Fitting HM7000 8TX Runs Different Direction to Normal

[JohnH]

I’ve searched the forum without success so thought I would start a new one.

I bought the Hornby Dublo Flying Scotsman as 60103 and fitted a new HM7000 8TX sound decoder. It works great but the direction of travel is opposite to what I get with my usual RailMaster / Elite setup. I checked that I put the chip in the right way so that’s not the problem.

Is there a setting that I can change on the HM7000 to change the direction of travel?

Really simple, on the app go to advanced cv settings, scroll down list to cv 29

tap on the ‘1’ to change , tap exit, you have now reset the direction of travel. Hit the refresh arrow to ensure they are updated on the decoder and app

Thanks Rallymatt

I did the following without success:

Click on Locomotive Settings

Click on Adv CV Editor

Moved down to CV 29 and selected it

It had item 2 selected

I clicked on this to stop that and clicked on 1 to select that

Clicked on Exit

It showed Value 1 next to CV 29

I hit the refresh arrow and it said it had updated

However the direction has not changed.

Any further help would be appreciated.

There have been reports before about changes made in DCC mode not sticking.

Ignore bit ‘2’ set it back how it was. The direction is controlled by bit ‘1’

repeat the process and update.

The listed numbers in the CV represent ‘bits’ these are activated (lit) or deactivated (unlit) effectively turning the switch on or off. The numbers of the bit are arranged in such a way that the the total can only mean a particular series of on/off events for each ‘bit’ the app does all these calculations for you, all you need to do is highlight or turn off the particular ‘bits’

Do it again and shut down the loco for at least 60 seconds and shut down the App and restart having done the refresh 😁

Sorry. I’ve done exactly as you said and the direction still hasn’t changed. The 1 & 2 are highlighted under cv 29 in the Adv CV Editor giving a value of 3. Any other suggestions?

Go and have a look at the post Bluetooth (CV29) which is exactly the same problem.

[Rallymatt]

Clearly something else going on, or rather not going on, so best to wait now and see what the boffins come back with. It should be a pretty easy operation normally.

[JohnH]

Just to say that I double checked again that I had put the chip in correctly. It was put in correctly and there is still the issue. I await the boffins as you say.

Hi. There was an update when I used it a couple of days ago. The problem seems to have been resolved. Thanks to all.
