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+.
