Part 3: Setup and Initialization

Summary

TheXPress™EthernetBridgeallowstheusertocreatealong‐range,wirelessEthernetnetworkwithupto

16active(63total)subscriberunitsperaccesspoint.

ConfiguringawirelesslinkwiththeXEBrequirestheestablishmentofsixelements:

• Eachradiomustknowwhetheritistobeanaccesspoint(AP)orsubscriberunit(SU)

• EachradiomusthaveanIPaddressthatisuniqueamongallothers onthesamenetwork

• TheAPmustknowhowmanySUsareexpectingcommunicationwithit

• TheAPandanygivenSUmustagreeonwhichradiofrequencychanneltheyareusing.

Thiscanbesetmanuallyorallowedtochangeautomatically.

• TheSUmustbeassignedauniquesubscriberIDtospecifywhichtimedivisionslotitwilluse

whencommunicationwiththeAP

• TheAPandanygivenSUmustshareac ommon128‐bitencryptionkey

Theaccesspoint(AP)automaticallyscansforthebestofthe12availableradiofrequencychannels,

encryptsEthernetdatareceivedfromthenetwork,andtransmitsitwirelesslytothecorrectsubscriber

unit(SU).TheAPisconstantlymonitoringtheradiolinkandcanautomaticallychangethechannelif

performanceisdegraded

duetointerference.IftwoAPunitsareveryclosetooneanother,theymay

interfereifoperatingonadjacentfrequencychannels.Placethematleast10feetapartormanuallyselect

non‐adjacentchannelsfortheiroperation.Also,theSUshouldbeplacedatleast10feetfromthe

APto

avoidoverloadingtheradio’ sreceiver.

Any10/100BaseTEthernetclientdevice(ECD)canbeconnectedtoanXPress™subscriberunit.EachSU

encryptsEthernettrafficreceivedfromtheattachedECDandtransmitsthedatawirelesslytoitsAP.Each

SUcanbepluggeddirectlyintoanECDwithoutaddingdriversorloadingsoftware.Essentially,oncethe



AP/SUpairisconfiguredandrunning,itbehaveslikeacontinuousEthernetcable.
