Crossover Wiring
Because the 10/100 Mbps port on the power injector uses an MDI pin configuration,
you must use "crossover" cable for network connections to PCs, servers or other
end nodes that only have MDI ports. However, if the device to which you are
connecting supports automatic MDI/MDI-X operation, you can use either
"straight-through" or "crossover" cable.

8-Pin DIN Connector Pinout
The Ethernet cable from the power injector connects to an 8-pin DIN connector on
the wireless bridge. This connector is described in the following figure and table.
