Section 2 The Retrofit Preparation Step 1: Use the Sensor+ Connect web interface to download and save the current configuration out of the pack for later reference. Instructions on saving your configuration from this interface can be found in any CEM+ Software Release Note or any CEM+ Configuration Manual available for download from the ETC website (www.etcconnect.com). Step 2: Disconnect all of the Cam-Lok® connectors and data connections from the portable pack.
Remove the CEM+ Backplane Step 1: Remove the lid retaining bolts using a wrench (may be 7/16” or 3/8” depending on your pack model). The bolts are found at the top of each side of the pack, just beneath the lip of the carrying handles. Up Side View of Pack Step 2: Raise the lid from the data connection side to expose the CEM+ backplane. Step 3: Disconnect the multi-colored DMX ribbon cable and CAT5 cable from the backplane. Step 4: Remove the lid entirely to expose the inner cavity of the pack.
Replace Phase A Bus Bar A slightly modified Phase A bus bar is included in the upgrade kit. This new bus bar allows for greater clearance between the bus bar and the CEM3 backplane. You will need to remove the old Phase A bus bar and install the new one in its place. To remove the old bus bar: Step 1: Note: Disconnect the Phase A Cam Wire and Phase A Detection Wire using a #2 phillips screwdriver or socket (may be 7/16” or 3/8” depending on your pack model) as required.
Attach New Power Harness The upgrade kit contains a power wire harness adapter that will connect to the old backplane power connector. Step 1: Connect the power wire harness adapter to the old power connector. The connectors are keyed and will only fit together one way. Make sure the connector seats firmly and the retaining clip snaps in place on the adapter. Step 2: Leave the green ground wire running out of the pack; you will connect it to the CEM3 backplane in a later step.
c: Secure the ring connector to the backplane using the 6-32 x 1/4” screw with lock washer (ETC part # HW213) from the upgrade kit. It may be necessary to raise the backplane out of its location in order to tighten the screw. Connect ground wire to this location using screw and washer from kit Step 4: Secure the backplane in place using the new screws and collars provided in the kit.Screw holes are in the top corners of each arm of the backplane.
Backplane Settings Upgrade kit backplanes ship from the factory with all DIP switches in the off (down) position. You will have to set the DIP switches on the new backplane to match your pack. You will also have to verify the termination switch settings.
Install New Pack Lid and Reassemble Pack A new pack lid with the appropriate beacon board and Sensor3 sticker is included in the kit Step 6: Place the new Sensor3 pack lid partially in place and in the upright position over the output connector side of the pack. Step 7: Connect the new DMX ribbon cable to the blue connector on the rear of the backplane and to the DMX connector on the beacon board in the pack lid.
Step 12: Place the pack side rails back into their original locations and secure them with the 5/32” allen screws removed earlier. three screws top and bottom, for each side rail (24 screws total). Be sure to put the side rail with the door hinge screw holes in the appropriate location, opposite the door latch retainer. Place side rail with door hinge screws holes in this location. Door latch retainer Step 13: Attach the new door to the side rail using the screws removed earlier.
