Hello All,
My new WTIU has presented two problems. Has anyone had or successfully solved the problems discussed below. Unfortunately, the users guide does not provide an MTH help desk phone number or any other obvious way to contact MTH technical representatives.
Background
I have been using 1 MTH Z4000 (first version and, currently, most recent version), 1 TIU (Rev. H2) , 1 WIU, 5 AIUs (in a daisy chain), 3 DCS handhelds, and 1 TMCC Base 1L. All of my firmware and apps are up-to-date. This combination of devices has been successfully operating DCS locomotives, TMCC locomotives and accessories, and conventionally powered locomotives and accessories. The DCS app for Android is installed on a Samsung Galaxy 23+.
Problem #1 and questions
Problem: I am trying to determine whether my WTIU is defective or poorly designed. My WTIU cannot operate more than 1 AIU. The DCS app lists all 5 AIUs. The accessories and switches listed on the correct AIUs and ports. In other words, nothing is greyed out. I systematically tested all components. After I reinstalled my TIU and WIU, the AIUs began working correctly again. See posting in this forum for details.
Questions: Has anyone else had this problem? If so, were you able to solve it?
Problem #2 and questions
Problem: The WTIU cannot connect with my TMCC Base 1L. Inexplicably, MTH does not provide a cable to connect a Base 1L and Base 3 directly to the WTIU. A forum member recommended purchasing a specific cable to connect the male serial plug of the MTH 50-1032 cable to the USB port on the WTIU. The recommended cable, however, has a male serial plug, too; consequently, I inserted a gender changer connecter between the plugs; however, the WTIU still cannot connect to the Base 1L. All of my TMCC engines appear in the DCS app, i.e., they are not greyed out. See posting in this forum for details.
Questions: Has anyone been able to connect a WTIU to a Base 1L or Base 3? If so, how? What cable did you use to connect the 50-1032 cable to the WTIU?
General comments
This has been a frustrating experience.
The quick and users guides provide incomplete instructions. For example, they make no mention of the transformer packed with the WTIU. Using the transformer makes the fixed power port input/output connections unnecessary. The instructions do not explain how to use AIUs.
The instructions should instruct users to download The DCS Wi-Fi Companion 2nd edition from MTH. The Companion explains in detail how to use the MTH Wi-Fi and app functions. The WTIU instructions do not provide detailed information about obtaining help from MTH technicians.
