Thanks. ?This worked though I had to do it a few times, trying each of the other protocols before going back to Z21. ?

My DR5000 had

XpressNet LAN

LocoNet over TCP/IP LBServer

Dr.Command

LocoNet over TCP/IP Binary

Z21/WLANMaus

Since the “LocoNet over TCP/IP Binary” was the closest to your directions I did that first but it did not seem to work. ?I tried Dr.Command and then the LocoNet/Binary again without success. ?I then tried Xpressnet and back to Z21 using your instructions, rebooting between changes, and it started to work. ?Not sure what was up but I am in business again. The two Z21 apps I have work as does my test app I was working on a few years ago. ?So Thanks a million. ?I appreciate it. ?I have not tried my HW WLANmaus yet as they are packed away in a box somewhere.

I also got word that the YD9401 replacement module has shipped so hopefully soon I’ll have it upgraded. ?I eventually plan on getting the YD7010 and also command stations from other manufacturers (real Z21, the TCS LCC thing, the N American ESU thing, a Digitrax, and the NCE/WiThrottle bridge, as I want to test my eventual app I am working on with as many command stations as possible, trying to make it protocol agnostic as much as possible. ?Eventually I’d like to to become a complete control system with autonomous action etc but I am starting with a throttle and then expanding from there to work with controls, have a library of stuff, etc. ?While I will put it on the App Store and sell it, my goal is really for my own use and satisfaction. ?

Again, thanks for the help!
