The Retrofit
Preparation
1: Use Sensor Configuration Editor and an SLTA (Serial LonTalk®Adaptor) if you want to download
and save the current Sensor configuration out of the enclosures for later reference. For
information on this process contact ETC Technical Services (see
Help from ETC Technical Services
on
page 2 ).
2: Turn off main power to the enclosure(s).
3: Remove all of the dimmer modules above the CEM (if retrofitting an SR or HSR 48 enclosure,
remove the eight modules below the CEM as well). Note and document the modules’ order/
positioning in the enclosure for proper insertion and configuration later.
4: Use a digital voltmeter to verify that power is “Off” by checking voltages for all combinations
between the phase bars, neutral and ground.
5: Remove the CEM from the enclosure.
WARNING: RISK OF ELECTRIC SHOCK! Enclosures without an accessible power disconnect
device cannot be serviced safely. Before removing dimmer or control modules
for service, de-energize main feed to enclosure and follow appropriate
Lockout/Tagout procedures as described in NFPA Standard 70E. It is
important to note that electrical equipment such as enclosures can present an
arc flash safety hazard if improperly serviced. This is due to available large
short circuit currents on the feeders of the equipment. Any work on
energized equipment must comply with OSHA Electrical Safe Working
Practices.

Remove the Old CEM
1: Mark the edge connector of each dimmer output ribbon cable (1, 2, 3, and 4) as illustrated below
in the hexagons. There may be stickers on the ribbon cables already; however, these may refer
to cable length and not dimmer outputs. They should not be used as a reference for these
instructions.
Note:
The order/layout of the dimmer output edge connectors is different on the CEM3
backplane.

2: Document and/or label each wire that is currently landed on the J2 edge connector.
3: Unscrew the dimmer output edge connectors from the backplane metal.
4: Remove the ribbon cables from the cable clamp immediately above the CEM. For SR or
HSR 48 enclosures, also remove the ribbon cabling from the clamp immediately below the CEM.
5: Carefully feed the dimmer output ribbon cables through the backplane.
6: Examine each ribbon cable for any nicks or cuts that may have resulted from scraping against the
backplane.
7: Unscrew the power edge connector (J1). Remove it from the backplane by sliding it out of the
notch in the enclosure and carefully pushing it through the backplane metal. This connector will
be used in the upgrade.
8: Unscrew the backplane metal from the enclosure. (There are two screws total—one screw in the
upper corner of each side.) Discard these screws. Replacement screws with thread locker are
provided (ETC part# HW377) for later use.
9: Push the backplane toward the back of the enclosure to free the backplane side tabs.
10: Bend the sides toward the center (out of the sides of the enclosure).
11: Slide the backplane metal forward as far as the wires allow in order to allow easier working space
while removing data terminations.
Note:
If the power edge connector is damaged, the power harness will have to be replaced.
Contact ETC to obtain a replacement CEM3 harness.

Data Terminations
1: Unscrew the control data connector (J2) to release it from the backplane.
Transfer beacon wires
2: Remove beacon wires 5, 6, and 7 from the J2 connector using a precision 3/32"
(2.5 mm) flat-blade screwdriver. The wires are the beacon wires and will be
transferred to a new Phoenix connector that ships attached to the back of the new
CEM3 backplane. Carefully cut any zip ties that secure these wires to other wires
in the J2 connector or to the backplane.
3: Connect the three wires to the new Phoenix connector in the order shown at right
using a precision 3/32" (2.5 mm) flat-blade screwdriver. Pin 1 will be the top of the
connector in the new backplane.
4: Disconnect the DMXA wires from terminals 1, 2, and 3 of the J2 connector.
5: Connect the DMXA wires to an 8-pin connector using a precision 3/32” (2.5 mm) flat-blade
screwdriver. DMXA wires connect to the following terminals:
• J2-3 = (DMXA common)
• J2-1 = DMXA-2 (DMX-)
• J2-2 = DMXA-3 (DMX+).
Note:
Transfer DMX Wires
When transferring wire groups be sure to transfer all wire groups (except those
designated as ETCLink) to the new connectors separately to avoid confusion.
• In most cases stranded wire has been used for the data terminations. If so,
terminate the DMX wiring to the new connectors (found in the kit) in the same
manner as they were terminated to the old backplane. Double-up the DMXA
wiring to the same terminals as the DMXA pass-thru wires. (The DMX pass-thru
connector on the CEM3 backplane will not be used.)
• If Category 5 type cabling has been used for the DMX wire runs, IDC connectors
must be used (ordered separately) for the new terminations. Connect the DMXA
wires to an IDC connector and land the enclosure-to-enclosure jumper
connections on the separate “DMX PASS-THRU” connector (J12) on the new
backplane.
DMXA PASS-THRU: Common=1, Negative=2, Positive=3
DMXB PASS-THRU: Common=4, Negative=5, Positive=6
Note:
There are two different connectors available for CEM3 DMX data terminations.
One is for stranded wire as found in Belden 9729 and contains screw terminals
(ETC part# J3407-F included with the kits). The other style is an IDC connector
(ETC part# J3409-F must be ordered separately) for solid-core wire such as
Category 5 cabling.
CAUTION:
If using the IDC connector for Cat 5 solid-core wiring, you must start with
clean wire ends (clip the old punched end). Re-punching the old ends could
result in an intermittent or failed connection.

The Retrofit 9
6: Using the permanent marker, mark “A” on both ends of the DMX connector.
7: Disconnect the DMXB wires terminal 3, 9, and 10 of the J2 connector.
8: Connect the DMXB wires to another 8-pin connector using a precision 3/32” (2.5 mm) flat-blade
screwdriver. DMXB wires connect to the following terminals:
• J2-3 = DMXB-1 (DMXB common)
• J2-9 = DMXB-2 (DMX-)
• J2-10 = DMXB-3 = (DMX+).
9: Using a permanent marker, mark “B” on both ends of the DMX connector.
Cap ETCLink Wires (if present)
10: If your enclosure has an ETCLink connection, disconnect the link wires from terminals #11–14 of
the J2 connector.
11: Secure wires as follows:
a: Cut all bare ends from the link wires.
b: Cap the wire ends with 3/16” (5 mm) heat shrink (fold back or pinch end of heat shrink while
still warm to seal end).
c: Coil the wires into a neat bundle and secure with a zip tie.
d: Secure the cabling out of the way of the enclosure with tie mounts and zip ties as needed so
it does not interfere with normal enclosure function.
12: Finish removing the old backplane metalwork. Discard the old backplane.
Note:
Wire runs for ETCLink are abandoned in the enclosure and can be used in the future
as DMX wire runs in the event that a DMX line must be replaced for any reason.

10 CEM3 Sensor Rack Retrofit Manual
Attach new power harness
1: Clip the first zip tie, attaching the power harness to the enclosure, behind the existing J1 power
connector to give the harness more room to move while you work.
2: Install the power adapter harness to the edge connector (straight thru PCB) and then to the old
power connector (be sure the wire colors match on both sides of the joined connectors).
3: Secure the power connectors together with the provided 4" (102 mm) zip ties. Clip the zip tie
ends for neatness.
4: Center the provided 4 1/2” (114 mm) x 2” (51 mm) diameter heat shrink
tubing over the power harness connectors (leaving at least 1 1/4” (32 mm)
past each connector).
5: Contract the heat shrink using a heat gun.
6: While the heat shrink is still soft, secure both ends using one of the provided
zip ties on each end.
7: Tuck the power harness connection bundle between the bus bar and the enclosure wall.
8: Route the green ground wire behind the bus bar, between the enclosure wall and existing wires,
and land it at an open terminal on any existing grounding bus in the enclosure using a square
drive or Phillips screwdriver.
9: Use a zip tie to secure the ground wire to the wire bundle as it protrudes from the heat shrink.
CAUTION:
A butane torch is not acceptable to shrink the large heat
shrink. You must use a heat gun.

Connect Dimmer Output Adaptors to Dimmer Output Cables
1: For each of the ribbon cables (1, 2, or 4 depending on your enclosure type), connect the
transition card edge connector to the ribbon cable.
• Pin 1 of the enclosure ribbon cable is marked by an arrow on the connector, which
corresponds to an arrow on the transition card at J2/pin 1.
2: Sit the adapter in the plastic protection box.
3: Fit the cover of the plastic protection box by snapping the lid on.
4: Plug the end of the upgrade cable into the correct header on the new backplane.
Note:
The red stripe on the enclosure ribbon cable and the red stripe on the upgrade cable
do not align. They are on opposite sides.
Match the arrow on the enclosure
ribbon cable connector to the
arrow at J2/pin 1 on the transition
card and be sure the proper side

Terminate Ethernet Cable (if installed)
1: Terminate the Ethernet cable with the provided Cat 5 Termination Kit (ETC part# 4101A2003).
Follow the wire preparation and termination instructions included with the kit.
2: Using a network cable tester, verify the connection and cable performance between the newly
installed cable termination and the patch bay, or the location where the cable terminates.
Backplane Settings
Upgrade kit backplanes ship from the factory with all DIP switches in the off (down) position. Set the
DIP switches on the new backplane to match your enclosure and verify the termination switch settings.
1: Set the DMX termination switches for each port to "Off" unless the port is the last position in
the DMX chain.
• If there are both DMX In and Thru connections to the port, the enclosure is not last in the
chain. DMX Thru connections can be made either using two pairs of wires in one terminal
block, or using the DMX Thru connector.
• If there is only one set of DMX wires in the connector and the DMX Thru is not used, the
enclosure is the last in the chain.
• If there is no DMX wire connected, leave the termination switches off.
2: Using a dental pick or other small-point tool, set the DIP switches to match your enclosure type
according to:
• Number of modules (6, 12, 24, or 48)
• Whether the enclosure has Advanced Features (AF)
Use the following chart to determine your required DIP switch settings:
DIP Switch Number

The Retrofit 13
Install the New Backplane
1: Ensure the DMX termination switches are set properly. Termination should be turned on for the
last physical enclosure in the DMX daisy-chain (no DMX wiring leaves the enclosure from that
port).
2: Install the dimmer output ribbon cables/transition cards. Open the black retaining tabs for each
connector until they are at a 45° angle to the backplane. Press the transition cards into their
respective locations until the tabs lock in place at a 90° angle to the backplane.
3: Bend one arm of the new backplane metal in towards the
opposite arm (about 15°).
4: Insert the backplane metal on an angle. Then straighten it
once it is past the face of the enclosure. Push it into the
enclosure far enough that it stays in place, but leave yourself
some room to make the power and data connections.
5: Make the power and data connections on the backplane.
a: Install the power harness. (Look at the pin shapes for
proper orientation. It will only fit one way.)
b: Install the 3-pin beacon connector. (The wires travel out
of the left-side of the CEM3.)
c: Connect the biscuit box to the Ethernet connector on the
backplane using the 2’ (60.9 cm) Cat 5 Ethernet cable.
(Not shown in the drawing below for clarity.)
• In an SR or HSR 6, 12, or 24, use the double-stick tape (on the box) to secure the biscuit
box to the bottom of the enclosure behind the backplane.
• In an SR or HSR 48, use the double-stick tape (on the box) to secure the biscuit box to the
interior rear wall of the enclosure, behind the backplane.
d: Install the DMX connectors.
e: Push the backplane completely into place in the enclosure. Be careful not to disrupt the
power and data connections you just made. Make sure none of the wiring becomes stressed
or pinched.
Note:
The order/layout for the cables is not the same as on the old backplane (see
illustration below). Make sure the proper side is facing up on each connector and
that each connector is fully and properly seated.
Note:
Clean the painted metal surface as needed for proper adhesion for the biscuit box.

6: Insert the backplane tabs in the sides of the
enclosure.
7: With the tabs fully inserted in the sides of the
enclosure, pull the backplane towards the
front of the enclosure to line up the screw
holes in the upper side corners.
8: Install one screw with a sleeve in the upper
corner of each side of the backplane.
Transfer Panic Wiring (if present)
If the enclosure had a panic connection in the previous backplane configuration, terminate the panic
connections to the new backplane.
1: Locate the wire pair for the panic connection.
2: Cut and strip 3/16” (5 mm) of insulation from the wires.
3: Connect the panic wires to the “PANIC SEND” and “PANIC RETURN” terminals.
4: Move the panic configuration switch (to the right of the terminals) to the appropriate position:
• NO for Normally Open contact types
• NC for Normally Closed contact types
Change out the AF Cards (if present)
If your enclosure supports Advanced Features (AF) you will need to replace the AF cards as well.
AF cards are located on the right side of the dimmer module slot between the copper load terminals
and the dimming circuitry cards, behind the modules in slots four through six of each group of twelve
slots.
To replace the AF cards:
1: Remove the old AF cards by flipping the white retainer
tab on the cards into the down position.
2: Pull the old cards out of the slots.
3: Set the DIP switches on the new cards according to the
chart below. Only the first two DIP switches are used.
4: Slide the new AF cards completely into the vacant slots starting with card #1 in the top. The
number of cards depends on enclosure size.
Note:
You cannot use the old screws without the additional shoulder-sleeve as they will
block the CEM3 from being fully inserted.
Note:
Flip the white tab up for the card to fully seat.

Change out the Beacon PCB
1: Remove the two screws that hold the beacon PCB in the face of the enclosure.
2: Pull the PCB down from inside the enclosure case. (The
wire harness will only allow a few inches of movement).
3: Note the orientation of the connector and unplug the
wire harness from the old beacon PCB.
4: Attach the wire harness to the new beacon PCB,
making sure the connector is in the same orientation as
before.
5: Install the new beacon PCB (ETC part # 7141B5109)
with two screws (ETC part # HW222.) (Three new
screws of the same type are provided in case the old
ones were damaged during the removal process.)
Enclosure Door
1: Remove the old Sensor beacon acrylic in the door and discard by loosening the two retaining
screws with a #2 Phillips screwdriver.
2: Install the Sensor3 beacon acrylic in the door with the
longer edge toward the center of the door.
3: Carefully peel the old Sensor label from the front of
the door and discard.
4: Clean the door surface to remove any dirt or old
adhesive. Ensure that the door is completely dry
before continuing to step 5.
5: Apply the new Sensor3 label to the front of the door. Line up
the label to the top of the enclosure door and be sure the
label is straight. Press and wipe with the removed paper
backing to make sure the label is flat and smooth and
properly adhered to the enclosure door.
6: Repeat the above steps for all retrofitted enclosures.
Note:
Be sure to use a properly sized screwdriver (#2 Phillips) and a good amount of force,
because these screws are kept in place with thread locker. Don’t worry about
damaging the existing screws (replacements are provided) or shearing off the heads
of the screws (the screw shanks are threaded into the PCB’s standoffs).

Verify the Retrofit
1: Put the dimmer modules back in the enclosure in the correct/original order, making sure all
dimmer circuit breakers in the enclosure are turned “Off.”
2: Put the CEM3 in the enclosure in Test Mode (enabled using the switch located on the right hand
side of the PCB).
3: Power up the enclosure.
4: Check that the CEM3 powers up and the enclosure fan turns on.
5: Check that the signal lights on all dimmers are illuminated. If not, power down the enclosure and
verify CEM3 and all ribbon cables are fully and correctly seated.
Configure the CEM3
1: Change CEM3 from Test Mode to Normal Mode (enabled using the switch located on the right
hand side of the PCB).
2: Configure the enclosure to reflect the dimmer module types installed. Verify that the enclosure
type is correct. (CEM3 should have determined this from the DIP switch settings. See
Backplane
Settings
on page 12 ). Use the front face panel interface to configure the CEM3. See the CEM3
Quick Guide
that ships with the CEM3 for more information.
3: Configure the data types that will be used (DMX and sACN) including the enclosure patch.
4: Program and verify Panic (if used).

Note:
If AF cards are present, it may take some time for them to fully load their software.

deemed hazardous e-waste by some municipalities. Please dispose of in accordance
with local requirements.
