DMX Input/Output Termination: Insulation Displacement Connectors
The graphic below illustrates DMX termination layout for an insulation displacement
connector (IDC). This connector type is intended for use with belden 1583A (or approved
equal, such as Category 5, 5E, or 6) cable type.
The insulation displacement connector kit (IDC) may be requested from the factory but is
not supplied as standard. Request the IDC Pluggable Connector Termination kit, part
number 4100A1013. Be aware that cable other than Belden 1583A may have different color
code for its wire pairs.
Terminate LinkConnect Control Wiring
Unison control stations communicate with the Paradigm Architectural Control Processor
using the Echelon
®
LinkPower network (LinkConnect). Termination is available for up to
twelve home runs of LinkPower data runs utilizing Belden 8471 cable (or its equivalent) plus
one 14 AWG (2.5mm 2 ) ESD drain wire when the data cable is not installed in grounded
metal conduit.
LinkPower wiring is topology-free and polarity independent utilizing a LinkPower network.
Wiring may be bus, star, loop, home run or any combination of these. Total combined length
of LinkPower data runs cannot exceed 1,640 feet (500m), with a maximum distance of
1,313 feet (400m) between any two communicating devices. Without a repeater, no device
may be more than 1,313 feet (400m) away from the Architectural Control Processor.
Standard interoperability requires that there should be a maximum of only one station
repeater between any two LinkConnect devices. This means that only one repeater
module, whether a Paradigm Repeater module (P-REP) or a Paradigm Dual Repeater
Module (P-DREP), may be used per Paradigm Architectural Control Processor (P-ACP).
Step 1: Pull Belden 8471 (or an equal type) control wiring into the ERn enclosure through
the conduit opening previously prepared.
N o t e : All low voltage control cables must run in separate conduit from power wires in
accordance with local codes.
N o t e : It is required that you terminate LinkPower station wiring and the auxiliary power
wiring to the ERn enclosure I/O board that will host the Paradigm Station Power
Module (P-SPM).
