Re: turnout frogs within a reversing section
开云体育Disagree. ?TV Hexjuicer can be used as an AR if connected to both rails. ?But if used only to juice the frog it does not affect the “phase” of the AR segment and works just as it would within a non-AR segment. ? Fact that the frog juicer is within an AR segment is irrelevant. ?Bill D N&W Steam Only On Jul 9, 2023, at 1:09 PM, Don Weigt <dweigt47@...> wrote:

Re: turnout frogs within a reversing section
Isn't the frog juicer just a specialized autoreverse? If so, putting one or more in a track powered by an autoreverser violates the rule of not connecting two to adjacent tracks. I'd suggest you contact Tam Valley about it. They have the most to gain by making it work, and the most information about it. Whether the frog juicers are powered from the normal rail power or the autoreverser's, it seems to me both will see a short circuit, and that triggers a race: the thing that makes different autoreversers on two adjacent blocks not allowed. I hope Tam Valley has a solution. Don W -- Don Weigt Connecticut |

Push Button Panel not sending DCC code to JMRI Wiring Help Needed
Hello
I have a Yard with 17 turnouts? all using DCC Concepts Cobalt IP Digitial. motors? ?I have a NCE System that run my DCC system. ?I have dwarf signals on each turnout using NCE Light-its. I am running JMRI 5.5.1 on my Windows 11 laptop. I also have a Button board using a momentary push button that has a red and green LED.? ?(Mouser Electonics?107-PS001-N11NAWURUG) On my JMRI Panel all the turnouts are setup as monitoring? this way when the turnout changes the icon on the turnout goes from green to red. then back to green if changed again. On my panel the LED changes from green to red also. From my Power Cab I select Assy 142? (thats the address of the Cobalt IP)? then select 2 to open the turnout.?? The Push button for 142 changes to Red My JMRI Panel showing 142 changes to RED? After engines passes thru I then change 142 to closed? the Push Button for 142 goes green and my JMRI panel goes Green. Now when I push the button for 142 the turnout changes the LED on the Push button goes RED? But my JMRI Panel showing 142 still shows Green. So the DCC code for 142 changing was never sent to JMRI The push button?107-PS001-N11NAWURUG? has 4 pins? 2 for the LED and 2 for the Push button The two pins for the push button goes to the cobalt ip pins 9 PSB-R and 7 PSB-L PINs 1 and 2 on the cobolt IP connect to my DCC Bus Line for that section of the layout. Pin 3 is connect to my Frog on the turnout Pins 4 s2-L? ? 5 s2-R? ?and 6 s2-C? are connected to the LED on the Push button and a DCC Concepts DCP-SPS12 12 VDC Power Supply Pin 6 to the LED pin on the push button? the other pin on the LED goes to the DCP-SPS12?? Pin 4 and 5 on the Cobalt IP go to the DCP-SPS12 I have? diagram of this but not sure how to post that on here. Since? JMRI need two way traffic from the turnout? how can I get this to work I was working with my JMRI friend and he is not a electrical engineer? and he suggested I get a micro switch and place it on the throw bar on the turnout He also suggested I connect the cobalt IP pins 4 5 and 6 to an NCE AIU -01? on the cobalt IP pin 6 S2-C would go to the ground pin on the NCE AIU-01 and pins 4 and 5 on the cobalt ip would go to pins 1 and 2 on the AIU-01? that would be two sensors setup The NCE AIU-01 would send the DCC code to JMRI and then the turnout on the panel would change. The push button would still work because the push button is connected to the cobalt Ip pins 9 and 7 ?The only thing I and not sure of is how to wire up the LED using a micro switch. The micro switches are something I never worked with. we found this one on mouser electronics? ? ? D2F-01L?Any ideas or suggestions how I can get the push button to work properly? Thank you Tom -- Tom Grassi trgrassijr@... |

Re: turnout frogs within a reversing section
开云体育The frogs within the AR segment should have their own frog juicer or be powered through the servo throwing the points, just as in in a non-AR segment. ??Bill D N&W Steam Only On Jul 7, 2023, at 6:41 PM, William Waithe <wwsd40@...> wrote:

Re: Lining multiple turnouts within a yard ladder.
Touch toggles sound like switches that hold their position. If so, how will they get cleared or released when the next touch toggle is activated? You need something momentary, because you don't want the previous ones to stay closed when you press a new one. What you described was functionally the same as a 16 position switch, where each position selects one track and deselects all the others. Something will have to store the last button pressed until the next one is pressed, then automatically be released. Then, you can decode which tortoises need to be in which positions for the latest button push, and hold those outputs until the next button is pushed. Alternatively, you can decode the combination of normal and thrown turnouts needed immediately, and latch all 15 or more tortoise drivers to hold those states until set to new ones by the next button push. I'm not familiar enough with the hardware you specified to know if it could do the job. Back in the day, diode matrices were frequently used for this. If you have a latching driver for each tortoise, then a diode matrix might be used to set them as needed. Of course, there are many ways to do it, including relays, microcontrollers, programmable logic, a bunch of simple logic ICs wired appropriately, and so on. What you or an assistant are most comfortable with will determine what's best for your use. But, this is a rather big logic array, with 16 inputs controlling probably 15 tortoises, or more if you have multiple tracks in or extra crossovers or redundant routes. Looking at using programmable logic, any DIP IC with 16 inputs and 15 or more outputs plus power would probably be in a 40 pin package, which is 0.6 inches wide and about 2.08 inches long. It might be easier to program a 40 pin microcontroller to do the job than to try to use a programmable logic device (PLD) that essentially mimics a big programmable diode array and some latches. If you only have one signal for each tortoise from the logic, indicating which position each tortoise should be, there still will need to be driver circuitry for each tortoise to convert that one on-off signal to provide power of two polarities to drive it both ways.

Re: Lining multiple turnouts within a yard ladder.
Hi Michael,
I have no experience with this particular board, but since you're into Touch Toggles, you might want to check this out. I'd email Kevin Hunter with your use case and see if his product works. It's likely not going to give you all of the features that Tom mentions, but it might be worth an email. Have fun! Dan |

Re: Lining multiple turnouts within a yard ladder.
Michael,
I have similar setup? I am using a NCE System? ?and tortoise machines I have a button board I designed with push buttons that had a Red/Green Led in them? I also I a NCE Mini Panel?? I also use tortoise machines. In the Mini panel you can setup a macro to change the turnouts by the push of one button and then I have another button on my panel that resets all the turnouts in the yard. That is another macro in the mini panel They are simple to setup. Also if you have an NCE system you can create a Macro on your power cab and sett up to change the turnouts? ?I have a few macros in my power cab? ?they also are simple to setup. Need any help let me know. -- Tom Grassi trgrassijr@... |

Lining multiple turnouts within a yard ladder.
I am building a single ended yard with 16 tracks. One of those routes has nine turnouts that must be set to properly select that route. All turnouts will be powered with Tortoise Switch Machines. I would like to use Berrett Hill Touch Toggles. I believe this can be done using NCE Switch8s (and Button Boards?). Restating what I want: I want to touch a Touch Toggle on the yard schematic and have all of the turnouts align for that yard track out to the yard lead. If you have experience doing this, or thoughts on how to do this, I would greatly appreciate you input. Thank you, Michael Boyle |

Re: Same booster for reversing section and entry points to the section?
开云体育Yes!? ? The reversing module will be connected to a single booster and will flip the polarity when a short occurs at the gap.? You’ll get unpredictable results and otherwise may cause damage if the reversing section is on booster 1 and the other side of the gap is on booster 2. ? From: [email protected] [mailto:[email protected]] On Behalf Of wyantj01@... ? On another thread I believe I saw a recommendation that a reversing loop and the adjoining reversing loop entry point track should be powered from the same booster. ?Is this correct and what is the rationale? |

On another thread I believe I saw a recommendation that a reversing loop and the adjoining reversing loop entry point track should be powered from the same booster. ?Is this correct and what is the rationale?
As background I am running O Scale and currently have an NCE SB5 booster and will be adding a second SB5, configured as a dumb booster. |

DB200+ Off Line LED unusual indication
I posted this to the Digitrax IO Groups also, sorry for the duplication, but I want to ge this in fron of as many eyes as possible. "Here’s a strange problem we have at the Amarillo Railroad Museum. We have a portion of the layout powered by a DB200+, and the off line led is glowing, We have totally disconnected it from the layout, including no LocoNet connection, it is only receiving input power from a Digitrax PS2012 set to HO scale, We have switched out the DB300+ with two identical DB 200+ boosters and the off line led glows regardless of the DB200+ used, It makes no difference if the PS2012 slide switch is set to N, HO or O/G scale. We see a steady 18-volt input from the power supply, we get zero on the output side, regardless of the booster we use. It seems that the problem must be from the input, but why? What is going on?"

Re: AR1 turntable problems
Lawrence, I'm glad your problem is solved! It's your railroad. If you're happy with it now, that's fine. But, if you reversed the wiring of blocks 31 through 40, to match that of 10 and 29 you wouldn't need the AR at all, which is even better, IMHO. Why rely on added electronics when it's not necessary? It will never be quite as reliable as wiring without it... Don W -- Don Weigt Connecticut |

Re: AR1 turntable problems
Thanks to all for the info you have provided me up to now.
It turns out that the issue was maybe a dirty pot on the AR1 CURRENT TRIP, but I have adjusted it and there are NO issues any longer. I did NOT change any rail polarities and it is working as it did previous to my "problem". The Auto Reverse does exactly what it was designed to do, not requiring any radial rail to be polarized based on the split ring A and B sections. Thanks again. Vic |
