Kevin,
3. I can see all 4 WIFI units, each one shows up as an independent SSID so eventually I want to be able to create a Super TIU, When is this software update going to be available? How many can you link? I need the maximum amount possible or at least the same number of TIU's. Is their a plan to accommodate the use of up to to 5, 7 or 10 WIFI units?
Super TIU is slated to be included the Pro version of the app, due out later this year.
4. Is their a plan to allow more than 5 TIU's to be put in to the super mode?
To the best of my knowledge, no there is not. However, you can try to add additional TIUs by "cheating", although this is not supported. For more information, refer to page 122-123 of The DCS Companion 3rd Edition.
This and a whole lot more is all in “The DCS Companion 3rd Edition", available for purchase from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book!
