AirConnect Access Point

A wireless client communicating with an AP appears on the network as a peer to other network devices, rendering the wireless interface transparent. The AP receives data from its wired interfaces and forwards the data to the proper interface.

The AP has connections for wired networks, built-in antennas, and a power supply. It attaches to a wall or ceiling, or can be placed on a ﬂat surface, depending on installation-site requirements. The AP uses a diversity antenna for radio transmission and reception, allowing the AP to automatically select the strongest of the radio signals picked up by the antenna.

AP Features ■ Built-in diagnostics (including a power-up self-check)

■Wireless MAC interface

■Upgradable ﬁrmware

■10BASE-T Ethernet port interface with full-speed ﬁltering

■Power supply IEC connector and a country-speciﬁc AC power cable

■PC/AT Serial Port Interface

■Built-in antenna diversity

■Support for up to 63 wireless clients

■SNMP support

■IEEE 802.11 MIB support

■DHCP support

■HTTP Web server support.

PowerBASE-TThis device allows the AP to be powered through the Ethernet cable connecting the AP to a LAN. The PowerBASE-T should be used when the AP is connected to LAN and is mounted in a location where access to a standard electric outlet is severely limited.
