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.
