CEM3 Sensor Rack Retrofit Manual
Data Terminations
1:
Unscrew the control data connector (J2) to release it from the backplane.
Transfer beacon wires
2:
Remove beacon wires 5, 6, and 7 from the J2 connector using a precision 3/32"
(2.5 mm) flat-blade screwdriver. The wires are the beacon wires and will be
transferred to a new Phoenix connector that ships attached to the back of the new
CEM3 backplane. Carefully cut any zip ties that secure these wires to other wires
in the J2 connector or to the backplane.
3:
Connect the three wires to the new Phoenix connector in the order shown at right
using a precision 3/32" (2.5 mm) flat-blade screwdriver. Pin 1 will be the top of the
connector in the new backplane.
4:
Disconnect the DMXA wires from terminals 1, 2, and 3 of the J2 connector.
5:
Connect the DMXA wires to an 8-pin connector using a precision 3/32” (2.5 mm) flat-blade
screwdriver. DMXA wires connect to the following terminals:
• J2-3 = (DMXA common)
• J2-1 = DMXA-2 (DMX-)
• J2-2 = DMXA-3 (DMX+).
Note:
Transfer DMX Wires
When transferring wire groups be sure to transfer all wire groups (except those
designated as ETCLink) to the new connectors separately to avoid confusion.
• In most cases stranded wire has been used for the data terminations. If so,
terminate the DMX wiring to the new connectors (found in the kit) in the same
manner as they were terminated to the old backplane. Double-up the DMXA
wiring to the same terminals as the DMXA pass-thru wires. (The DMX pass-thru
connector on the CEM3 backplane will not be used.)
• If Category 5 type cabling has been used for the DMX wire runs, IDC connectors
must be used (ordered separately) for the new terminations. Connect the DMXA
wires to an IDC connector and land the enclosure-to-enclosure jumper
connections on the separate “DMX PASS-THRU” connector (J12) on the new
backplane.
DMXA PASS-THRU: Common=1, Negative=2, Positive=3
DMXB PASS-THRU: Common=4, Negative=5, Positive=6
Note:
There are two different connectors available for CEM3 DMX data terminations.
One is for stranded wire as found in Belden 9729 and contains screw terminals
(ETC part# J3407-F included with the kits). The other style is an IDC connector
(ETC part# J3409-F must be ordered separately) for solid-core wire such as
Category 5 cabling.
CAUTION:
If using the IDC connector for Cat 5 solid-core wiring, you must start with
clean wire ends (clip the old punched end). Re-punching the old ends could
result in an intermittent or failed connection.
