RMweb Premium melmerby Posted February 2, 2019 RMweb Premium Share Posted February 2, 2019 Hi all Is there a way of connecting Lenz RS bus devices (occupancy detectors) to one of the ports on a Z21 (black)? Link to post Share on other sites More sharing options...
WIMorrison Posted February 2, 2019 Share Posted February 2, 2019 Keith The RBus on the Z21 is Roco Bus which may be proprietary to ROCO as very little works with it going by their blurb at https://www.z21.eu/media/Kwc_Basic_DownloadTag_Component/32-1056-648-downloadTag/default/4317ca5f/1533024979/z21-black-de.pdf The module by Bluecher is an interface to Xpressnet, though why you want that when you already have Xpressnet I am not clear. This chap got RS Bus stuff work on the Lenz Xpressnet interface, might be worth looking at? Iain Link to post Share on other sites More sharing options...
RMweb Premium melmerby Posted February 2, 2019 Author RMweb Premium Share Posted February 2, 2019 (edited) Hi Iain Expressnet is not the problem! I would like to somehow dispose of the Lenz 100 set up and find some way of still using the occupancy detectors. I have 15 of them totalling some 100+ detected blocks. They use the Lenz RS bus, as do several other systems including the DR5000 but sadly not the Z21. The query is whether there is some way of using the block detectors with something else that can communicate with the Z21 e.g. what does the sniffer bus do? The only thing that I have so far heard of is the Paco RS2PC-USB which connects them directly to a PC via the USB bus. But how would you use it?

WIMorrison Posted February 2, 2019 Share Posted February 2, 2019 Keith I wasn't suggesting Xpressnet was an issue, just pointing to a link where a chap had solved some RS Bus issues this site clarifies what I thought and alluded to, the RS Bus is proprietary to Lenz and the information on it, such is available, is as a result of reverse engineering as the spec hasn't been released therefore people wont have developed for it http://www.der-moba.de/index.php/RS-Rückmeldebus Iain Link to post Share on other sites More sharing options...
RMweb Premium melmerby Posted February 3, 2019 Author RMweb Premium Share Posted February 3, 2019 Hi Iain Looks like I'll be sticking with the Lenz system for block detection. I don't fancy replacing all those RS 8s Keith Link to post Share on other sites More sharing options...
Edwin_m Posted February 3, 2019 Share Posted February 3, 2019 (edited) Digilkeijs has an RS bus port, as well as many of the other features of the Z21. Edited February 3, 2019 by Edwin_m Link to post Share on other sites More sharing options...
