Hello, I now have my layout to the point where track is laid, trains are running, and I need to start looking at detecting trains in what will eventually be...
... pricey. For true occupancy detection you need to measure current drain to the track circuit, much the same as the prototype does. You can use inductors or...
Hi Tim, CMRI is PERFECT for what you want. All you really need to light LEDs on a panel is a DCC0D and have the section electrically blocked. The DCCOD can...
Group: I would agree completely with Earl and add to his comments that some of the detection methods may not see the entire train. Diode and coil detectors...
... Usually, a small magnet is mounted on locomotives, away from the couplers, so the two won't interact. Locomotives are massive enough that they won't be ...
Hi Tim, I just helped a friend with this exact problem on the JMRI users group. JMRI PanelPro will be able to do it and you do not need any programming...
Earl, Your last paragraph on the reed switches and the magnets have given me a
possible brainstorm idea to implement on our 2 Walthers Cornerstone
turntables...
For proximity detection it would work fine. The reason I went to a 3/4" long magnet is so that it would work on a pilot, which is not necessairly centered...
If understood the question a simple detection method was desired. Either of the CMRI detectors offer a simple reasonable priced solution. One thing that needs...

While I understand that you need at least the last car to draw current if you want to know where the beginning and end of the train are, my initial feeling is...
With that requirement forget the resistor wheel sets and just use the either of the CMRI BOD boards and the LED panel. David Metal NMRA Life Member Gramps...

My SMINI says a block is occupied or at least it is grounded on the 6th input pin. The DCCOD does not show occupied unless there is an engine actually in the...
Group Has anyone tried doing the Passenger Terminal Design of Fig 9-11 and code of Fig 9-14 of the user manual? Don Wood has been helping me with it but it is...
Jay Remove the IO cables and run the wraptest on the SMINI to verify all inputs are operating. Then you know if you have a hardware problem in the SMINI or a...
That was my next step so I will do that and see what happens. Thanks Don Jay Beckham Berkeley Springs, WV Visit My Web Pages www.CruisesOnTheSea.com ...
Don I did as you suggested and found that the SMINI was good. Now pin 1 and 6 are showing as active (grounded).. Those pins (1-24) are connected via a RJ45...
Seems like you narrowed it down to a problem with a ground path behind the motherboard or a solder jump on the MB or you have a short on the wire from the MB...
Don I did some more testing and it seems the fault is the DCCOD detector. I moved the two around and the problem followed. I suspect the problem is the Q1...

Don I also checked Jameco and Digikey. Jameco has them and only two kinds, one RoHS approved and the other not approved. Digikey had a dozen or so and I...

John and Don I tried testing the transistor on the board by using a VOM from the Base to the Emitter and from the Base to the Collector according to some...
By all means get a few spares - they are inexpensive and will save lots of trouble - spending 5 minutes replacing a $0.10 part is faster and easier than...
You can just do a diode test on the transistor base to collector and base to emitter. I have two or three customers that have an emergency kit of snips, spare...
