Re: Bus suppressors - extremely hot!
The necessity of snubber depends on the booster design. They are more commonly needed on NCE boosters than Digitrax due to design trade-offs in the booster design. I didn't think they were supposed to slurp up that much current though?

Those TCS throttles are great. Very user friendly and easy to set up.

Iain,
This exact topic has come up repeatedly in the MRH forum. While European model railway exhibitions are more dense than American train shows, train shows here are nonetheless notorious for breaking proprietary radio systems- yet Wi-Fi is extremely robust and quite reliable. In fact, in my experience, and the experience of many others with modular layouts, Wi-Fi itself is more reliable than temporary setups of Digitrax LocoNet, NCE Cab Bus, or other similar wired connections. I know of several large modular model railroads that use NCE and don't run Cab Bus at all, and instead rely entirely on NCE Radio and Wi-Fi. Where Wi-Fi can be problematic is things like accidentally?unplugging power cords, laptops going to sleep, etc, but once those things are all ironed out, and a stable setup is used, Wi-Fi is extremely robust.
That being said, at train shows, there is a lot of usage of the 2.4ghz ISM band, and I would not rely on a command?station's built-in Wi-Fi, a dedicated Wi-Fi device like the LNWI or WFD-30, nor on a Raspberry Pi. All of them have relatively weak Wi-Fi that's not going to handle interference as well as a dedicated router.
Lastly, even if everything is working properly with a wired throttle network, you still don't have control while you're hunting for the next plug to plug into, whereas with a Wi-Fi throttle network, as long as you set up the Wi-Fi network properly and don't let your batteries die, you have control.

For those that have been asking when will my book be out or just want something tangible, my book is now out!
?
This book explains the basics of DCC systems and components, provides guidelines for choosing and installing a system, and shows how to install and program decoders.
?
It can be purchased wherever you have purchased Firecrown Media (formerly Kalmbach Media) publications.? Here is a link for Trains.com with more on the book:

Bus suppressors - extremely hot!
I have recently installed two DCC Concepts Bus Suppressors on my layout. I have 2 power zones, each supplied by a Digikeijs Digiboost, with one suppressor on each zone.
?
I use a track feed from a Z21 black connected to the sniffer input of each Digiboost.
?
As soon as I power up, both suppressors get very hot to the touch, is this supposed to happen ?
?
Many thanks

Re: Loconet compatibility with DR5000 and YD7001
It was a Digitrax BXPA1 Loconet DCC Auto reverse with detection.
It excepted the board I.D. ok. But never reported occupancy high or low over Loconet.
This was monitored with the jmri Loconet monitor and also the Loconet feedback monitor on the YD7001. Railcom is off on the YD7001.
?
When the unit was returned the dealer tested it with a Zepher and it worked ok.

Re: Loconet compatibility with DR5000 and YD7001
No problem, can happen ?
?
But I start to be curious WHAT did not work, and WHICH module we are talking about.
As i wrote below, it IS known that some/many Digitrax modules cannot cope with RailCom Cut-Out being present in DCC and/or RailSync.
Greets,

Re: Loconet compatibility with DR5000 and YD7001

Sorry about that I used the wrong word it was meant to be software update.
?
It was daisy chained with YD6016LN/YD6016ES. These all work ok. I tried different cables and tried the unit directly into the YD7001 to no avail.
?
Thanks

I beg your pardon ? :O
What's the logic when replacing the Network module (with no link whatsoever with LocoNet), any hardware LocoNet problems would/should/must be "solved"....
Mostly "some every other time"? message of stuff not working ( no I don't keep track of them ) was either solved by turning-off RailCom on the DR5000/YD7001 or change the DCC wire polarity...

Loconet compatibility with DR5000 and YD7001
?I have just spent hours trying to get a Digitrax reverse module to report occupancy via Loconet. It works correctly with a Digitrax command station. Luckily, I was able to get a refund on the module.
I now find out this is a known problem with Digitrax Loconet items not working correctly DR5000 and YD7001.
I thought the whole idea of Loconet net was you could buy any Loconet item and it should work.
?
Shouldn’t this problem have been solved with a hardware update to the YD7001?
?
Also a list of incompatible items would be very handy?

Re: Problems between YD7001 and Windigipet 2021 Premium
Dear all, good evening.
?
My colleague tells me that now the problem is with the turnouts. When he starts a route, the program starts to change the turnouts but for example, if he has to change 6 turnouts, he only changes 3 of them and of course the route fails. When you tell the program to start the turnouts, you don't move all of them. This didn't happen with the DR5000. What can it be?
?
Thanks for your help.
