XPress DR+ User Guide 24
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 that can provide the 2.3-Watt maximum required by the
XPress DR+.
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
Reset Switch
The XPress DR+ includes a hardware reset switch located in the small hole above the
power connector. Pressing the reset switch causes a hardware reboot of the
XPress DR+. The hardware reset does not reset or change the configuration of the
XPress DR+.
