F. INSULATED RAIL SECTIONS
For best results when using insulated track rails in conjunction with the BDB. It is recommended
that you insulate the entire block. You may use a minimum of three sections (HO = 9” sections;
N = 5” sections), or more. As shown in the diagram below, remove two nickel silver rail join-
ers from one of the running rails and replace with plastic insulated rail joiners. Between the two
insulated rail joiners, solder a BDB wire (green) to one of the nickel silver joiners of the inter-
mediate track sections or replace the existing joiner with an Atlas Terminal Joiner. The wire
should be of sufficient length to reach the BDB and is connected to the TO TRK.

E. INSTALLATION OF SCB & BDB
Insulate one rail on a section of track. (See page 12 for detailed instructions.) Connect the wire
from the DET terminal of the BDB to the J5 terminal strip marked DIN on the SCB. Drill a 5/16”
hole under the signal location and drop the plug from your signal into the hole. Plug the 6 pin
signal jack into the input marked J3 on the SCB. The installation is now complete.
