Decoder pro cant read decoder

AD All Messages By This Member #240313 I have a Athern model big boy model 22900 dcc w sound #4005. I cant read the decoder with digitrax or decoder pro on programming track. i would like to try on the main. i put engine on mainline. First i cant choose mainline programming. So i put an engine i can read on the programming track ,read it, select main line programming. Shut off decoder pro. Turn on ? I don’t know what decoder it is so i choose the decoder manually using sound train tsunami -steam and get many to choose from so i pick one at random to open a programming window and go to the motor page. I enter a long address and try writing. ?Get message it cant find a loco on the main but its there and power is on. ? please tell me how to get this one cv changed on the decoder.. ? i cant read the decoder type when on the main ? please list a procedure ? also does anyone know what decoder is in this engine. also same for challenger model 22923? ? tony

(Programming on Main) Place your Lok on the programming track and do new decoder, followed by read type from decoder. read the main page to get the Lok address. Find the pages with stuff you want to change and read those pages t00. (All is best if you have the time) Save that as roster entry. The you can go to POM and select that roster entry, which has the address and other data. You can now program everything except the address with POM. -- --- Thomas DeSoto, TX
AD All Messages By This Member #240322 开云体育 Sorry but placing the engine on the main and selecting new loco then ‘read type from decoder’ gives a message that there is no loco on the main line. I can run the engine on the main using address 3 but the decoder pro cant find it. That’s the problem i am trying to solve. How does decoder pro find the engine?

AD All Messages By This Member #240323 开云体育 Sorry i misread your message. I did place the Athern big boy on the programming track and selected new loco and read the decoder. Got no response and error message about an acknowledgement. Thus i cannot determine what decoder is in the engine. So i use another engine and have decoder pro identify its decoder. I then select programming on the main and put the bigboy on the main. ?I write the long address to the decoder and get message that there is no engine on the mainline. So what do i now do Tony toggle quoted message Show quoted text On Mar 6, 2025, at 7:43?PM, thomasmclae via groups.io <mclae5-lists@...> wrote: ? First no reading with POM.

Marc N Fournier All Messages By This Member #240326 First off, no DCC System will READ on the Main without additional hardware. Second These Athearn engines used the older Tsunami decoder and they require a Program Track Booster (PTB-100) to READ on the Program track other wise they will fail on the READ. There is no ACK involved in a WRITE on MAIN, so your last error indicator makes no sense ( no engine on Main ) as the system does a blind write on the main. Marc
AD All Messages By This Member #240327 That means decoder pro is looking for the engine on the programming track when it’s on the main . The ‘program on main’ is selected but whited out. Since i cant read the decoder i cant get the decoder pro to select ‘program on main’ using the big boy. Yes it’s an old tsunami decoder but decoder pro lists many versions of that decoder under the title of steam engines and a bunch of different steam engines.. Do you know what version is in the bigboy and the challenger Tony toggle quoted message Show quoted text On Mar 6, 2025, at 10:31?PM, Marc N Fournier via groups.io <forfoum@...> wrote: ?First off, no DCC System will READ on the Main without additional hardware.

Phil G All Messages By This Member #240328 开云体育 While not impossible, it’s VERY challenging to correctly change addresses on the main. Best avoided at all costs (you can easily end up with your loco misprogrammed!) Set the address ON THE PROGRAMMING TRACK, then you can do everything else on the main Phil G toggle quoted message Show quoted text On 7 Mar 2025, at 01:35, AD via groups.io <bklyns_baseball_club@...> wrote: ?

Mick Moignard All Messages By This Member #240329 开云体育 You can’t read decoders on the main. You must use the program track.? What command station are you using? This loco probably has a Tsunami-1 decoder, which requires a program track booster like Soundtraxx’s PTB-100 with older Digitrax command stations. ?You’re not using a DB150, by any chance? ?That one doesn’t have a readable program track at all.

Not quite. I own a commercially-available DCC command station which _can_ read mobile decoder CV values "On the Main" from _some_ mobile decoders _without_ additional hardware. Owned it for a few years. There are some other DCC command stations, by different manufacturers, which can do so, too. But _all_ of these systems have limitations for allowing "Programming on the Main CV Reads", including: . Those command stations can support "reading of mobile decoder CVs On the Main" from only certain types of mobile decoders. Some of these solutions only support reading of mobile decoder CVs On The Main when using the DCC system manufacturer's decoders using its special electrical signaling. Other solutions support a different electrical mechanism that is aligned with the NMRA's optional "RailCom" feature. If the mobile decoder does not support the required electrical signaling solution, then the decoder cannot be "read" using the command station's special hardware which can otherwise support CV Reads when performing "programming on the Main". - Those command stations can support "reading of mobile decoder CVs On the Main" when the supported decoder decoder is on a chunk of track that is powered by the command station's DCC Track outputs. If the mobile decoder is located on track powered by a different "booster", it will (probably) not be readable "on the main". - Those command stations can support "reading of mobile decoder CVs On the Main" when the supported decoder decoder is configured to allow Programming on the Main "Read" access. If the decoder supports the Programming on the main Read" feature, but has it "disabled", then the mobile decoder will not be able to perform "programming on the main reads". Other restrictions may apply, like "certain manufacturers' decoders put so much electrical interference onto the DCC track signal that they can prevent Programming on the Main CV Reads from working reliably to _other_ decoders". In this case, it may be necessary to remove those badly-behaving locos from the command station's trackage when trying to perform Programming on the Main CV Reads. FYI - I believe that at least _some_ Tsunami mobile decoders _can_ have their CVs "read" via "Programming on the main" with a certain manufacturer's command station hardware. Check with SoundTraxx and the command station's manufacturer for confirmation.

Decoder pro list of decoders under soundtraxx tsunami steam has about 4 choices and many sub-choices in each of those. ?Can you possibly look at it and guess which one is in the old big boy Tony toggle quoted message Show quoted text On Mar 7, 2025, at 3:55?AM, Mick Moignard <mick@...> wrote: ?You can’t read decoders on the main.
