Thanks again Phil S. Rod B

Phil S, is this what you mean? (it is from NCE Corp) I couldn't find one specifically for ZTC but the above should be Lenz (and ZTC) compatible. Rod B

Phil S is correct, the ZTC 511 has no output when set up as a slave. Rod B

Thanks all again and don't worry Iain I did notice your misinterpretation of my original post but being a 'newbie' I didn't want to immediately correct you. I do use a tethered remote with the ZTC 511 (a ZTC 622) at present but would not propose to use it with a Z21 when WIFI apps are better. Nigelcliffe makes 2 excellent suggestions - I do currently use a DPDT switch between the 511 and the track to solve the initiation voltage instability. Modern systems like the Z21 do not need this but I would have retained this anyway if still using the 511 - I would however have put it in the wrong place (between the Z21 and the track) but the correct place is between the 511 and the Z21 (thanks Nigelcliffe). I could also try using the 511 via the Lenz bus (X-bus I think), turning it to slave mode is easy enough and I must also remember to turn off the DC capabilities of the 511 - what other capabilities might this unlock?

Hi guys, thanks for your interest. I am attaching manual and spec for the ZTC 511 as requested by Iain and a diagram of the arrangement that I propose. Rod B 1272882803-ZTC-511-Manual.pdf 1277406679-ZTC-511-Data-Sheet-01mar-1097-FOR-WEBSITE.pdf

Thank you Iain and Phil for your comments. So perhaps my 'brilliant plan' was not so brilliant after all! I am going to disconnect the ZTC511 and booster from my layout and try the z21 to see how it works in the 'real world' (although I may have to limit it to 1 power district - we shall see). If I'm happy I shall probably be asking Santa for a Z21 Black and booster (with the intention of using the sniffer port to run the ZTC511). As you have probably guessed I really am keen on retaining use of the ZTC511. Has anyone had any experience of running a ZTC 505, 511 or 611 from the sniffer port of the Z21? Thanks again Rod B

Hi all, I’m new to this forum and have been ‘lurking’ for a while. I have a room sized 00 BR outline layout and for the last 15 years have been happily using a ZTC 511 + a ZTC corded remote. I recently acquired a z21 (white) from a friend and have been playing with it – I’m very impressed. I would like to set up my layout to use the z21 but want to retain use of the 511 as a (static) extra throttle, but the z21 does not have the connectivity (i.e. sniffer port). I had the brilliant(???) idea of acquiring a Z21 (black) and using the white one as a booster (my layout has 2 power districts), since I read somewhere (on this thread?) that the Roco boosters are essential the same as the Z21 master unit. Is this a good idea? Would it work OK? Would there be any conflict between the 2 power districts? Are there any other snags? Any thoughts or help would be much appreciated. Rod B Glasgow UK
