2 The Retrofit 13
Verify the Retrofit
Step 1: Put the dimmer modules back in the rack in the correct/original order.
Step 2: Put the CEM3 in the rack making sure it is fully seated.
Step 3: Power up the rack.
Step 4: Check that the CEM3 powers up and the rack fan turns on. (The only rack errors
should be a lack of DMX on the ports if the DMX source is not present.)
Configure the CEM3
Step 1: Configure the rack to reflect the dimmer module types installed. Verify that the
rack type is correct (CEM3 should have determined this from the DIP switch
settings - see Backplane Settings, page 8). Configuration of the CEM3 is done
using the front face panel interface. See the CEM3 Quick Guide that ships with
the CEM3 for more information.
Step 2: Configure the data types that will be used (DMX and sACN) including the rack
patch.
