Return value Acknowledge ACK (06h) or Not Acknowledge NAK (15h) Operations with only one command, Video 1, Video2, Panel, and Camera Iris have to be combined somehow with the Common adjustment controls. Could be the single command values switch to the specific commands on those menus, then the common Up, Down etc controls act on them? If that's the case then the common control buttons will need to be duplicated on each tab for those controls, or perhaps a fixed section of the GUI with those buttons. Greying them out when the Normal, Mode, Language and all Camera operations *except* Iris are in use would be a good thing. The commands to be used with the Common adjustments, radio buttons? Commands with their own up/down, on/off etc should be normal buttons.
