2e0dtoeric Posted January 12, 2019 Share Posted January 12, 2019 Welcome, Electrostar.First off, this post is in the wrong thread, it should be in the DCC section. I've asked the moderators to move it.Second - you don't say what controller you are using, or what update it has loaded into it. This could have a bearing on the problem, so when you reply, please include this info.There have been many reports of TTS decoders acting oddly with some controllers, so please look for and read those posts, in the DCC section.As a new poster, you will be limited to two posts for a while, until it can be seen that you aren't a spamming robot and any pictures you submit will be held for moderation, so won't appear until Monday. (The mod's only work office hours).-When you reply - please do NOT use the blue button with the white arrow, this is a repeat last post button! Scroll down to the empty white space, type your words there, and use the GREEN button with the word 'reply' on it. Thanks Link to comment Share on other sites More sharing options...
RDS Posted January 12, 2019 Author Share Posted January 12, 2019 Hi guys. I'm new to the forum and have a problem with my class 67 tts sound chip that I've fitted inside my Bachmann class 66. It's run fine for about 6 months but now it runs well at very slow speed but then when I increase the speed to slow/moderate speed it just stops moving but the sound continues to play as if it were still moving. Once I increase the speed to fast it shoots off. Any ideas? Link to comment Share on other sites More sharing options...
RDS Posted January 12, 2019 Author Share Posted January 12, 2019 @Eric- I have moved the post.- I don't know how you asked the mods to move it. We do not see the 'Reported' posts. The best way to get a Moderator to move a thread, is to add a dedicated post, suggesting that the thread is moved. One of us will see that post and of course if it is just asking for the thread to be moved, the post can be deleted as well, without spoiling any other content.- The mods do not just work office hours!- The site administrator (Adam) generally works office hours.- Thank you (and for the Blue Box sentence) Link to comment Share on other sites More sharing options...
96RAF Posted January 12, 2019 Share Posted January 12, 2019 Com mods work the clock round by virtue of being located in various parts of the world. If we kept office hours the forum would be full of spam, rather than drivel.Rob Link to comment Share on other sites More sharing options...
Fishmanoz Posted January 12, 2019 Share Posted January 12, 2019 Easy to remove spam. Just get out the key, fit it to the tab on the tin, roll up to open tin, then drop spam in the bin. Drivel - another matter entirely. It is keyless, pernicious and ubiquitous. As evidenced by this post. Link to comment Share on other sites More sharing options...
Electrostar123 Posted January 12, 2019 Share Posted January 12, 2019 Hi. Apologies for posting in the wrong section. My controller is a Gaugemaster DCC 70 black box. It worked fine for the first six months but is now playing up. Link to comment Share on other sites More sharing options...
Chrissaf Posted January 12, 2019 Share Posted January 12, 2019 A new one on me. Never come across this DCC70 device before. For others reading. it goes in series between a conventional DC Analogue controller and the track. Somehow it overlays the DC Analogue voltage with something that a DCC decoder can understand to allow sound functions to be controlled. Either that, or it is a basic DCC controller that is just using the DC Analogue output as its input power supply. The GM documentation is rather vague. Now obsolete. See GM info below:./media/tinymce_upload/09996143e124fdf6d497e5dfe4c53c32.jpg./media/tinymce_upload/8d0bc7f180e5a03b2cacf959f06e60ed.jpg@ES123What happens if you remove the DCC70 completely and restore your layout to full normal DC Analogue control. Can you now control the DCC loco movement OK using the supported default decoder 'DC Operation' function....albeit without sound functionality?.

96RAF Posted January 12, 2019 Share Posted January 12, 2019 It looks like you provide the DCC70 with a threshold voltage (3/4 max chat):from the analogue controller then this device convertes it to a pseudo DCC signsl. I presume you are controlling the lcoc speed using the DCC70 speed knob and it is likely that this is where the fault lies. It would be interesting to put a scope on the output wires to view the waveform. You could try adjusting the input voltage a tad either way and see if that makes any difference to the end controlled output. Rob Link to comment Share on other sites More sharing options...
2e0dtoeric Posted January 12, 2019 Share Posted January 12, 2019 I sit corrected - I thought that the Mod's could see the 'report' comments, and not just Admin Adam. Link to comment Share on other sites More sharing options...
Chrissaf Posted January 12, 2019 Share Posted January 12, 2019 Reading the DCC70 instructions again. It looks as if this DCC70 device is fixed to ONLY control the default decoder 003 address. That is to say it can't operate any DCC fitted loco other than address 003. Hence why it has a Shift, 9,9 routine to revert any other decoder address back to 003.
