1 Introduction
This document gives a short introduction to the e:bus system. e:bus is a bus system developed by Traxon
e:cue for secure, bi-directional and fast system link between e:bus enabled user terminals.
1.1 Advantages of the e:bus system
Thee:busnetworkingplatformoersseveralfeaturesforasimpleinstallationandgreatreliabilityinreal
installations.
ye:busisaself-organizingnetwork.Thissimpliescongurationbyaplug&play-likebehaviour.The
addressing happens automatically.
yLinkpower.Userinterfacesaredirectlypoweredovere:bus.Fewerwiresmakethehardware
installation much easier.
yThe connections are a very reliable and a stable communication basis with polarity-insensitive wiring.
At the end of this document (see page 06),youcanndashortcomparisonofe:buswithDALIandDMX
based communication.
1.2 General information
yUptoeightdevicescanbeconnectedtothee:bus,organizedbyasignlemasterdevice.
yFreetopologyarchitectureallowsthedevicestobeconnectedincombinationofstar,busandtree
structures.
ye:bus is designed for cable lengths of up to 400 meters, depending on cable type, topology and number
of connected devices. A bus topology allows the largest cable length.
yThe maximum stub length is 30 cm.
yInterfaces are powered via e:bus.
yInterfaces will be automatically registered and addressed.
yDefectiveunitswillnotaectthecommunicationbetweenotherdevices.
yAmaximumofeighte:busdevices,e.g.e:cueGlassTouches,issupportedbyoneSYMPLe:busNode.
!
e:bus network communication cables should be seperated
fromhighvoltagepowercables.Followlocalelectricalcodes
with regard to cable placement.

2.1 Wiring
The e:bus is a 2-wire-bus system using screw terminal connectors to attach the wires safely and robust. The
wiringbetweenthedevicesisextremelyexible.Inadditiontothefreetopologydesign,youdonotneedtopay
attention to polarities. As long as the two e:bus connectors of a user terminal are connected to the master
unit’sconnectors,regardlessifacablegoesfrom+to+orfrom+to-,everythingwillworkne.Thetwoe:bus
connectors of a user terminal can be connected to the master unit‘s connectors either way. The terminal
deviceswillrecognizethepolarityontheirownandcongurethemselvestheproperway.

2.2 Invalid congurations
Donotaddasecondmastertoane:bus
network!
Donotleaveanywiresopen!Openwireswillcausesignal
reectionsandthereforedisruptcommunication.

3 Cable types and lengths
3.1 Cable types
The maximum cable length is greatly dependent on device count, topology and cable types as well. Approved
cabletypesfore:busareAWG16(1.5sqmm)cablesandAWG24(0.28sqmm)Cat5orJ-Y(St)Ycables.The
following table shows valuable key facts:

4.1 Glass Touch
FortheGlassTouchthevaluesabovearenotvalid.Instead,watchtheserequirements:
yUse2x0.5sqmm.
yUseadirectconnectionfromSYMPLe:busNodetoGlassTouch,nobranching.
yMaximumcablelengthis100m.
5 e:bus, DALI and DMX
5.1 DALI
DigitalAddressableLightingInterface(DALI)isastandardforcontrollightinginbuildings.Itwasestablished
asasuccessorfor0...10Vlightingcontrolsystems,andasanopenstandardalternativetoDigitalSignal
Interface(DSI),onwhichitisbased.TheDALIstandard,whichisspeciedintheIEC60929standardfor
uorescentlampballasts,encompassesthecommunicationsprotocolandelectricalinterfaceforlighting
control networks.
5.2 DMX
DMX512(DigitalMultiplex)isastandardfordigitalcommunicationnetworkstocontrolstagelightingand
eectssuchasfogmachinesandmovinglights.DMX512employsEIA-485dierentialsignalingatitsphysical
layer,inconjunctionwithavariable-size,packetbasedcommunicationprotocolat250kBit/s.Itis
unidirectionalanddoesnotincludeautomaticerrorcheckingandcorrection.DMXisthemostused
connection type in lighting control.
