Step 6: Make the power and data connections on the backplane.
a: Install the dimmer output ribbon cables. Open the black retaining tabs for each
connector until they are at a 45° angle to the backplane. Press the connectors
into their respective locations until the tabs lock in place at a 90° angle to the
backplane. 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 top of the
connector.
e: Connect the CAT5 Ethernet cable to the RJ-45 connector on the CEM3
backplane. (Not shown in the drawing below for clarity.).
