Figure: Incorrect Antenna Placement
Most of Rajant’s standard antennas are characterized by high-gain and, therefore, small vertical
beamwidth. Antennas in fixed locations should be installed plumb and at the same elevation so that
BreadCrumbs using these antennas will see each other without a significant loss of signal strength.

2.4 Power and Ethernet
2.4.1 Ethernet Port ETH0
The BreadCrumb ES1 has one RJ45 Ethernet port (ETH0). On the BreadCrumb ES1, port ETH0 supports 10
Base-T, 100 Base-TX or 1000 Base-T configurations for Ethernet data and supports both Mode A and Mode
B for Passive Power over Ethernet (Passive PoE). Therefore, ETH0 acts as a dual function Ethernet and DC
power input port for the BreadCrumb ES1.
