COMPONENTS
1. R21 Powered Raceway
The R21 Powered Raceway - up to 96 feet long - contains one DMX Headend (one required per universe), up to
forty-eight 20A Dual Dimmer and/or Relay Modules, and at least one Power Terminal Box (PTB). The number of
Power Terminal Boxes is determined by the location and the number of necessary power feeds.

2. Raceway Control Module
The Raceway Control Module (RCM) is used to configure the R21 Powered Raceway. The RCM comes in a 19-inch
"rack mount" configuration for local applications.
Figure 2: Rack Mount RCM Components
3. DMX Headend
The DMX Headend is a central connection point for the R21 Powered Raceway dimming system. One DMX
Headend is required for each universe. The incoming DMX universe is wired inside the DMX Headend and the
headend distributes its connected DMX universe to all dimmers, relay modules, and DMX outlets (as applicable)
within the R21 Powered Raceway chassis.

Dimmer Modules 7
R21 Powered Raceway Installation Guide
4. Dimmer Modules
Overview
R21 Powered Raceway Dimmer Modules contain one 20A dual dimmer with 20A (2400W) power shared between
the two dimmers. Each dual dimmer module includes two Focus/LED Indicator buttons, which function as both focus
adjustment controls and status indicators.
Figure 4: Dimmer Module Detail
Dimmer Module - Focus Buttons
The Focus Buttons can be used to quickly set the output level or test the module as follows:
• If the module is Off, a tap on the button will take it to full on.
• If the module is On, a tap will turn it off.
• Whether On or Off, pressing and holding the button will ramp up the intensity level. Releasing the button will hold
the setting at an intermediate level.
Note: Fixtures turned on by the Focus Button will remain on until a control console sets a non-zero DMX512 level
for the module. The module’s level setting will be cancelled and it will now follow console control. If the module is
already set to a non-zero DMX512 level by the console, the button becomes a “Flash-to-Full” control, overriding the
level only while the button is pressed.
Dimmer Modules - LED Indicators
Each focus button contains two LEDs associated that are associated with each dimmer and report various operating
conditions. The Red LED turns on for approximately 4 seconds on power-up, and after that the indications are as
follows:
Red LED Green LED Condition
Off Off Normal Operation
Off Flashing No Load
Off On Focus mode (controlled at dimmer)
Flashing
(1.5 sec On, 0.5 sec Off) Off Oversized Load or Overload

(0.5 sec On, 0.5 sec Off) Off Over Operational Temperature
On Off No Communications with Head-end Processor

5. Relay Modules
Overview
R21 Powered Raceway Relay Modules contain one 20A dual relay with 20A (2400W) power shared between the two
relays. Each dual relay module includes two Focus/LED Indicator buttons, which function as both focus adjustment
controls and status indicators.
Figure 5: Relay Module Detail
Relay Module - Focus Buttons
The Focus Buttons can be used to quickly set the relay operation or test the module as follows:
• If the module is Off, a tap on the button will turn on the relay.
• If the module is On, a tap will turn it off.
Note: Fixtures turned on by the Focus Button will remain on until a control console sets a non-zero DMX512 level
for the module. The module’s level setting will be cancelled and it will now follow console control. If the module is
already set to a non-zero DMX512 level by the console, the button becomes a “Flash-to-Full” control, overriding the

6. DMX Single Output Plate
Overview
As an option, the R21 Powered Raceway can be configured to include single DMX output plates to connect DMX
controlled equipment that may be hung with the R21 Powered Raceway, but not controlled by a dimmer or relay
module. The DMX Single Output Plate is wired directly into the R21 Powered Raceway, so additional wiring is not
required.

10 Mechanical Considerations
MECHANICAL CONSIDERATIONS
1. Tools and Supplies
The following tools and supplies will be required:
• Phillips and slotted screwdrivers
• Adjustable open-ended wrench
• Ratchet and assorted socket set
• Wire cutter and stripper
• Cable/box connectors and fittings
• Digital voltmeter / RMS
• Hammer (for terminal box knock-out holes)
Note: This is a basic list. Depending on your specific installation, additional tools may be required.
2. Installation Location
The location planned for installation MUST meet the following requirements:
•Weight Load Capacity - The R21 Powered Raceway should be installed using mounting brackets with sufficient
load capacity to support it. Choose one of six approved mounting configurations. Refer to "Mounting the Unit" on
page 12.
•Ventilation Allowance - The room must have sufficient space to allow air to circulate and cool. The R21 Powered
Raceway must have a minimum of 12 inches of clear space above it to allow for proper convection cooling.
•Indoor Use Only - The R21 Powered Raceway is rated for indoor use only.
WARNING! The unit is to be stored and operated in and environment that is at or below the following conditions -
Ambient Temperature: 32 to 104oF / 0 to 40oC with a relative humidity of 5%-95% Non-Condensing. At no time
should the unit be stored, operated, or installed outdoors.
•Dry Locations Only - The R21 Powered Raceway can only be installed in an "office clean" area that is never
exposed to moisture of any kind. Vari-Lite is not responsible for damage to equipment caused by paint, dust,
solvents, cleaning supplies, improper storage or abuse.
CAUTION: Refer to National Electrical Code® and local codes to determine whether additional requirements must
be met.

Wire Routing 11
R21 Powered Raceway Installation Guide
3. Wire Routing
Before deciding a final mounting position, consider all wire routing as follows:
• Line power wiring may enter the unit through the top or side of the Power Terminal Box. See Figure 12 under
"Line Power" on page 15.
Note: The RCM does not contain any field serviceable components.
WARNING! You must have access to a main circuit breaker or other power disconnect devices in order to install any
wiring. Failure to disconnect power before installing or servicing the unit may result in injury.
4. Wiring Requirements
• For control wire-type requirements, refer to your job drawings as prepared by Strand Lighting.
• For power wire-type requirements, refer to Strand Lighting drawings, contract drawings, and applicable codes.
Note: For assistance or questions regarding installing or connecting power to the R21 Powered Raceway,
please contact your Authorized Strand Dealer or Vari-Lite technical support at 1-214-647-7880.

Termination of Shielded Cable
To terminate shielded cable:
Step 1. Strip off specified
length of outer jacket.
Step 2. Cut shield (foil or
braid) flush to outer
jacket. DO NOT cut
drain wire.
Step 3. Fit specified length of
1/16" heat shrink
tubing over the drain
wire.
Step 4. For solder connections, fit a 1/2" length of 1/16" heat shrink tubing over each conductor.
Step 5. Fit a 1" length of 3/8" heat shrink tubing over the entire cable. Position it so that 3/4" of its length is over the
cable jacketing, and 1/4" of its length is over the loose conductors.
Step 6. Strip 1/8" inch of the insulation from each of the conductors.
Step 7. Terminate the conductors on the terminal block, or solder the terminals as specified.
Step 8. For solder connections, shrink the individual 1/2" lengths of heat shrink tubing over the solder terminals.
Step 9. Shrink the remaining heat shrink tubing.
Step 10. Apply the appropriate ID label to the cable at the end of the outer heat shrink tubing.
