I have the very nice Lodi-Con Controller ()....that was advertised to work with any Z21 protocol station. The unit has huge potential but there seems to be one issue, and the company that makes it blames Roco and a bug in the Z21 protocol. To get it to even function you have to set it to ignore data coming from the command station and only send data. This means some of its features don't work (like acceleration and deacceleration) which is a shame. I wonder if Karst knows anything about this? Is this something you can fix for the YD7001?
Heres the message from the manufacture:
?
yes, I'm aware of the YD7001. However, it also just uses the official Z21 protocol, so it doesn't matter whether it's a Z21, YD7001, MD, or any other control unit with the Z21 protocol. For example, our LoDi-Rektor can also use Z21, and it doesn’t work there either because the speed steps get mixed up in the protocol, and the response from the control unit differs from what the handheld controller has set.
?
Yes, that's exactly how it's intended to work in LoDi-Con, and it also works with Ecos, LoDi, CS from M?rklin, and Lenz. However, as mentioned above, the problem with the Z21 arises here. The control unit sends back only garbage to the handheld controller, hence the inconsistency.
