10 CEM3 Sensor Rack Retrofit Manual
Install the New Backplane
Step 1: Ensure the DMX termination switches are set properly. Termination should be
turned on for the last physical rack in the DMX daisy-chain (No DMX wiring
leaves the rack from that port).
Step 2: Bend one arm of the new backplane metal in
towards the opposite arm (about 30 deg).
Step 3: Insert the backplane metal on an angle. Then
straighten it once it is past the face of the rack.
Push it into the rack far enough that it stays in
place, but leave yourself some room to make
the power and data connections.
Step 4: Make the power and data connections on the
backplane.
a: 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.
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 seated.
b: Install the power harness (Look at the pin shapes for proper orientation. It will
only fit one way.)
c: Install the DMX connections. (The wires travel out of the top on both styles of
connectors.)
d: Install the 3-pin beacon connector (The wires travel out of the bottom of the
CEM3.)
e: Connect the biscuit box to the ethernet connector on the backplane using the
1' CAT5 Ethernet cable. (Not shown in the drawing below for clarity.)
• In an SR6, SR12 and SR24, use the double-stick tape (on the box) to secure
the biscuit box to the bottom of the rack behind the backplane.
• In an SR48, use the double-stick tape (on the box) to secure the biscuit box
to the interior rear wall of the rack, behind the backplane.
Step 5: Push the backplane completely into place in the rack. Be careful not to disrupt
the power and data connections you just made. Make sure none of the wiring
becomes stressed or pinched.
