Pin Description
VIN+ Power supply input. Connect to the positive side of the appropriate power supply. DO NOT
EXCEED MAXIMUM POWER SUPPLY VOLTAGE.
Model X-WR-4R1-5
5VDC Power supply
Model X-WR-4R1-I
9~28VDC Power supply
Model X-WR-4R1-E
Power Over Ethernet model. These units do not require a power supply to be connected to this
pin when the unit is connected to an 802.3af compliant network. Alternatively, this model can be
powered using a 5VDC power supply.

Ethernet port instead of connecting an external power supply. In this case, WebRelay-Quad
through the network port. In an 802.3af compliant network, a 48 Volt power source is injected into the
Ethernet line. This power source is provided by an 802.3af compliant hub, switch, or power injector which
may be located in a utility closet which could be a distance away from WebRelay-Quad
very useful for installations where local power is not available. The power injector may inject the 48 Volt
power source through the data lines or the spare lines in the Ethernet cable. DO NOT USE A POWER
INJECTOR THAT APPLIES A VOLTAGE TO BOTH THE DATA LINES AND THE SPARE LINES.
