ETC Setup Guide
Rack-mount Repeater
LinkConnect
Paradigm architectural controls communicate with the Paradigm Architectural Control Processor (P-ACP)
using the LinkConnect station communication bus. LinkConnect is based on Echelon
LinkPower. Throughout this document, LinkPower will be referred to as the signal power on the
LinkConnect data run.
Termination is available on the rear panel of the Rack-mount Repeater for up to six LinkConnect data runs
utilizing Belden 8471 (or approved equal) and a separate connection for the repeater connection to the
DRd or ERn enclosure that hosts the initial Station Power Module (P-SPM) and the P-ACP.
Note:
ESD Ground
Architectural controls must be grounded. ETC recommends running the LinkConnect wires through
grounded metal conduit or pulling an additional 14 AWG (2.5 mm
run. ESD ground wires terminate to the provided ground bar on the rear panel of the Rack-mount
Repeater.
Auxiliary Power
The auxiliary power connector (labeled Aux Power) provides termination for up to 20 wires in the
eight-position pluggable connector. Each terminal accepts up to two 16 AWG (1.5 mm
red and black wire pair) and provides 24 VDC power to compatible architectural controls. Auxiliary wires
are topology-free. The maximum auxiliary wire run is dependant by the wire gauge and the distribution of
auxiliary load (determined per the installation). The auxiliary supply is capable is of 36 W (1.5 A at 24 VDC).
Terminate Wiring
Note:
LinkConnect
Requires a LinkConnect control run from the right I/O board in the DRd or ERn enclosure that houses the
Paradigm Station Power Module (P-SPM) and a minimum of one control run (or more as desired) from the
Rack-mount Repeater to the architectural controls (stations and sensors).
From Station Power Module
1:
Pull a single run of Belden 8471 (or approved equal) control wiring to the rear panel from the
associated right I/O board housing the P-SPM.
2:
Strip 4.8 mm (3/16") of insulation from the ends of each wire pair.
3:
Remove the two-pin connector (labeled "LON IN") from J2 on the rear panel.
4:
Loosen the terminal screws and insert the wires into the terminals.
• Insert the white (typical) wire from the pair into the "A" terminal on the connector. Tighten the
screw firmly to secure the wire into the terminal.
• Insert the black (typical) wire from the pair into the "B" terminal on the connector. Tighten the
screw firmly to secure the wire into the terminal.
5:
Replace the connector to the rear panel.
Rack-mount Repeater
LinkConnect wiring is topology-free and polarity-independent, you can install your data
runs in any desired combination of bus, star, loop, and home run. The total combined
length of the wire run cannot exceed 1,640 ft (500 m), with a maximum distance of
1,313 ft (400 m) between any two un-repeated communicating devices.
All Class 2 low voltage control cables must run in separate conduit from power wires.
