? ? ? ? ?I have a DR4018 installed on my layout with the signal inputs connected to my main buss line and temporarily the power inputs are daisy chained from the signal inputs. I have a DPDT Center Off toggle switch installed on my layout with 1 set of connections to my DR5000 and the other set of connections to an MRC Controlmaster 20 DC power pack. The center connections are connected to my main buss line. With this setup I can switch the whole layout between DCC and DC, one system at a time. I do this because I can test run and break in DC locomotives before adding a DCC decoder to them.?My question is since the DR4018 inputs are connected to my buss line, will switching the layout to DC power damage the DR4018 in any way ? Will I need to disconnect the DR4018 before applying DC power to my buss line ? Thanks in advance for your help with this matter.
