TPC

Have you measured the wheels? They are split axels and might have compressed a little bit hence the play. You can pull the wheels slightly apart if to get it to the correct wheel alignment or replace the tubing.

Page 90/ 91 of the Loksound 5 manual covers uncouplers & it settings.

If you want to use Roco's close or universal couplings (height adjustable) then Fleischmann 6575 might be the nearest one.

Have a look at the sound projects on ESU site. You might find it there including the CV list for the project.

Are you using the IP address of the DR5000 in TC or JMRI? JMRI's manual should have the steps how to set up with DR5000.

Fleischmann now only do N-gauge and Roco had to drop their N-gauge range. Roco are releasing some items of Fleischmann's HO range. The BR 70 was visually very slightly updated and release by Roco, but otherwise same as ex-Fleischmann model.

Have you tried the Z21 app on a phone/ tablet other than Apple? If you are using DecoderPro with you Z21, and your loc is working with out a problem with it, then your app is the problem. From other post on this forum it seems Apple doesn't always like to play nicely with the rest.

Have you done the configuration on the CS? You have to tell it where to look for the first block, first address.

Recalculate your CV 29 and reprogram. It sometimes confuses the decoder with long & short addresses. If set for short ,check if CV 17 & 18 reads the same default value (both should be the same), and CV 1 should be the value you have pick for the short address. 17 & 18 is you long address ( if necessary you will have to reverse calc to see what it is).

ESU 5 = CV 133 time to be bridge with PP - 0 = off Set CV 339 or CV323(micro) = 31 Zimo has something similar but will have to look it up in their manual or use DecoderPro to do the settings.

First add the loco to DecoderPro, then read the "full read sheet" on each tab or do a "read all sheets". On the function map tab you will then find the current set up of the function map. Its here where you can change/ swop F keys. The Aux output and sound slots used is also on this tab after you have read the sheet.

Or have a look at Digikeijs's DR4088RB. The DR4088RB is a feedback module designed for the Roco™ MultiZentrale-Pro™, Z21™ (black), z21™ (white) and is compatible with the Roco™ 10787. The DR4088RB is available in two versions: the OPTO and CS.

Lenz 3.6 are capable of F0 to F28. So you multimouse should work up to F20, but also keep in mind how many functions the loc decoder might have. Also with some sound decoders some of the functions only work once the train is moving with sound on. The flashing of F13+ could be a bug in the 1.04 firmware of the mouse.

1.05- main update is, loco functions now F0 to F28 and can access CV I to CV 1024. Depending on the Roco CC there is also slight changes to the read/ write of CV and POM (write only).

The 192.168.0.100 is the IP address the router assigned to the tabs to use. https://www.z21.eu/en/downloads/manuals Near the bottom of the www page is the pdf for the router configuration. If you home PC is already on the 192.168.0.1 - 255 range, unplug the network cable of your PC and plug it in to the TP-link router and follow Iain's steps. If not, the pdf will guide you in setting up your PC, connect to the router and setting up the Wi_Fi. Another option is if your PC is on the 192.168.0. range and using a static IP, plug the z21 directly in the PC, and then use the maintenance tool. If not on .0. and you not sure how to create a static IP, the first page of the configuration pdf shows how. On the first screen of the tool change the IP if necessary and click connect. If the port is open the 4 tabs will expand to 7 if the port is open. If the port is locked it will ask on the first tab for the unlocking code. There is another pdf on the download page that will guide you in getting an unlock code that is linked to the router. The last tab has the programmer which you can use to reset the locos to factory default. You could also connect the z21 directly to your home router, just like to the TP-link, as long as the router is on 192.168.0.1. Rest of the steps for phone/tab apply. Have you tried the app on another phone/ tab?

M R when you get a vanilla z21 the LAN port is locked. Once you have an unlock key the port is opened via a PC & the maintenance tool. in your case it is already opened and even the reset you have done won't reset the port. I had to do it 2 weeks ago and the Lan port stayed open, but turned out the problem was the network cable. Currently there is only one Z21 app for both phone and tabs. I've change phones a few time and never had to put in a activation code, only the z21 IP address. Have you reset the router? Could be that it was set up to only accept certain mac addresses and ignore the rest. You need to connect to Wi-Fi side of the router - open tabs Wi-Fi, find the router's Wi_Fi on the list , select, enter password, if it is the first time. Just like you would log on to any other network. If possible show a photo of how you have connected the z21 & router? Serial no only via maintenance tool.

Factory IP address for a z/Z21 is 192.168.0.111. On the app you need to have the same IP address as the z21 (setting/Z21 settings/ IP address). Once connected the little bar at the top right of the screen will flash (standby) or be solid (power on) blue. If you want to reset it to factory specs keep the power button in for 5 seconds (if owner change the IP address). It will then flash purple to indicate it has reset. Use either Z21 app or the Z21 Maintenance tool (PC). https://www.z21.eu/en

Under /download/manual there is 2 pdf explaining the ports of z21/Z21. A comparison table is at the bottom of the models page. The z21 can do programing but is share the track port. Either install a switch to switch between your tracks or remove all locos from track before programing.

Verify if your version of motor shield require wire between some pins (think it is 2 and 13) and which traces need to be cut. Also some of the motor shields looks like the one prescribed for DCC++ex but doesn't work because some feed back circuit is missing. Have a look around the DCC++ forum. You can also re-calculate CV 29 to your requirements. On very odd occasions it does it own thing with addresses.

Vignale you have created a short where you have connected you grey wire. Grey and the orange wire goes to the left & right motor connection tabs of the motor. The soldering tab just above to the right of the motor tab ( mirror of your orange wire connection) is for the grey wire. Orange looks like it is on right place. The wheel sets that is not connected(probably the top set on your photo) directly to the chassis, that wire goes to the red wire. You can connect the black wire to where the grey was as that is connected to the other wheelsets (bottom set) via chassis. If you want to switch between overhead & track then solder the black wire to the solder point just above where the grey wire is now. Normally on a live chassis you don't use the blue wire as it does the same work as the black wire. If you isolate the lights , then you use the blue wire. Not clear what is going on in the top left corner of the light board, screw broken off, missing? That is the connection point for your lights (positive side). If not connected with a screw, then you will have to use the blue wire for the lights.
