@Dave Hikel posted:MTH did discontinue the WIU, but not for lack of component availability.
So why did ATLAS just recent catalog the WIU as a for sale item?

@Dave Hikel posted:Super Mode is eliminated from the WTIU because it is no longer necessary. The purpose of Super Mode was directly linked to the use of the 900MHz radio. It was used to filter which commands were intended for which TIU's. Now that the WTIU uses 2.4GHz WiFi (or can be hard wired via ethernet cables) that filtering capability is built-in. Each WTIU will have a unique IP address, which allows for the same command filtering to be handled by the DCS app. This not only eliminates the need for Super Mode, but it also eliminates the limitation of DCS to only 250 switches and 250 accessories. Since the DCS app keeps track of WIU's and WTIU's by IP address, you can have more than 5 WIU/TIU combos or WTIU's, and each can have up to 5 AIU's.As I mentioned before, I think the OLD TIU with a WIU is currently the most desirable hardware package because it lets you use both the DCS remote (without tether) and the DCS app. However, I am very interested to get my hands on a WTIU when they come out. There have always been some weaknesses in the serial link between the TIU and WIU that make undetected command errors possible. When running from the app or DCS remote this generally isn't a big deal. If a command got corrupted and therefore ignored, you simply pressed the button on the app again. When running automated from a computer, these missed commands can be a big deal (not getting the speed 0 command to stop is a problem
). The WTIU gives MTH the opportunity to fix some of these 'under the hood" issues and make DCS better than it has ever been.
This makes sense as the APP will be networked with each WTIU or WIU/TIU combo. Super Mode on the remote broadcasted commands to each TIU whether they need it or not.
