    Hello,
    Need guidance on getting Digitrax BD4 to work with DS64. Am using N scale Kato Unitrack with JMRI, Decoder Pro.

    I am unable to have the DS64 switch with input from BD4. Have wired pin 1 from DS1 of BD4 to input A1 of DS64, exactly per the schematic provided by Digitrax. Have also wired pin 2 from BD4 to the AX1 terminal on DS64, all 3 pics attached.

    I know the BD4 is sensing the locomotive because the particular section LED on BD4 glows when the locomotive enters that track detection section and stops glowing when it leaves that section. But the DS64 does not switch. Have tried with the switch thrown either way to begin with.

    The DS64 switches just fine when it’s operated using Decoder Pro. It being a small layout, the DS64 is powered directly with track power, with no aux power input.

    Am I missing something? The DS64 OpSw setting is in default mode. Does a particular OpSw setting needs any change for DS64 to sense input at A1? Is there anything in the wiring that needs to be changed…?

    Regards
