DCC Specialties PSX Circuit Breaker and Digitrax AR1 Compatibility

Posted by on Aug 3, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

The Digitrax AR-1s are very slow because they are a mechanical relay, and hence keep the reverse short on the layout for an electrically long time. The PSX is fast, so it trips first. The best solution is to switch the AR-1s to PSX-ARs. Since the PSX-AR is a breaker AND a reverser, you can run it directly from the booster and still have short circuit protection AND reversing capability. The next possible solution is institute a delay in the PSX trip time. Set CV55 to 1;...

Programing Indexed Control Variables & Understanding Indexed CV’s

Posted by on Jul 24, 2015 in Tips Decoders and Installations, Tony's Tips |

CV indexing enables us to organize and store related programming functionality under one “Master” CV. The confusing part to many modelers is the fact that access to a Master CV’s programmability can only be gained through its indexes. A Master CV can have as many as two such indexes. Referred to as “Primary” and “Secondary” indexes, they are expressed as decimal places in an indexed CV’s formula. Happily, the CV numbers of the Primary and Secondary indexes remain the same,...

PSX-AR Snap Coil Wiring & Switching Polarity Automatically

Posted by on Jul 16, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

Hi Guy’s, I’m looking into purchasing 2 PSX-ARSC units but have some questions? 1) I am using Hornby 3 wire point motors (switch motors). On the circuit board you show two common terminals. Do I wire the Hornby common wire to either one of the common ports or do I need to add a jumper across both common ports? 2) I want to use the units on a reversing loop. After the train enters and travels sufficiently round the loop so that the current and the point motor...

Digitrax Zephyr and PSX-AR

Posted by on Jul 8, 2015 in Blog, Tech Specs, Tips DCC Components, Tips DCC Systems, Tony's Tips |

I would appreciate some help in setting up PSX-AR with a Digitrax Zephyr Extra DCS-51.  Here’s some of the questions. I have checked software version with LED D6 – It is version K. I understand that I should install a jumper J7-3 to J7-4 and that prevents PSX-AR from misinterpreting multiple commands Digitrax sends on startup? Does that mean that there are no “special programming instructions” for Digitrax? The manual packed with the PSX-AR is rev M...

PSX Flashes D6 LED on Start up

Posted by on Jul 8, 2015 in Blog, Tips DCC Components, Tony's Tips |

Buy PSX & PSX-AR Hi Guys, On power up, one PSX always flashes a brief D6 led before normal D7 comes on.  This happens with or without load or locos on that power district. Otherwise system operates well. Purposeful short functions and recovers normally. Is this a concern? Thank You, Larry Kedes Hi Larry, Not a problem. When first turned on, the PSX assumes there is a short on the track and has the output off (D6 is then on). Once it has successfully run through its...
