Data Types and Topologies
LinkConnect and EchoConnect Control Wiring
Control stations communicate with the control processor using the LinkConnect or
EchoConnect station communication bus.
Termination is available for up to six home runs of LinkConnect / EchoConnect data runs
utilizing Belden 8471 cable (or approved equal) plus one 14 AWG (2.5mm2) ESD drain
wire. This wiring is topology-free and can be installed in any combination of bus, star, loop,
and home run. The total combined length of all wire runs cannot exceed 1,640 feet (500m).
Auxiliary 24 vDC
Auxiliary power is required when you are installing certain Unison control stations. ETC
recommends using two 16 AWG stranded wires for 24 vDC auxiliary power to the control
station(s). Auxiliary power is topology-free.
DMX (Digital Multiplex)
DMX can address up to 512 channels of control. DMX is installed in a daisy chain topology
and includes one pair of wires (data +, data -) plus an ISO ground. ETC recommends the
use of Belden 9729 (or approved equal) wire with a single end of line termination (90-
150 ). For best DMX performance, twist the wires together as close to the pluggable
connector as possible.
C A U T I O N : While the wiring terminations for LinkConnect, used in SmartLink and Paradigm
systems, and EchoConnect used in Echo systems, are similar, the communication
and control types are not interchangeable. Each product family requires a
dedicated station infrastructure that cannot be shared.
N o t e : It is required that you terminate LinkConnect / EchoConnect station wiring and the
auxiliary power wiring in the same enclosure the station power module and
architectural control processor will be installed.
N o t e : It is required that you terminate DMX control wiring in the same enclosure (rack 1)
where the architectural control processor will be installed.
