Still promised you some comments on the configuration. In general, it is beneficial to keep the channel definition as short as possible. Each of the properties in the channel definition will be set, most often resulting in (serial) communication to the device, hence causing delays and potential for errors.
So, properties in the channel group that are the same in all configurations should be removed (for instance: “Blank on”, “Blanking” (although this seems on for one channel, is that on purpose?). Also, it is never a good idea to switch light sources by setting their state property directly. Rather, create a shutter associated with the device (using the Utilties adapter), and use only the Core-Shutter property in your configuration. You should also not need to add all the DAC voltages once you have a shutter device included, even when the DAC voltage is set to a constant, the actual voltage will be 0 as long as the shutter is closed. Such a configuration will result in significantly less chatter with the devices and better performance.
Of course, I may be missing something since I do not know anything about your microscope system, but most often these types of configurations result from a lack of understanding the (virtual) shutters available in MM and the advantages of using the auto-shutter concept. Clearly, we should do a better job at explaining, but I hope you can help!
