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+.
