External Antenna Options (
WB2011
Only)
The
WB2011
Master bridge unit does not include an integrated antenna, but
provides various external antenna options. In a point-to-multipoint configuration an
external high-gain omnidirectional, or panel antenna can be used to
communicate with up to 16 bridges spread over a wide area.
The external antenna connects to the N-type RF connector on the
WB2011
using
the provided coaxial cable.
Ethernet Port
The wireless bridge has one 10BASE-T/100BASE-TX 8-pin DIN port that connects
to the power injector module using the included Ethernet cable. The Ethernet port
connection provides power to the wireless bridge as well as a data link to the local
network.
The wireless bridge appears as an Ethernet node and performs a bridging function
by moving packets from the wired LAN to the remote end of the wireless bridge link.
Power Injector Module
The wireless bridge receives power through its network cable connection using
power-over-Ethernet technology. A power injector module is included in the wireless
bridge package and provides two RJ-45 Ethernet ports, one for connecting to the
wireless bridge (Output), and the other for connecting to a local LAN switch (Input).
Note: The power injector module does not support Power over Ethernet (PoE) based on
the IEEE 802.3af standard. The wireless bridge unit must always be powered on
by being connected to the power injector module.
The Input port uses an MDI (i.e., internal straight-through) pin configuration. You can
therefore use straight-through twisted-pair cable to connect this port to most network
interconnection devices such as a switch or router that provide MDI-X ports.
