Unison® Heritage AV/Serial Interface Station

Overview

The Unison Heritage AV/Serial Interface station (model# UH1AV) provides a
method for any RS232 capable device to control and interact with the Unison
Paradigm LinkConnect control network. The AV/Serial Interface Station acts
as a virtual station with similar functionality to existing Heritage station types
allowing for virtual buttons, faders and rates to be manipulated with serial
commands.

Installation

The AV/Serial Interface Station may be installed into an industry standard
single gang backbox (provided by others) or a single gang surface mounted
backbox (sold separately and available from ETC).

Installation should follow local codes and standard practices. All control wiring should be installed and
terminated by a qualified installer and should follow standard wiring installation practices. Leave
approximately 10 inches (254mm) of wiring in the backbox for connection and future service needs.

AV/Serial Interface wiring requirements include:

• Connection to the Echelon

®

LinkPower® (LinkConnect) control network utilizing low voltage
Class II wiring. Wiring is topology free and polarity independent over Belden 8471 (or
approved equal).

• Connection of two 16 AWG (1.5mm

• Connection of one 14 AWG (2.5mm

2

) wires for 24 Vdc Auxiliary Power.

2

) ESD drain (ground) wire. Required only when the

control cable is not installed in grounded metal conduit.

The AV/Serial Interface station ships with a termination kit containing a LinkPower pigtail, Auxiliary
Power pigtail, ground wire pigtail, spacers, and all required connectors for installation.

Connect the Wiring

AV/Serial Interface Station

Step 1: Pull all required wiring to the backbox .
Step 2: Terminate and connect LinkPower. LinkPower is topology free and polarity independent.

You may install LinkPower in any combination of bus, loop, star or home-run.

a: Locate the LinkPower pigtail and two WAGO cage clamp connectors from the termination

kit.

b: Strip 3/8” (9-10mm) from the ends of each LinkPower wire (both pigtail and installed

LinkPower wire).

c: Use the WAGO cage clamp connector to connect the installed control wire to the

connectorized pigtail wires provided. Open the terminal levers on the WAGO connector
and insert the installed (typically black) Belden 8471 LinkPower wire and the black lead

from the LinkPower pigtail into the terminals.
d: Close the levers onto the wires.
e: Repeat for the installed (typically white) Belden 8471 LinkPower wire and remaining pigtail

wire using a new WAGO connector.
f: Install the LinkPower connector to J4 (NET) on the AV/Serial Interface control board.

Step 3: Terminate and connect Auxiliary Power (24 Vdc) wiring.

a: Locate the Auxiliary Power pigtail and two WAGO cage clamp connectors from the

termination kit.
b: Strip 3/8” (9-10mm) from the ends of each Auxiliary wire (both the provided pigtail and

installed wire).
c: Use the WAGO cage clamp connector to connect the installed power wire to the

connectorized pigtail wires provided. Open the terminal levers on the WAGO connector

and insert the installed (typically black) 16 AWG (1.5mm2) Auxiliary Power wire and the

black lead from the pigtail into the terminals.
d: Close the levers onto the wires.
e: Repeat for the installed (typically red) 16 AWG (1.5mm2) Auxiliary Power wire and

remaining pigtail wire using a new WAGO connector.
f: Install the Auxiliary connector to J3 (Power) on the AV/Serial Interface control board.

Step 4: Terminate the ESD drain (ground) wire. This connection is required only when the control

cable is not installed in grounded metal conduit.

a: Locate the ground wire pigtail and one WAGO cage clamp connector from the termination

kit.
a: Strip 3/8” (9-10mm) from the end of each ground wire (both the provided pigtail and the

installed wire).
b: Use the WAGO cage clamp connector to connect the installed ground wire to the pigtail

wire provided. Open the terminal levers on the WAGO connector and insert the installed

(typically green/yellow) ESD drain (ground) wire and the green/yellow lead from the pigtail

into the terminals.
c: Close the levers onto the wires.
d: Install the ground spade to the receptacle on the AV/Serial Interface Station control board.
