First off the WTIU is working just fine on a lot of layouts. What I am suggesting is to setup the WTIU on the bench first, before going to your layout. I am not a DCS expert in anyway but have learned some things being in IT for 43 years.
Here is a list of things I learned from OGR or I learned installing the WTIU myself.
- Setup the new WTIU system on a workbench so you can learn how it works without getting frustrated by not having your layout operational.
- Buy Barrys book on Amazon and use it. https://a.co/d/9WLqkup
- Use the system locally. Slide to "MTH" and not "Home". It just eliminates any potential issues talking to your home router. The manual gives step by step instructions for setting up the WIFI.
- Do a Factory Reset of the WTIU to level set things.
- Check the TIU firmware version. It probably needs updating. https://ogrforum.com/topic/wtiu-firmware-update
- Try a couple locomotives. Some have had ones that needed a factory reset of the engine to work clear things up to work with the WTIU.
- Here is the WTIU Manual from MTH. https://mthtrains.com/sites/de...ction/50as19846i.pdf
- With all the potential environmental issues out of the way start testing one channel at a time.
- Start with Fixed 1. The engine should get the Watchdog signal. Start it up, go back and forth, hit the horn etc.
- Do the same tests with the Fixed 2 channel.
- Set Var 1 and Var 2 to fixed. Again run the same tests.
- With Var 1 still set to Fixed, put a conventional engine on the test track. Go to the Track menu and run it that way. Use the slider to adjust the voltage to the track. Press the Direction button for a second to toggle the e-unit.
- The entire bench testing process will probably take around an hour.
- Now move everything to the layout. If it works on the bench and not on the layout, you now know it's the home router, dirty track, layout wiring and/or connections etc. Double check everything to make sure things are right. Refer to Barry's book.
Hope that helps..
