In the Controller mode, the DMX output has to be connected with a DMX terminator at the
last fixture in the chain. This prevents electrical noise from disturbing and corrupting the

connected across pins 2 and 3, which is then plugged into the output socket on the
last projector in the chain. The connections are illustrated below.
