DRd Rack Enclosure Installation Manual
The riser below is typical of a Unison system utilizing Paradigm Architectural Control
Processors (P-ACP) for control and Unison architectural control stations for user controls.
Paradigm systems provide a DMX input into the system for larger system integration and
control. A Paradigm system also utilizes Net3 networking for an additional level of system
wide control.
Control Wire Specification
The following table lists the recommended control wire types used in Unison DRd rack
installations and the maximum length (aggregate) of wire runs allowed.
Data Types and Topologies
LinkConnect with LinkPower
LinkConnect is the station communication bus from the Architectural Control Processor to
the stations. LinkConnect is based on Echelon
®
LonWorks™ with LinkPower bidirectional
protocol, and uses one pair of wires (data +, data -). You should pull an additional 14 AWG
(1.5mm
2
)wire for grounding when not installed in grounded metal conduit.
ETC uses two types of LinkConnect networks, for SmartLink and Paradigm systems. While
the wiring for LinkConnect in SmartLink and Paradigm systems are the same, the two
communication and control types are not interchangeable. SmartLink products are
compatible only with the SmartLink ACP, SmartLink station power module, and SmartLink
architectural control stations. Paradigm products are compatible only with the Paradigm
ACP, Paradigm station power modules, Unison Heritage architectural control stations, and
Paradigm touchscreens.
Throughout this manual LinkConnect is referred to by the protocol it uses, LinkPower.
N o t e :
DRd rack enclosures are shipped with the lugs installed in a top feed orientation
by default. You may change the lug orientation to a bottom feed as needed.
