Hello Jeff — I am traveling so I can’t provide a “map” to the info, but look in ACP Help on how to control Readout Modes for “normal” operations. The ROModeInfo.txt configuration file contains instructions on which readout mode to use for plate solving (pointing updates) and for focusing, as well as “normal” images. You need to create this file. It might turn out that, after doing so, you can avoid the need for #readoutmode directives in your ACP Plans, if you always use the same mode for final images.
