Note: To enable communication from the Main Module to all of the Adder Modules, it is necessary to add a Continuity
Jumper on the last Adder Module in a chain (see the appropriate Module Settings section to verify the location of
the Continuity Jumper on a particular Circuit Adder Module). Only the last circuit adder module should have a
jumper plug on its continuity jumper; all others must be left without a jumper plug.
