If you are just using the Select to power the track then it should not affect bluetooth decoder operations unless you are using the 1-amp PSU, the 4-amp unit is better.
If you are using the Select with the dongle to control legacy locos then the update will help.
You mean a DCC 101.
An analogue controller sends a variable 0-12volts DC to the track and any loco thereon will move accordingly. To control several locos you need to isolate track sections and have several controllers to drive trains in their section.
With DCC you make the whole track live by way of the 15v track output from a single DCC controller. This output is a kind of AC not DC in that it is a square wave bipolar waveform that carries a zero-one coding that a decoder listens to.
Each loco has such a decoder fitted which has an address to which commands are sent from the controller down the rails.
Each decoder equipped loco will only respond to commands sent to its address therefore you can have many locos on the same track each under individual control.
For further details have a look at Brian Lambert's web site linked to in the general section - handy links sticky post. Other such DCC instructional sites are available.
The dongle should take priority over host duty from the decoders. If a loco is acting as host refresh the host and the dongle will take upon the task. Having a static host host reinforces the mesh.
I have a 6th gen iPad Pro running v17.4.1
I have an iPad Air stuck at v12.x.x which is supposedly supported but cannot run the app. What will load and run the app at which version of iOS is device dependant and as Daedalus said device processor is likely the limitation not the version of iOS.
This has been covered before in the early days after the app launch.
The product page is wrong in that it shows both R046 yellow and R047 green switches as on-off. The yellow switch should be described as on-on as it says it switches signals colour to colour or a turntable from fwd to rev. The green switch is an isolating switch - on-off, so can only send the turntable one way, which when used with the controlled (speed knob) output uses the controller to switch direction.
Ignore the DCC conversion then and use either the R046 on-off switch from the controlled output of the HM2000 or an R047 on-off-on switch from the DC Aux output.
This is the instructions for wiring the R070 turntable .
Also have a read of this, which is aimed at converting to DCC but info is applicable to polarity changing for DC operation.
Why doesn't someone do the analysis by comparison. Turn them upside down and check the bogie articulation range of movement. Best guessing if its a web erroro or what ever is not productive.
In UK we refer to 3-wire mains cable as twin and earth. The live and neutral are insulated and colour coded, the earth wire is bare, but latest standards are using a green/yellow sleeving.
Ring main (power circuits) wire is 2.5mm cross section area and fixed lighting circuits are 1.5mm cross section area. Flexible mains cable is usually referred to by the amperage it carries - e.g lighting will be 5 amp, 15 amp or larger for power appliances.
We also have triple and earth cables which are used for two-way or multi-way lighting circuits - e.g. top, middle and bottom of a stair well.
Unfortunately driven by regulation, not common sense. I am sure a lot of previous members of all the brands forums were youngsters and now supposedly barred from posting. One would think a counter signature by mom-pop-guardian would suffice.
The support guides area does include both the quick start guide and the full HM7000/7040 guide. https://uk.hornby.com/hm7000/hm-dcc-guides
The full guide includes reference to the Elite type button (short press-long press) and also the Elite-Select option that is needed to get higher functions to work correctly.
The information is there if you keep looking for updates.
I use mains cable (twin and earth with just the insulated wires used) for the bus wires and twin core main flex for the droppers. Cheaper by the 50m roll from Screwfix or Toolstation. 'Model Railway' wire by the metre is terrifically over-priced.
Tweaks to do what? Auto-calibrate, choice of auto-function sounds, creep time, manual braking rate, ADCC/ABC operation, etc.
Have a peruse of the famous manual to get a feel for what the decoder can do.
