Don’t look too hard for your glasses, there is no mention of mma/jna run 2 in oo gauge on the projects list.🙈

But of course functions such as sound on/off, volume up/down do not actually require a sound channel. You need 1 channel for the basic sound, which is linked to the speed, Then there is whistle/horn but only one variety at a time. You many need a compressor or cylinder drain cock Then possibly shovelling. But I struggle to get to more than 5 or 6 at once.

How many channels do you really need. If you try to trigger a number of sound by the time you get to the last one then the first has finished. A number of the sounds are not compatible on a number of sound projects. E.g flange squeal and coupling Bacon frying and shovelling coal Short and long whistles or horns, some projects have more than 2 varieties. I am not says 3 is the best number but so far I have not come across any sound project that needs 10 at the same time. There may of course be sound projects that could benefit from a large number.

So are Bachmann doing the same, items on backlog some for years that have not arrived yet and items only announced if a quarterly announcement that have arrived in the same quarter. Are those being prioritised. Meanwhile back in the land of HM7000……..

If the video you were looking at is the q&a that took place this week then there was a section where they demonstrated an HM6010 to control points from the HM7000 app.

The secret of the HM7000 documentation is as follows. Hornby.com Support Product support Instruction Manuals See all sections Additional manuals The sound details are under the Profile Function Maps

In the recent Hornby video on the HM7000 they said that the TT models were making noise that affected the sound. From what was said I believe the issue is with the motor control, e.g. the PWM. This probably needs to be different for each type of motor. TT models obviously cannot use the same motors as the OO models. For the same reason they may be issues with different varieties of motors in the OO models, e.g X04, Ringfield and different types of can motors. There also may be issues with motors in non Hornby models. Issues also exist for other sounds. E.g. chuff. The chuff rate is dependant on the speed of the main driving wheels. The only control that the decoder has is of the power provided to the motor. The motor characteristics will vary its speed based on the power supplied. There is a relationship between the speed of rotation of the motor and that of the driving wheels, that is based on the gear ratio’s between the two. This means that there will more than likely need to be changes to the motor control and it’s relation to the sound of the chuffs. And of course the TT models will be different to the OO ones. Again this is an issue with other manufactures models as they will use different motors and different gearing. But fundamentally the sound itself will be the same whatever scale it is.

Hornby have updated the sound profile availability list as at 31/3/23 https://support.Hornby.com/hc/en-gb/article_attachments/8280166052892/Available_Profiles_for_HM_DCC__31-3-2023_.pdf It now gives dates for the sound previously announced but not yet available.

Does the lack of support for Railcom on the HM7000 decoders cause issues if used on a DCC system that has railcom in use. Apart from of course the lack of detection.

I think that sound for models not currently in the range was more about models that were previously in the range but they did mention a class 68 manufactured by another maker. They did show an elite with some sort of adapter that allowed two legacy dongles to be connected to the one rj12 socket so two separate app devices can control DCC models at the same time. they are still testing the legacy dongle and this may include other expressnet devices from other makers. it may be possible to run the android version of the app on windows 11 or chrome books using the android app capability. no solution to connect the dongle to the Elink so unlikely to be possible to use the app to control DCC locos, but the elink can be used to run models with rail master and to provide the power for Bluetooth controlled models. looking at using the app in landscape mode to allow two locos to be displayed and controlled on the same screen.

Sound quality was poor, at least one of their mikes did not seem to work. They did not know the current limits of the decoders, 1A continuous, 1.5A peak according to the reference manual. The two speakers were the sound designerand the app designer, decoder guy not present. Android at least a month away. Legacy Dongle Q3/4 HM 6000 to be included in the App. HM6010 demonstrated with app. TT to be added to the layout section of the app, but no date International model sound being considered but no dates. May do sound for models not currently in range.

Has anyone tried the Legacy Dongle. What is it capable of, e.g how many decoders can it control simultaneously. What DCC systems have you tried it with, Hornby say Elite/Select but no guarantee for any other Expressnet controller. No docs that I can find on the Hornby site.

Just a cable with the correct connectors for the Hornby 15v PSU.

Correct CV1. Short address CV17/CV18. Long address CV19. Consist address all have no function when using the Bluetooth control from the App. Hence you cannot use them to control the decoders or consists, I.e control more than one decoder. You can use the App to set these values however. You would then need to switch the HM7000 decoder to DCC operation and use a standard DCC system/cab’s to control the decoders. This of course means that you would need to have DCC signals on the track, I.e you could not use a DC controller or simple PSU to power the track You can set these

In the app click on settings (cog) and then profiles. You do not need any linked device to do this

Are the guides you are talking about the Sound Profiles Function Maps, because those are basically just a list of the functions. Hornby have made a mistake by putting all the HM DCC documents in the Additional Manuals section of their web site and not a section on its own like the HM DC section. I guess that this miss filing may be difficult to fix now.

I think I saw somewhere that there were going to be separate documentation for the sound profiles. The reference manual has generic information for the decoder and sound types but nothing specific. Have the documents been produced, and where can I find them, assuming there are such things. Particularly I am interested in both versions of the HST sounds, and also the Class 800 (sound profile not available yet but is on the original list). Decoders in these models need to operate in pairs. Do they need to be in a consist. Can you set one decoder to operate slightly differently, e.g. start delay, horn only from front car in the forward direction etc. The TTS decoders only operated as two identical units. The reference manual does not help. Added the following As far as I can tell, the Bluetooth control can only talk to one decoder at a time. Therefore consisting, top and tail, double heading are all currently not possible using the app. other than treating the two loco’s as separate items. But there will be issues if both loco’s have motors. I have not tried yet but somethings may be possible e.g. consist or multiple decoders with the same address should be possible using a DCC controller. I.e. just using the DCC and not Bluetooth. It looks like the best you can current do with the app is to turn the lights on etc on the rear dummy loco, and then switch to controlling just the front one. You would then need to switch between loco’s to alter settings, e.g switch lights.

AJ’s asked in the DCC section about the blank area of the decoder and whether it could be cut off. The Mod locked the topic and pointed everyone back here So to answer the question is NO you cannot remove the extra bit of the decoder as it contains the Bluetooth Aerial. If you look at pictures of the decoders in some you can see the wavy line. Cutting it off would disable the Bluetooth.

I would say NO. The sound decoders come with a default sound for an A1/A3 which is not the best. The default settings of a numbers of CV will be set for the same loco. Trying to auto-calibrate the BEMF will produce erratic results. Without the App you cannot change the sound profile or the loco profile, plus of course you cannot use the Bluetooth capabilities. But you can set CV’s and run the loco from any DCC system. I think that a lot of people have ordered the decoders hoping that by the time that they arrive then the App will be available. Some are reporting that the Apple IOS version will be available shortly, but the Android version will take longer. You can also find out if the APP is available by checking on the appropriate App Store, search HM DCC.

Certainly all the pictures of the 8 pin also have next18 printed on them. But there must be something other than just the connector that is different. The 8 pin one is quoted as 4fn and the next 18 is 6fn. If there was no difference then someone would come up with a way to wire the extra 2fn. But the App would appear to be able to distinguish between the two, so no point as the extra two function would not work as the firmware would not allow it.

I am getting the same error. Re pricing ok trunk items. I suspect that to keep things simple Hattons have to charge VAT on items added to the trunk, until it is actually shipped to an eligible address then the VAT cannot be deducted. If they took the VAT off earlier it would then be an issue if the Item was shipped to a address not eligible for the VAT deduction. But of course this would be a problem for non UK residents as the initial charge would include VAT.

As with most new things there are issues with the documentation. E.g. CV1 is in the range 1-127 in several places and then 1-128 in others. But of course with the manuals online Hornby can easily put that right. There are other places in the documentation where information is not available and this is also easily fixed. There is quite a cost of putting documents in the box, both in term of printing cost and the extra shipping costs due to added weight. That is the reason that most suppliers are putting all the documentation online except for the equivalent of a quick start guide. Please can members report issues with the documentation or requests for clarification to Hornby..

Have you changed any CVs. By default the decoder will have settings specific for an A1/A3. The motor, gearing and wheel sizes will be different for the models that you have tried and hence things like the acceleration and deceleration will be wrong as well as start and max voltages. The NMRA defined CV’s will be the same as the standard, and any other compliant decoder, so documentation from any source can be used. In fact even if you install the decoder in an A1/A3 then you would need to download the latest profile, as the default is going to be out of date, and will not work “perfectly”. The default profile would have been loaded into the decoder several months ago and things will have changed since then.

So if Hornby release the decoders before the App then there will be an awful lot of layouts with A1/A3’s on them and some funny looking steam loco’s that run on diesel. However it would help Hornby’s cash flow rather than having the decoders waiting on shelves in their store.

There is only one part number (R) for each of the decoder interface types, so you cannot buy a decoder with a specific sound project loaded. If one of the sound project is loaded by default then there is less than a 1 in 30 chance of it being the one you require. Therefore it might as well be blank.
