External antennas connect to the N-type RF connectors on the wireless bridge using the optional RF coaxial cables.

Using the external antennas in a point-to-multipoint deployment, the maximum range for bridge links are:

„802.11b,g: 2.2 km

„802.11a: 3 km

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.

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.

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).

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
