YD9401 and Digitrax Simplex


 

Does anyone know if a DR5000 upgraded to a YD9401 will work with Digitrax Simplex throttles? My DR5000 will, with some settings tweaks.

Hi Alex,

?

The YD9401 does not / can not / may not implement the closed and proprietary DigiTrax Tether less protocol.

So, sorry, won't work. You'll still u need one of those UR9x devices.

Karst,

I think you misunderstood my question. Of course a UR91 is required to receive the RF signals from a UT4R, DT400R or other Simplex throttle. My question is whether Digitrax Simplex throttles would work with the YD9401 in untethered mode (i.e. whether the YD9401 can properly receive and interpret LocoNet packets coming from the UR91)?

The DR5000 originally could not properly interpret these LocoNet packets, and when a Simplex throttle was unplugged, the slot that it was controlling, and thus the locomotive controlled by that address would behave erratically. Ryan at Iron Planet?Hobbies worked with Digikeijs to find a solution, which was to change the LocoNet baud rate to 800. I don't really understand what this does, but it made Digitrax Simplex throttles work flawlessly with the DR5000.

I know that you never had Simplex over there, as Simplex was about four years gone by the time that the EC?adopted an Implementing Decision to harmonise radio spectrum for short-range devices within the 874-876 and 915-921 MHz frequency bands.

Ah,

?

In that way :)

?

Do you mean the Baudrate-Tune option ?

That one I implemented already back in V1.4.2....

And I did it again in the YD7100 Firmware ( ported ==> YD7001 ) because not only UR91 suffer from this problem, also some old Fremo FRED controller do ;)?

?

So if @Ryan meant that Tuning option ? it's also there and will also work the same way.

And... if it doesn't I guess Rayan will be more than willing to share the sollution with me ;)

Karst,

That sounds promising! The Baud Rate setting Ryan had me change on the DR5000 is LocoNet tab>Settings and I set the Baud Rate to 800, then the Simplex throttles worked fine. The change was available in late 2021, I believe I am the first person to test all of the DT100R, DT300R, DT400R, DT402R, and UT4R with the DR5000.

So it sounds like the YD9401 should work with Simplex throttles with that same adjustment?

Thanks,
Alex

Do you mean this setting ? We have it in YD7100/YD7001 in the new "Expert" tab ;)?

Karst,

I think that's the same setting as in the Digikeijs software. If that's the case, then it should work to enable reception of LocoNet packets from the UR91.
