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

2.4 Power and Ethernet
The BreadCrumb ES1 has one RJ45 Ethernet port. The Ethernet port (ETH0) on the BreadCrumb ES1 sup-
ports 10 Base-T, 100 Base-TX or 1000 Base-T configuration. The port supports Auto MDI/MDIX allowing
the use of either straight-through or crossover data cables for connections. The data interface includes
