removing data terminations.
There are two different connectors available for CEM+ data terminations. One is
for stranded wire as found in Belden 9729 and contains screw terminals (ETC
Part# J3407- included with the kits). The other style is an IDC connector (ETC
Part# J3409 - an additional line item) for solid-core wire such as Category 5
cabling.
Transfer all wire groups (except those designated as ETCLink) to
the new connectors one at a time. Clip tie-wraps as needed to free
wires from the old backplane. See
for detailed data wiring instructions and pin-outs.
a: In most cases stranded wire has been used for the data
terminations. If so, land the DMX wiring on the new connectors in
the same manner as they were on the old backplane (physically
landed on the same connector and no need to use the DMX Thru
connector).
b: If Category 5 type cabling is used, use IDC connectors and land the rack-to-
rack jumper connections on the separate DMX Thru connector on the
backplane (J15).
If using the IDC connector for Cat5 solid-core wiring, you must start with clean wire
ends (clip the old punched end. Re-punching the old ends could result with an
intermittent or failed connection.
If present, cap the ETCLink wiring.
a: Clip the bare ends.
b: Cap the ends of the wires with the provided UL recognized heat shrink and a
heatgun.
c: Wire-tie the wires back to the cable.
d: Secure the cabling to the side or back of the rack with tie mounts and wire ties.
Complete removal of the ETCLink wiring may not be possible, and isn't necessary
if properly capped as described in
Finish removing the old backplane metalwork. Discard the old backplane.
Clip the first wire-tie behind the existing J1 power connector to give the harness
more room to move while you work.
