That seems pretty definitive to me, and would be inline with Hornby's previous history of developing something that sort of meets the standards (XpressNet in this case) but when it doesn't they are not really that worried because they want to operate in a walled garden, which for clarity means that they want everyone to remain completely within the Hornby environment and interoperability outside the Hornby walled garden is not something that they will invest time, money or interest in.

CV8=4 followed by CV8=6 will change the the value of F03 to F06 to normal operation and CV8=3 followed by CV8=5 will change them back to logic-level.

Only other option is to speak to Roco support and tell then everything that you have tried. I have found them extremely helpful, though sometimes they can be a bit slow in responding.

If your locos lose contact on curves or turnouts then you have a problem. The reason the contacts are springy is to allow for the side to side movement and you should never lose connectivity between the wheel and the contact.

that is why I said in my earlier post to set CV3 and 4 to zero …

You can check pickups on the bench using DCC in exactly the same way that you use DC - no difference, but you may want to make CV3 and CV = 0 before you start to ensure that the locos run without the extreme inertia characteristics that are often used. I assume the second DCC statement means DC? In which case you need to read CV 29 and add 4 to the value that you read. You can check the setting by using this link. (if the value already in CV29 shows that DC running is already enabled then you would appear to have an issue. DCC CV29 Calculator (2mm.org.uk)

What is it you need to know - I don’t see any questions to answer 😞

You do not use the YDF7001 Wi-Fi, you use a wire from the YD7001 to the router and then to the rest of your network. The YD7001 only works as an Access point for phones, multimice, etc. If you want to use Wi-Fi to connect the YD7001 then you need to bridge between the Wi-Fi routers. This is what Karst and I have described.

What are you ‘bumping’ - I have you the same information that Karst sent you.

You can get a full trial licence for iTrain by asking for one from iTrain@berros.eu. You will be granted 60 days for the Professional version. After that period the licence used to revert to limited ‘free’ licence however I think that has been discontinued. The different licence versions are shown here; https://www.berros.eu/en/itrain/pricing.php

That means you have a lot of devices 'visiting' and consuming IP addresses, probably for short periods, with the result the 'residual' devices are being forced to use addresses higher up the 'stack'. I would check the DHCP Lease period and also flush the pool to get rid of dead addresses.

The signal won’t degrade but you will almost certainly suffer a significant voltage drop across the connection and if all the locomotives are at the far end of the layout from the controller they might not work due to voltage drop, or damage the connectors which are not designed to carry tyat much current.

A router doesn’t randomly assign addresses from the pool. When a totally new device requests an address a specified sequence of events happen which results in the next free address starting from the beginning of the address range is issued out. This is also issued with a lease period which is commonly 24hrs or 30 days in home routers. The next new device is offered the next address, etc. At 50% of the lease period an attempt is made to renew the lease using the same IP Address for the same MAC. If it is free then the lease is renewed for another lease period. The router keeps a list of the MAC and IP addresses that have been used, but are now free, for a period and then eventually releases them. This retention of addresses and issuing of new addresses can quickly consume the available DHCP range, especially with the number of devices in households that use IP these days. Between phones, computers, televisions, and all the other white goods you can quickly allocate 50 to 100 addresses due to the retention period. The effects of IP conflict can range from service denial to the two devices with the shared addresses to network collapse when devices use the so called ‘Smart IP’ because all the devices try to avoid each other and find there isn’t enough address space to stop the conflicts happening. This is why all routers that have DHCP allow static addresses to be issued to network devices - they don’t implement the functionality because they are nice people, they implement it because it is vital to ensuring a network operates correctly.

Even easier is make sure that the DHCP pool starts above 192.168.x.128 which is the case for many home routers. Another common pool starts at 192.168.x.64 which will require alteration. When railway IP range is 192.168.0.x-254 and the home is on 192.168.1.0-254 then you could make the subnet mask 255.255.254.0 for everything and just have one large network - but I wouldn't advise that 😉

There is no such thing as DCC ready, or even DCC turnouts. You can wire turnouts for better reliability and performance that will improve their use on DC as well as DCC - indeed many people were wiring turnouts in the manner now called 'DCC Ready' 60 years ago (and probably more, I can only vouch for 60 years) and long before anyone had thought of DCC.

IRRC ideally you need a 4p4c connector at each end with pins 1-1, 2-2, 3-3, 4-4 but you may be able to use a 6p4c connector using the centre 4 connections.

You need to use an external Wi-Fi router to enable this. You can make the SSID and password the same as the main house router. You don't use it as a router - just as a Wi-Fi enabled switch, and ideally give the LAN an address on your house network. The functionality was removed on the YF9401 upgrade because it was a significant security risk in the DR5000 that could not be mitigated and it was therefore removed to allow the wi-fi provide safe communications within the household.

@Ron Ron Ron Unfortunately a z21 doesn't have a CDE connection which is why I didn't mention it , and I don't know if NCE does.

B-Bus is not a standardised connection and different manufacturers implement it differently. There are converters available from Roco to allow connection from B-Bus to other systems such as Massoth and older LDT boosters. I also know that the Roco B-Bus works with other European boosters, such as Digikeijs DR5033 or the YaMoRC YD7403. Your other option may be to write to Roco and NCE to find out what the pinouts are for their B-Bus implementations and then create a specific cable.

It is f14 on my Zimo decoders that are factory fitted by Roco 😉

silly question - but have you checked the output from the power supply using a multimeter to check if it is the correct voltage, rather than just reading the label and assuming the voltage?

But with the TXS ‘solution’ only fitting a minority of the models on sale, plus a limited range of sounds, they are not a solution that will match the needs of the majority of modellers. The level of control offered by these decoders is also poor when compared to ESU or Zimo.

We need to see the rest of the layout to understand what polarities on on the track for each turnout. it could be that you are causing the short because the rails are at opposite polarities and you are bridging them with the loco.

The auxiliary switches are completely isolated from everything and you will not ‘see’ any voltage on them. Like any other switch you need to connect them to something for them to switch whatever it is on or off. To switch or change a frog take the left rail to one side of the switch and the right to the other and use the common output to the frog. This will then change the frog with the movement of the blades. If you get a short then you change the left and right outputs over.

I am wondering if your CAN cable is damaged - can’t really think of anything else 😒 The other people I know with one found it to be like mine - plug, switch on then run the trains. I have spoken to one and he is as lost as I am with the fault.
