SPECIFICATIONS
GENERAL External Processing Rack (ER4) houses the
architectural control processor and
option modules
Provides architectural lighting control for Unison,
Sensor, and other DMX512 dimming racks
Ambient room temperature: 0-40˚C / 32-104˚F
Ambient humidity: 30-90% non-condensing
All racks UL and cUL LISTED
MECHANICAL 18 gauge formed steel panels
Fine-textured, scratch resistant, epoxy paint
ER4 may be wall mounted, or rack mounted
when installed with the Rack mount kit (RM 5C)
Top, bottom, and side knockouts facilitate
conduit entry
Full height hinged locking door
No tools required for module removal
or installation
Front access to all wiring and terminations
ELECTRICAL External Processing Racks are available in
100-120, 230 and 277 volt, single phase
configurations.
Completely pre-wired by the manufacturer
Designed to support the following
wire terminations:
AC (single phase)
Echelon Link Power
24VDC
DMX512 In
DMX512 Out
RS232 Serial In/Out
Category 5 UTP(CMEi only)
Multi-Mode Fiber Optic with ST Connector (CMEi only)
Contractor supplies the input and control wiring
All control wire terminations are terminated
via the factory provided connectors.
CONTROL CME – Control module with station processor

CMEi – Control module with station processor
VARIANTS
and network connections
The CM contains a nine button membrane
overlay and a two line by 20 character LCD for
system configuration, testing and diagnostics.
The architectural station processor (E) accepts
Echelon Link Power control signals from the
Unison control stations and remote interfaces.
The Link Power network utilizes a polarity-
independent, low-voltage Class II twisted
pair wiring.
Belden type 8471 (unshielded) or Belden 8719
(shielded) or equivalent and (1) #14 ESD drain
wire (drain wire not required for systems
installed in metal conduit).
Network wiring may not exceed 1500’ (500m)
without the use of a repeater (REP). The repeater
option module increases network wire length
in increments of 1500’ (500m).
Control wiring terminates in the ER rack via
provided connectors.
Architectural station processors require a Light
Manager system configuration
Station configuration and program information
are stored in non-volatile flash memory.
A 3.5" floppy disk drive is used to facilitate
loading of station configuration into the
system processor. (CME & CMEi)
CMEi control modules allow connection to
an Ethernet network for system configurations
and monitoring, via Cat 5 or Fiber Optic
The architectural processor controls 512 dimmers,
512 zones with 32 wall stations - 4 LCD
stations maximum.
A Repeater option module (REP) may be
used to increase station count in increments
of 32.
OPTION Option modules are housed in a formed steel
MODULE body and require no discrete wire connections.
Tool free insertion and removal
Option module variants include:
REP – Repeater Option module, which provides:
Repeated Link Power and 24VDC control power
Adds 1500’ (500m) to the total potential wire run
Powers additional 32 wall stations
Powers 4 LCD or PC interface stations
AIR – Airflow Option modules are required for
any empty option module space in the
ER4 enclosure.
ACCESSORIES A 19’ rack mount kit (RM 5C) also available
