@Frank Mulligan posted:Well, it appears there are no physical connections on it. Except for power, completely wireless I presume? I may be mistaken, but I thought you could still use the handheld remote albeit tethered via a phone cord.@H1000 posted:Also curious, Did the WIU go through a redesign? Some vendors are posting pictures of it in a slightly new housing:
I think you (Frank) are mixing up WTIU and WIU.
The WTIU is a combined TIU that has a built in WIU, so it has all the track power and other connections plus a new antenna sticking out of the case.
Back to this topic, I do not think the WIU changed, I just think you are looking at the antenna end.
Per the WIU manual https://mthtrains.com/sites/de...ction/50as13515i.pdf
VS recent picture 
It is possible it changed slightly, but side by side all LEDs and function indicators are still in the same basic locations.
One note, the Logo and the WIU label is reversed compared to the earlier batches??
Again, there might be minor cosmetic differences in this batch, I have not ordered a new one to compare side by side.
