I have a problem with an MTH challenger that is perfectly described in this recent post. https://ogrforum.ogaugerr.com/...ps-responding-to-dcs
So it seems pretty clear that I need to update the unit’s chain file. However, from the instructions that I’ve read, a PC is needed near the TIU and a powered track to be able to perform the update. My problem is that my PC is 2 floors away, I don’t have a laptop and for most tasks, I use an IPad. So my question — is there any way to use the DCS WI-FI to perform the update? I’m afraid that I know the answer but I’m hoping there is some alternative.
