Eric,
I agree part of the problem is with the app error routine, it doesn't actually tell you what it doesn't like, " No TIU found" is a useless message, because in actual fact it can be found because it runs the other engines !
No, that's not the problem at all. The problem is that the WIU simply cannot see a TIU, period. It's up to you, not the app, to find the cause.
Typically, this is due to one of the following:
- The cable connecting the TIU and the WIU is defective or otherwise inappropriate.
- The WIU and the service hosting the DCS App aren't properly connected via WiFi.
- Mismatched software levels in the app, the TIU and the WIU.
Further, you haven't provided any information regarding your layout, including:
- If the WIU is in Home or MTH Mode.
- The model of the TIU and if you're connecting via its USB or serial port.
- The type of the device hosting the DCS App and it's level of operating system
- How you're connecting the device and the WIU via WiFi.
- The software version of DCS in the TIU (it must be 6.1)
- The firmware level of the WIU (it must be 1.1).
