange + white). The view is
from the end of the connector.
Multi-Drop Ethernet Connections
Although there are two Ethernet ports, the XPress DR+ only has one MAC address and IP
address. Either port can be used as the primary connection with the other used to inter-connect
other Ethernet devices or cascade from one XPress DR+ to another.

Power Requirements

As with most industrial automation devices, the XPress DR+ does not ship with a power supply.
Its flexible power input circuit allows the product to be powered by any 9-30 VDC or 9-24 VAC
power supply with a Limited Power Source (LPS) which can provide the 2.3 Watt maximum
required by the XPress DR+ industrial device server.
In addition to the wide power input range, the XPress DR+ provides:
2K VAC and 2.8K VDC galvanic isolation between the power input and the Ethernet ports

2K VAC and 2.8K VDC galvanic isolation between the power input and the serial ports
