Sorry you are having problems, especially as you are a long time H9 guy.
But, to help us help you, you should give a detailed description of your setup.
For example, you seem to be connecting to the H9 both by iPad and by Tech21. How is this ? At the same time, or different ?
What is the " small hot button" – please use the descriptions in the UM, or it is hard for us to understand you.
Have you re-initialized the H9 ? If not, please do.
Also, try different new cables.
Sorry if the above is obvious, but there are usually reasons why these things don't work.
