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.
