A Brief History in DCC: Inrush Current

Posted by on Jun 25, 2015 in Tips DCC Components |

Courtesy of Mark Gurries NCE DCC Site Sound equipped locomotives have presented challenges to DCC that were not anticipated when the NMRA specifications were written.  The problem is the amount of capacitance that needs to be charged up to allow the sound electronics to function reliably with various types of DC power that is NOT pure DC.  The capacitor charge current is a huge spike involving amp levels that far exceed the current capability of the DCC boosters.  But it...

PSX-AR Test

Posted by on Jun 11, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

  The following tests the functionality of your PSX-AR. If you are using the PSX–AR unit on a Digitrax system, make sure you have the the Special Digitrax Configuration Enabled by jumping J7-3 to J7-4. Remove the PSX–AR from the layout and connect it directly to the booster. Turn on the booster. The PSX should turn on with both D12 and D7 indicating power and D6 off. Now take a piece of wire and connect J1-1 to J2-3. Nothing should change. Now connect J1-1 to...

PSX Test

Posted by on Jun 11, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

The following is a simple test of the PSX to make sure it is functioing properly. 1) Turn on DCC power to the PSX. 2) Verify D7 and D12 are ON and that D6 is off. 3) Connect a wire from J2-1 to J2-2. 4) Verify D12 is ON, D7 is OFF, and D6 is ON. You may see D12 and D6 pulse OFF periodically (VERY short time), this is the automatic reset. 5) Remove the wire from J2. 6) Verify D7 and D12 are return ON and that D6 turns...

Jack Wabbit: Combining the User Friendliness of NCE and Reporting Power of Digitrax

Posted by on May 12, 2015 in News, Tech Specs, Tips DCC Components, Tony's Tips |

If a Jack Wabbit is going to be used with snap coils, we add a capacitor to the board to provide extra energy to operate the coils. In this version, the Jack Wabbit will operate snap coil OR stall motor machinse on an output by output basis. You set a CV for the snap coil outputs so the Jack Wabbit knows which is a snap or stall motor. There is a high energy version of the Jack Wabbit. If you order this version, we change the power supply to double the voltage to the snap...

Trains Longer Than a Reverse Loop

Posted by on Apr 15, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

PSX-AR & OG-AR I have an OG-AR on a Wye. My trains are longer than the leg of the wye the OG-AR is wired to. Your  instructions say to cut  another set of gaps at both ends of the reverse sections in side of the original gap. The distance between these gaps and the original gaps should be about 1/2″. My question is, How do you wire the sections? Thanks for you help, Frank S Hi Frank, you don’t wire them. They are dead. The extra gaps are only necessary if...

PSX-AR Pushbutton Turnout Control

Posted by on Apr 15, 2015 in Tech Specs, Tips DCC Components, Tony's Tips |

Buy PSX-AR Here DCC Guru Larry Maier shines some light on turnout control. Hi guys. I have your PSX-ARSC, and it worked great on a loop of my layout from 6 years ago. I now have a new layout with a wye to turn locomotives. I want to have manual turnout control on the PSX-AR leg to manually flip the points after a loco drives onto that short tail track of the wye. In your updated instructions on your website, your pushbutton control directions say it takes 3 wires and 2...
