Positioning Block Detectors for AIU-01

John Cahill
 

I have a HO layout which measures 25' X 13' in a U footprint (base is 13', legs 25') and has a new terminus station which was built with block detection wired in as it was constructed, using a mix of BD20 and HDL hdM14 4-way units.  The rest of the layout is about to be rewired for block detection but due to its physical form, fiddle-yard, two through stations and mainline runs, there will be a lot (30+) of detectors scattered across the layout.

What is the ideal way to optimize the wiring back to 3 AIU-01's?  Is it OK to have long runs back to a single base?  Should the AIU's all be in the same place? How close to the PowerPro does the AIU-01 need to be? Ultimately the AIUs will connect back to a laptop.  Obviously, avoiding interference is a priority, while minimizing wiring runs is also desirable.  Any thoughts, ideas and general rules would be appreciated. Thanks in advance,

John Cahill
