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.
