Control and Data Connections
If the system includes a Panic circuit, stations or Remote Tracking Selection, pull the
necessary wires with the data cables to all required racks.
Remove the desired top, bottom or side conduit knockout from the
first rack on the left or right of the group of racks. See
data knockouts
for knockout locations.
Remove the 25 mm side data conduit knockouts between the first
rack and the other racks in the group.
Using side knockouts for data cable conduit between racks is
recommended because it provides the most direct route between
CEM3 backplanes. You can use the top and bottom openings if
desired.
Attach control cable conduit in the first knockout hole and the
knockouts between the remaining racks.
If you are installing control cable in racks that are joined together,
install IP20 rated conduit bushing into the knockout holes
between the racks
Pull DMX512 cables through the conduit
connection on the first rack and through the
connections between racks until the cable
reaches the last rack in the group. Leave
250–300 mm of slack at each rack's
backplane.
Terminate the cable(s) as shown below using
the termination kit included with the rack (in
the rack door). Refer to the guide included
with the kit for detailed termination
instructions.
Connect the DMX header to the relevant
socket on the rear of the backplane.
Only one screw header is supplied with the
rack. You may use the header to terminate
DMX A and DMX B to "PASS-THRU" if
needed.
Terminate the cable as shown below using
an IDC termination kit. Note that an IDC
termination kit is not included with the rack
and should be ordered separately.
